working principle of stone crusher

Hammer crusher works on the principle that basically depends on the usage of installed chassis and high-speed kinetic hammer. The spindle of the stone crusher is composed of a hammer shelf, a hammerhead that is hanging on the shelf, and a sieve equipped on the lower half of the machine. Spindle, disk (shelf), and hammer, pin form a rotating body called rotor. The motor drives the rotor rotating at high speed in the crushing cavity, and the materials from the upper mouth feed into the machine, thus totally crushed by the high velocity of the hammer blow after impacting, shearing and grinding. A sieve is set below the rotor, particle bigger than the mesh size is kept staying on the surface be crushed the grained again. Once the size is small enough to across the sieves meshes, the granules can be expelled. The type of stone crusher can be divided in many ways as follows:

The working principle of a stone crusher has a lot to do with its structure and characteristics. Stone crushers construction specifications include casing, rotor, sieve, the feed board, back plate, gear and other parts. We now briefly illustrate some of these parts.

1.The casing part consists of the feed port blocking plate, lower box, upper box and side walls. Each part is connected by bolts, all laced with manganese steel casing wall linings, under cabinet, side walls and the rear cover with a welded steel plate on both sides of the bearing to support the rotor in order to place a steel plate welded into bearing support. For the facilitate maintenance, adjustment and replacement purpose, the front and rear sides of the lower housing have opened manholes.

3.Sieve and other parts are consists of hammerhead screw connected to the box with high manganese steel liner. The back plate can be replaced after worn out, which makes the maintaining process more convenient.

4.Safety devices are designed in order to prevent metal objects from the crushing accidents. Rock crusher generally has safety devices. The spindle is equipped with safety copper sleeve, which is connected with a safety pin.

jaw crusher working principle

jaw crusher working principle

Jaw crusher is widely used in industrial and mining enterprises , this is because the aircraft structure is relatively simple , and has a large range of models . Jaw crusher is mainly used as the primary crusher. It can be used with mineral processing equipment, gravel ancillary equipment, it also can be used alone.

Structure of jaw crusher mainly include frame, eccentric shaft, big pulley, flywheel, moving jaw, side guard plate, toggle plate, toggle plate back seat, adjusting screw gap, the reset spring, fixed jaw plate and movable jaw etc. , the toggle plate also play a role as insurance bracket . Working part of jaw crusher is two pieces of jaw plate, one is fixed jaw plate (fixed jaw), vertical (or slightly upper camber) fixed in the front wall of the body, and the other is movable jaw plate (moving jaw), location inclined to form the next big small crushing chamber (working chamber) and the fixed jaw.

Jaw crusher for crushing materials work, is the material between the two pieces of jaw plate crushing. Motor drive transmission mechanism driven jaw plate hanging around the shaft relative to the fixed jaw do periodic reciprocating motion, sometimes close, sometimes leaving in the process of moving jaw plate close to the fixed jaw plate, is the material between the two jaw plates pressed on the subject broken, bent and broken fracturing, the process was moving away from the fixed jaw plate, the material has been crushed under the action of gravity, through the discharge port of discharge.

Stone crusher machine divides into a mining crusher and a medical crusher. The mining crusher equipment divides into jaw crusher, gyratory crusher, impact crusher, cone crusher, hammer crushers, roller crushing, mobile crusher, etc. according to the principle of crushing. Jaw crusher for sale

Gyratory crusher is a new type of crusher which can replace fine jaw crusher or cone crusher. The gyratory crushing equipment has a bright future in the mineral processing market. Its working part is a high-speed rotary crushing roller, which is coupled with a pair of curved crushing plates arranged symmetrically on the left and the right to form two optimal crushing cavities for the pliers. Under the action of the eccentricity of the main shaft, the crushing roller makes a transverse rotary motion. And make it produce strong cyclic extrusion pressure, continuous progressive on the two crushing cavities of the material alternately broken. Then the product from the two discharge mouth constantly discharge.

The primary gyratory crusher breaks the material by feeding mouth into the two rollers between the extrusion crushing, finished materials naturally fall. In case of too hard or can not be broken, the roller crusher by hydraulic cylinder or the role of the spring can automatically retreat. So that the gap between the rollers increase, too hard or can not break down, so as to protect the machine from damage. The opposite two rollers have a certain gap, change the gap, you can control the product maximum discharge granularity. Rotary crusher is the use of a pair of opposite rotation of the round roll. Four-roll crusher is the use of two pairs of opposite rotation of the round roll crushing operations.

JXSC tooth roller crusher mainly uses the special wear-resistant tooth roller high speed rotation to crack the material (the traditional tooth roller crusher uses the low speed extrusion crushing) , has formed the high productivity mechanism. The roller crusher with saw teeth on the surface of both rollers mainly plays the role of cracking and tearing, and also has the role of crushing, grinding and crushing. The broken teeth arranges in a spiral shape. The small particles in the feed are easily discharged through the gap between the broken rollers. The big pieces are broken by the shearing and tensile force of the teeth. The situation that the material is broken without control in the traditional crusher is improved.

