jaw crusher working principle

jaw crusher working principle

A sectional view of the single-toggle type of jaw crusher is shown below.In one respect, the working principle and application of this machine are similar to all types of rock crushers, the movable jaw has its maximum movement at the top of the crushing chamber, and minimum movement at the discharge point. The motion is, however, a more complex one than the Dodge motion, being the resultant of the circular motion of the eccentric shaft at the top of the swing jaw. combined with the rocking action of the inclined toggle plate at the bottom of this jaw. The motion at the receiving opening is elliptical; at the discharge opening, it is a thin crescent, whose chord is inclined upwardly toward the stationary jaw. Thus, at all points in the crushing chamber, the motion has both, vertical and horizontal, components.

It will be noted that the motion is a rocking one. When the swing jaw is rising, it is opening, at the top, during the first half of the stroke, and closing during the second half, whereas the bottom of the jaw is closing during the entire up-stroke. A reversal of this motion occurs during the downstroke of the eccentric.

The horizontal component of motion (throw) at the discharge point of the single-toggle jaw crusher is greater than the throw of the Dodge crusher at that point; in fact, it is about three-fourths that of Blake machines of similar short-side receiving-opening dimensions. The combination of favorable crushing angle, and nonchoking jaw plates, used in this machine, promotes a much freer action through the choke zone than that in the Dodge crusher. Capacities compare very favorably with comparable sizes of the Blake machine with non-choking plates, and permissible discharge settings are finer. A table of ratings is given.

The single-toggle type jaw crusher has been developed extensively. Because of its simplicity, lightweight, moderate cost, and good capacity, it has found quite a wide field of application in portable crushing rigs. It also fits into the small, single-stage mining operation much better than the slower Dodge type. Some years since this type was developed with very wide openings for reduction crushing applications, but it was not able to seriously challenge the gyratory in this field, especially when the high-speed modern versions of the latter type were introduced.

Due to the pronounced vertical components of motion in the single-toggle machine, it is obvious that a wiping action takes place during the closing strokes; either, the swing jaw must slip on the material, or the material must slip along the stationary jaw. It is inevitable that such action should result in accelerated wear of the jaw plates; consequently, the single-toggle crusher is not an economical machine for reducing highly abrasive, or very hard, tough rock. Moreover, the large motion at the receiving opening greatly accentuates shocks incidental to handling the latter class of material, and the full impact of these shocks must be absorbed by the bearings in the top of the swing jaw.

The single-toggle machine, like the Dodge type, is capable of making a high ratio-of-reduction, a faculty which enables it to perform a single-stage reduction of hand-loaded, mine run ore to a suitable ball mill, or rod mill, feed.

Within the limits of its capacity, and size of receiving openings, it is admirably suited for such operations. Small gravel plant operations are also suited to this type of crusher, although it should not be used where the gravel deposit contains extremely hard boulders. The crusher is easy to adjust, and, in common with most machines of the jaw type, is a simple crusher to maintain.

As rock particles are compressed between the inclined faces of the mantle and concaves there is a tendency for them to slip upward. Slippage occurs in all crushers, even in ideal conditions. Only the particles weight and the friction between it and the crusher surfaces counteract this tendency. In particular, very hard rock tends to slip upward rather than break. Choke feeding this kind of material can overload the motor, leaving no option but to regulate the feed. Smaller particles, which weigh less, and harder particles, which are more resistant to breakage, will tend to slip more. Anything that reduces friction, such as spray water or feed moisture, will promote slippage.

Leading is a technique for measuring the gap between fixed and moveable jaws. The procedure is performed while the crusher is running empty. A lead plug is lowered on a lanyard to the choke point, then removed and measured to find out how much thickness remains after the crusher has compressed it. This measures the closed side setting. The open side setting is equal to this measurement plus the throw of the mantle. The minimum safe closed side setting depends on:

Blake (Double Toggle) Originally the standard jaw crusher used for primary and secondary crushing of hard, tough abrasive rocks. Also for sticky feeds. Relatively coarse slabby product, with minimum fines.

Overhead Pivot (Double Toggle) Similar applications to Blake. Overhead pivot; reduces rubbing on crusher faces, reduces choking, allows higher speeds and therefore higher capacities. Energy efficiency higher because jaw and charge not lifted during cycle.

Overhead Eccentric (Single Toggle) Originally restricted to sampler sizes by structural limitations. Now in the same size of Blake which it has tended to supersede, because overhead eccentric encourages feed and discharge, allowing higher speeds and capacity, but with higher wear and more attrition breakage and slightly lower energy efficiency. In addition as compared to an equivalent double toggle, they are cheaper and take up less floor space.