The good effect of fine crushing 1. There are cracks and other weak spots or defects in almost any particle. The double-cavity gyratory crushing, because of the multi-directional pressure on the material, under the interaction of multi-layer material, makes the material easier to be broken from the defect. Then it can obtain high crushing rate and produce more fine-grained products. 2. Due to Lamination crushing, even with a larger outlet, a finer product and a finer product size distribution can be obtained. 3. The high-frequency swing crushing roller can break the material more times than the traditional crusher in the crushing chamber, so the size of the discharging material is a greatly reduce. The production practice shows that when the size of the feed is 80 mm, the content of 12 mm can reach 80 %, and the content of 6 mm can reach 50%.

1. Double-chamber gyratory crusher is a crusher machine that continues working with a double-chamber. The crusher equipment changes the discontinuous working mode of single chamber of jaw crusher. 2. The characterize is that producing more fine products under the condition of larger discharge port. Under the premise of ensuring fine products, the larger discharge port can obviously have more processing capacity.

Small work vibration Gyratory crusher has no supporting structure of the elbow plate. The crushing roller works in a balanced rotary state. So the vibration is small and the noise is low. It can work smoothly on the steel frame without foundation.

1. When double cavity rotary crusher machine crushing materials, the roller swing movement. The crushing force mainly occurs near the eccentric position of the crushing roller, forming high power density crushing. Then forming the crushing process with the circular movement of the eccentric position of the crushing roller. Because the crushing force concentrates on a small amount of material in a section of the crushing chamber, the crushing force uses in the operation is smaller and the energy utilization rate is high. Therefore, it has obvious energy-saving effect. 2. The crushing machine continuous working, which can make full use of the output energy of the driving motor. And it can make use of the strong kinetic energy of debris splashing produced in the process of rock crushing to carry out the re-crushing of the adjacent rocks. Repurposing the secondary energy. 3. As fully utilize the energy, the production practice has proved that the electricity consumption per ton of ore processing is generally 0.5 degrees.

1. The double chamber rotary crusher works smoothly on the steel frame without foundation. Then civil construction is easier and installation is more convenient. 2. The crusher machine parts are all used expansion sleeve connection. So it is very convenient to disassemble and assemble, repeated disassembly will not affect the assembly accuracy of the machine. 3. Easy adjustment of discharge opening and simple structure. 4. Only use grease lubrication, management, and maintenance of convenient, low cost.

1. The two cone shapes of the gyratory crusher are steeply inclined. The movable cone is upright, and the fixed cone is an inverted truncated cone which in order to increase the need for feeding ore. Nevertheless, cone crusher has two cone shapes, which are gently inclined, vertical frustum cone. There is a certain length of parallel ore crushing area (parallel belt) between the two cones which in order to control the requirement of mineral product granularity. Because of the medium and fine crusher, and coarse crusher different. It is to crush product quality and production capacity as the primary consideration.

4. The gyratory stone crusher changes the size of the ore discharge port is using to adjust the rise or fall of movable cone. Cone crushers adjust the height of the fixed cone to realize theadjust of the width of the ore discharge mouth.

One of the most commonly used crushing machine is the jaw crusher. It is a heavy-duty machine that is generally used for crushing different kinds of raw materials into smaller pieces. The jaw crushers can be seen in the mining and disposal industry where large rocks need to be crushed into smaller pieces for further use.

The working principle of the jaw crushers is very simple. Powered by a diesel or gas motor, the jaw crusher brakes materials in a crushing chamber. The materials are pushed inside the chamber from the top opening and when crushed they are released through the bottom opening. The crushing power of the jaw crushers depends on the size of the chamber. The bigger the chamber, the more powerful the jaw crusher. The crushing process can be basically explained as a process where the materials are sandwiched between two jaw plates. The movable jaw plates squeeze and crush the materials into several small pieces.

There are two main types of jaw crushers: double toggle and overhead eccentric jaw crusher. The only difference between these two crushers is the location of the pivot joint. In the overhead eccentric jaw crushers, the pivot joint is located at the bottom of the chamber, while at the double toggle crushers, the pivot joint is on the top. The double toggle jaw crushers are more preferred, simply because these crushers are described as fuel-efficient and easy to operate machines.

The jaw crushers can be used for crushing all kinds of hard materials quickly and efficiently. Powerful and highly efficient, the jaw crushers are essential pieces of equipment in the construction and mining industry. They can be used in combination with other crushing machines for more efficient performance. In most cases, the jaw crushers are used as primary crushing machines in projects where high quality materials are not needed.

the models and parameters of cone crusher | hxjq

Processing Materials: river pebbles, granite, marble, limestone, fluorite ore, gold ore, barite, calcite, dolomite, bluestone, glass, basalt, iron ore, etc.