Since the jaw crusher was pioneered by Eli Whitney Blake in the 2nd quarter of the 1800s, many have twisted the Patent and come up with other types of jaw crushers in hopes of crushing rocks and stones more effectively. Those other types of jaw crusher inventors having given birth to 3 groups:

Heavy-duty crushing applications of hard-to-break, high Work Index rocks do prefer double-toggle jaw crushers as they are heavier in fabrication. A double-toggle jaw crusher outweighs the single-toggle by a factor of 2X and well as costs more in capital for the same duty. To perform its trade-off evaluation, the engineering and design firm will analyze technical factors such as:

1. Proper selection of the jaws. 2. Proper feed gradation. 3. Controlled feed rate. 4. Sufficient feeder capacity and width. 5. Adequate crusher discharge area. 6. Discharge conveyor sized to convey maximum crusher capacity.

Although the image below is of a single-toggle, it illustrates the shims used to make minor setting changes are made to the crusher by adding or removing them in the small space between the crushers mainframe and the rea toggle block.

The jaw crusher discharge opening is the distance from the valley between corrugations on one jaw to the top of the mating corrugation on the other jaw. The crusher discharge opening governs the size of finished material produced by the crusher.

Crusher must be adjusted when empty and stopped. Never close crusher discharge opening to less than minimum opening. Closing crusher opening to less than recommended will reduce the capacity of crusher and cause premature failure of shaft and bearing assembly.

To compensate for wear on toggle plate, toggle seat, pitman toggle seat, and jaws additional shims must be inserted to maintain the same crusher opening. The setting adjustment system is designed to compensate for jaw plate wear and to change the CSS (closed side setting) of the jaw crusher. The setting adjustment system is built into the back frame end.

Here also the toggle is kept in place by a compression spring. Large CSS adjustments are made to the jaw crusher by modifying the length of the toggle. Again, shims allow for minor gap adjustments as they are inserted between the mainframe and the toggle block.

is done considering the maximum rock-lump or large stone expected to be crushed and also includes the TPH tonnage rate needing to be crushed. In sizing, we not that jaw crushers will only have around 75% availability and extra sizing should permit this downtime.

As a rule, the maximum stone-lump dimension need not exceed 80% of the jaw crushers gape. For intense, a 59 x 79 machine should not see rocks larger than 80 x 59/100 = 47 or 1.2 meters across. Miners being miners, it is a certainty during day-to-day operation, the crusher will see oversized ore but is should be fine and pass-thru if no bridging takes place.

It will be seen that the pitman (226) is suspended from an eccentric on the flywheel shaft and consequently moves up and down as the latter revolves, forcing the toggle plates outwards at each revolution. The seating (234) of the rear toggle plate (239) is fixed to the crusher frame; the bottom of the swing jaw (214) is therefore pushed forward each time the pitman rises, a tension rod (245) fitted with a spring (247) being used to bring it back as the pitman falls. Thus at each revolution of the flywheel the movable jaw crushes any lump of ore once against the stationary jaw (212) allowing it to fall as it swings back on the return half-stroke until eventually the pieces have been broken small enough to drop out. It follows that the size to which the ore is crushed.

The jaw crusher is not so efficient a machine as the gyratory crusher described in the next paragraph, the chief reason for this being that its crushing action is confined to the forward stroke of the jaw only, whereas the gyratory crusher does useful work during the whole of its revolution. In addition, the jaw crusher cannot be choke-fed, as can the other machine, with the result that it is difficult to keep it working at its full capacity that is, at maximum efficiency.

Tables 5 and 6 give particulars of different sizes of jaw crushers. The capacity figures are based on ore weighing 100 lb. per cubic foot; for a heavier ore, the figures should be increased in direct proportion to its weight in pounds per cubic foot.

The JAW crusher and the GYRATORY crusher have similarities that put them into the same class of crusher. They both have the same crushing speed, 100 to 200 R.P.M. They both break the ore by compression force. And lastly, they both are able to crush the same size of ore.

In spite of their similarities, each crusher design has its own limitations and advantages that differ from the other one. A Gyratory crusher can be fed from two sides and is able to handle ore that tends to slab. Its design allows a higher-speed motor with a higher reduction ratio between the motor and the crushing surface. This means a dollar saving in energy costs.

A Jaw crusher on the other hand requires an Ely wheel to store energy. The box frame construction of this type of crusher also allows it to handle tougher ore. This design restricts the feeding of the crusher to one side only.

The ore enters from the top and the swing jaw squeezes it against the stationary jaw until it breaks. The broken ore then falls through the crusher to be taken away by a conveyor that is under the crusher.Although the jaws do the work, the real heart of this crusher is the TOGGLE PLATES, the PITMAN, and the PLY WHEEL.