The cone crusher is a kind of stone crusher machine applied for metallurgy, building, road construction, chemical engineering, etc. It is suitable for medium and fine crushing with the features of high crushing ratio, high efficiency, low energy consumption and uniform particle size.

There are different models in HXJQ divided by different crushing principles and different particle sizes: single cylinder hydraulic cone crusher, multi-cylinder hydraulic cone crusher, hydraulic cone crusher, Symons cone crusher (compound cone crusher), and spring cone crusher. At present, the most advanced one is the single cylinder hydraulic cone crusher, and the most popular one is the Symons cone crusher.

The structure of single-cylinder hydraulic cone crusher is simple. Its characteristics are the steep cone, high swing frequency, and small eccentric distance. The unique design structure of bottom single cylinder can complete the three functions which can adjust the discharge opening directly, prevent ferric materials, and clear chambers.

The Symons cone crusher has the hydraulic chamber-cleaning system which can reduce its downtime. This machine adopts the lubrication grease system which avoids the defects of water-supplying and discharging block as well as mixing the water and oil easily. The spring insurance system is an overload protection device, which can make the foreign matter and iron ore go through the crushing chamber without damage.

When the single-cylinder hydraulic cone crusher is working, the motor drives the small gear of the crusher, the pinion drives the large gear, and the large gear assembly drives the eccentric sleeve assembly and the spindle assembly, which are centered on the theoretical vertical line, and rotate in the copper bushing.

The spindle assembly in the eccentric copper sleeve with the center line of the spindle can realize the rotating material being crushed by the swinging inner cone, and the crushed material is discharged from the discharge port.

When the compound cone crusher is working, the motor drives the eccentric sleeve to rotate by the V-belt, transmission shaft and bevel gears. The moving cone rotates under the action of the eccentric sleeve. The material is continuously crushed and impacted in the crushing chamber, then the needed size of the material after crushing will falls under the gravity and be discharged from the bottom. Symons cone crusher controls the particle size of material according to reducing the size of the discharge opening, so it is not suitable for ultra-fine sand or sand making.

The technology of single-cylinder hydraulic cone crusher is more advanced and higher efficient to operate. Under the condition of the constant crushing chamber, the maximum feeding size and productivity can keep constant, it has higher output, longer liner life, and lower operating costs. Its mainframe weight is 5700 to 36,300 kg, the weight of Symons cone crusher is 9980 to 43,270 kg, and its volume and weight are smaller than Symons cone crusher. Therefore, it is more convenient and quick to install and transport, as well as lift and change parts.

Jaw crusher, cone crusher and impact crusher are the mainstream crushers used in mining industries. Jaw crusher and cone crusher are the classical laminated crushers, and also the most popular crushers, while impact crusher adopts impact crushing principle. In general, jaw crusher is used as the primary crusher, and cone crusher and impact crusher as the secondary. And they always combine with each other in the whole crushing line during the crushing process.

Jaw crusher and cone crusher adopt the laminating crushing principle, known as extrusion crushing principle. Although the crushing actuators are different, the nature of crushing does not make much difference.

During the crushing process, the cone crusher adopts the extrusion between the mortar wall and the crushing wall, and the jaw crusher adopts the extrusion between the mobile jaw and the fixed jaw.

Impact crusher adopts the impact crushing principle, and materials are impacted and crushed between hammer and impact plate. Due to the frequent impact, the wearing parts are easy to damage, so impact crusher has a high requirement on the wear-resistance materials.

The jaw crusher, cone crusher and impact crusher are widely used in a variety of materials, but they have different applicability. The jaw crusher can almost meet the requirements of all materials.

Cone crusher also has the wide applications, ans it can crush high-hardness materials in high efficiency. However, impact crusher is generally used for crushing soft materials such as limestone because its crushing principle and wear-resistant parts, and impact has a good performance in shaping.

When choosing crusher machines, a comparison should be conducted according to different situations. Generally, jaw crusher is used for primary crushing, and for second crushing or fine crushing, a large ore-dressing plant always chooses the cone crusher, and a medium or small plant chooses the impact crusher.

Generally, jaw crusher is suitable for all kinds of crushing lines, and it is relatively cheaper than cone crusher because of the large market. Though impact crusher has a cheap price, it has several wear-resistant parts such as hammer and impact plate, which should be replaced after several times uses, so impact crusher has a high using cost.

Although cone crusher is relatively expensive, the wear-resistant parts have long service life to avoid the worries of changing parts frequently. Therefore, cone crusher has higher performance-price ratio than impact crusher in the long run.

HXJQ as a professional cone crusher manufacturer has produced crushers for more than 40 years, and we have the crushers with the lowest cone crusher prices and highest quality. If you have any problems in the selection of equipment, please timely consult HXJQ, there are experts who will guide for you in the whole process and choose the most suitable, cheapest, and best-performance equipment for you.