These jaw crushers are ideal forsmall properties and they are of the high capacity forced feed design.On this first Forced Feed Jaw Crusher, the mainframe and bumper are cast of special alloy iron and the initial cost is low. The frame is ribbed both vertically and horizontally to give maximum strength with minimum weight. The bumper is ruggedly constructed to withstand tremendous shock loads. Steel bumper can be furnished if desired. The side bearings are bronze; the bumper bearings are of the antifriction type.

This bearing arrangement adds both strength and ease of movement. The jaw plates and cheek plates are reversible and are of the best-grade manganese steel. The jaw opening is controlled by the position of an adjustable wedge block. The crusher is usually driven by a V-to-V belt drive, but it can be arranged for either V-to-flat or fiat belt drive. The 8x10 size utilizes a split frame and maybe packed for muleback transportation. Cast steel frames can be furnished to obtain maximum durability.

This second type of forced feed rock crusher is similar in design to the Type H listed above except for having a frame and bumper made of cast steel. This steel construction makes the unit lighter per unit of size and adds considerable strength. The bearings are all of the special design; they are bronze and will stand continuous service without any danger of failure. The jaw and cheek plates are manganese steel; and are completely reversible, thus adding to their wearing life. The jaw opening is controlled by the position of an adjustable wedge block. The crushers are usually driven by V-to-V but can be arranged for V-to-flat and belt drive. The 5x6 size and the 8x10 size can be made with sectionalized frame for muleback transportation. This crusher is ideal for strenuous conditions. Consider a multi jaw crusher.

Some jaw crushers are on-floor, some aboveground, and others underground. This in many countries, and crushing many kinds of ore. The Traylor Bulldog Jaw crusher has enjoyed world wide esteem as a hard-working, profit-producing, full-proof, and trouble-free breaker since the day of its introduction, nearly twenty years ago.

what is a jaw crusher | advantages, types, parts and specifications | quarrying & aggregates

The series of jaw crushers produced by Rayco are widely used in mining and aggregate crushing industries. They are specially developed for crushing the hardest ores and rocks, and are mainly used as primary crushers.

When working, the motor drives the belt and pulley to move the movable jaw up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, thereby pushing the movable jaw plate closer to the fixed jaw plate, and the material passes through the two jaws. The squeezing and rolling between the plates realize multiple crushing.

When the movable jaw descends, the angle between the toggle plate and the movable jaw becomes smaller. The movable jaw plate leaves the fixed jaw plate under the action of the pull rod and the spring, and the crushed material passes through the discharge port in the lower jaw cavity freely under the action of gravity Unload.

When crushing high hardness and strong corrosive materials, C6X can accomplish the task very well. Its equipment structure, manufacturing technology and material selection determine the high strength of its body. Not only can it be used for coarse crushing of the hardest rocks and ore, but also can be continuously produced in the most demanding production environment on the ground and underground to ensure the maximum production efficiency of customers.

jaw plates: how to choose the right one for different types of jaw crushers | fote machinery

The jaw plate is an important part in the jaw crusher equipment, and its service life directly affects the whole jaw crusher equipment. Therefore, you must consider the hardness and toughness of the jaw plate when you want to choose a correct one.

The wear of jaw plate depends on the types of your material and other variables such as material sizes. Too many fines enter the jaw crusher cavity will accelerate the wear speed of jaw plates because the fines fills the valleys which is necessary for the crusher to crush efficiently.

Generally, a jaw crusher finishes the crushing process by squeezing the material between stationary and moving jaw plates. The peaks and valleys of the jaw plates are offset from one another and use the mechanical advantage of leverage to break the rock.

Without this, the crusher has to rely on energy and friction to crush the rock. The compaction will also impose increased loads on the jaw crusher plates as much as five times the normal crushing force.

If the feeding material is over-sized, it also seriously affects the service life. In most applications, the reduction ratio of a jaw crusher is 6 to 1. Exceeding the reduction ratio will generate the crushing forces that break the crushers design limits and affect your overall production and machine performance.

That the jaw plate is severely worn can lead to uneven particle size and low efficiency, which indicates that you have to replace the jaw plates. If you want to choose a correct one, you should consider their different materials according to the purpose and real situation.

High manganese steel contains a relatively high carbon content which plays an important role in wear resistance. In general, the hardness increases with the growth of carbon content. Under non-strong impact conditions, increasing the carbon content is beneficial to improve the wear resistance of steel. And this is why high manganese steel has good deformation hardening ability.

Medium manganese steel has strong hardening ability and stable performance, which creates the function of self-protection when the law plates are subjected to impact and wear. The medium manganese steel jaw plate has achieved good results in the actual production process, and improves service life by 20% compared with that of the high manganese steel jaw plate.

Medium-carbon-low-alloy cast steel is a widely used wear-resistant material at present. Mainly because of its high hardness and suitable toughness, it can resist fatigue spalling caused by repeated extrusion of materials, and shows good wear resistance.

It can also be adjusted by composition and heat treatment to make the hardness and toughness be changed within a large range. That shows high flexibility strong adaption to the requirements of different working conditions.

The hardness of the material-The hardness of the material is also an important factor in choosing the jaw plate. The material hardness determines the toughness and strength requirements of the corresponding jaw plate.

For large jaw crushers, the crushed material is huge-block, which forces the jaw plate to accept strong impact and wear. For that situation, the high manganese steel can give full play to the advantages of good toughness and hardness.

Note: If the flare angle between the moving and fixed jaw plates is too large, it is easy to cause the sliding of the abrasive, deformation and insufficient hardening of the high manganese steel. So sometimes you should adjust the appropriate flare angle during use.

If you need to deal with materials with high hardness such as granite, quartz stone, concrete, etc., the medium manganese steel is the most suitable because of its strong hardening ability. Besides, it has a self-protection mechanism when crushing high hardness materials, which can greatly reduce the wear rate.

Medium and small sized jaw crushers usually bear a low impact load, so under such conditions, medium-carbon-low-alloy steel materials are more suitable. Not only can the disadvantages of high manganese steel difficult to reach the application hardness be avoid, but it also bring good technical and economic benefits.

Processing Materials: pebble, calcite, granite, quartz, concrete, dolomite, bluestone, limestone, iron ore, coal gangue, construction waste, ferrosilicon, basalt, sandstone, rocks, ore, glass, cement clinker and some metals.

While the working principle of cone crusher is laminated crushing. The rolling wall continuously moves toward the broken wall, and the material between the two is squeezed to be pulverized.

Here is the working principle of impact crusher. The toothed counter-back plate rebounds and falls freely after the material reaches the top of the vortex breaking chamber and then hits and crushes constantly with subsequently upward impacting materials.

Jaw crusher processes the hardest and medium-hard stones as the first crusher, and impact crusher and cone crusher can both act as secondary crushing devices, but the hardness of the two broken materials is not the same.

Cone crusher mainly crushes some harder materials, such as granite, basalt, river pebbles and so on, while impact crusher is used to crush the materials that are not so hard, such as limestone, limerock, etc. These materials above can be crushed firstly by jaw crusher.

The discharge size of jaw crusher is widely adjusted from 10-400mm, which is coarser than that of the second-stage crusher. But the discharge sizes of the secondary crushers are not the same. Generally, the discharge granularity of cone crusher is finer than that of impact crusher.

In the actual production, jaw crusher can be used wisely in mining, construction, building materials, etc. But cone crusher is more often used in ore processing and impact crusher in construction and building material processing.

The jaw crusher is a kind of early crushing device. With simple and firm structure, reliable operation, easy maintenance and service and relatively low costs in production and construction, jaw crusher is still widely used in coarse, medium and fine crushing for various ores and rocks with compressive strengths ranging from 147 to 245 MPa in metallurgy, chemistry, building materials, electricity, transportation and other industries.

The working principle is: the motor drives the belt and the pulley, and the mobile jaw is moved up and down through the eccentric shaft. The angle between toggle plate and mobile jaw increases when mobile jaw moves up, thereby the mobile jaw is closer to the fixed jaw, at the same time the materials are crushed or chopped to achieve the purpose of crushing;

the angle between toggle plate and mobile jaw decreases when mobile jaw moves down, the mobile jaw is separated from the fixed jaw under the action of the pull rod and the spring, meanwhile the crushed materials are discharged from the lower mouth of the crushing chamber.

The inertia required to crush the materials is provided by the flywheel, and the eccentric shaft generates eccentric motion which results in the gap getting closed. With the continuous rotation of motor, the mobile jaw works periodically to crush and discharge materials and finally achieve mass production.

Jaw crusher is a kind of heavy-duty machine and therefore require the solid construction. The external frame is usually made of cast iron or steel. The jaws are usually made of cast steel fitted with replaceable gaskets which are made of manganese steel or Ni-hard (Ni-Cr alloy cast iron). Jaw crushers are usually constructed in sections so that they can be transported easily when they are brought underground for operation.

In the mining and construction crushing industries, the jaw crusher at the front end of the production line, and its performance directly affects the quality and operation of the whole production line.

HXJQ Corporation has brought new breakthroughs in the production and upgrading of mines and gravel production lines and produced a series of jaw crushers in high quality and high standards with its over 40 years experiences and cases in crushing industry according to the market demand.
