Jaw stone crusher is heavy duty machines and hence need to be robustly constructed. The movable jaw and static jaw are made up of the crushing chamber. It stimulates the movement of the two jaws of the Animal and completes working. Widely used in mining smelting, building materials, roads, railways, water conservancy, and chemical industries in a variety of ore and large pieces of material crushing. The classification of Jaw crusher: single toggle jaw crusher, double toggle jaw crusher, hydraulic jaw crusher, impact jaw rock crusher, mobile jaw stonecrusher, etc. Which jaw crusher better single toggle or double toggle.

The movable jaw is suspended from the mandrel and swings from side to side. When the eccentric axis rotates, the connecting rod moves up and down. And drives the two thrust plates to move back and forth as well. Thus pushing the jaw to move left and right to move back and forth, realizing crushing and discharging.

This kind of crusher adopts a crank two-bar linkage mechanism. Although the moving jaw is subjected to a great crushing reaction. Its eccentric shaft and connecting rod are subjected to a little force. So it is often made into large and medium-sized machines for crushing hard materials in the industry. In addition, when the crushers work, the movement track of each point on the moving jaw is a circular arc with the center of the center axis.

The radius of the circular arc is equal to the distance from the point to the axis. The upper arc is small, the lower arc is large, and the crushing efficiency is low. The fragmentation ratio is generally 3-6. Because the movement track is simply so-called a single toggle jaw crusher. The structure of the single toggle jaw crusher is compact and simple, and the force of transmission parts such as eccentric shaft is small. The vertical displacement of the movable jaw is small, the material is less excessively broken and the wear of movable jaw plate is small.

The upper end of the movable jaw is directly suspended on the eccentric shaft. As the connecting rod of the crank connecting Rod mechanism, the lower end of the movable jaw is supported on the back wall of the frame by the thrust plate. When the eccentric axis rotates, the track of each point on the movable jaw is from the circumference line of the suspension point (the radius is equal to the eccentric distance), and gradually becomes an ellipse. The movement track of each point on moving jaw is more complex in this kind of machine, so it is called a double toggle jaw crusher.

Compared with the single toggle jaw stone crusher, the double-toggle jaw crusher has the following advantages: less weight, fewer components, more compact structure, a better filling degree in the crushing chamber, even crushing of the loaded material block, and forced unloading of the finished product by moving the lower jaw. Therefore, productivity is higher, 20-30% higher than that of the single-toggle of the same specification. And the material block has a bigger up-down rolling motion in the lower part of the moving jaw, so it is easy to be discharged in the shape of a cube.

First of all, the choice of the crusher machine is determined by the size of feeding and discharging. The feeding degree, product size is coarse, choose the big jaw crusher or more coarse, otherwise use medium and fine. In the calculation of feed size, the maximum open-side feed size is multiplied by 0.85. And the average size of the product is calculated by dividing the maximum feed size by the crushing ratio. In general, the feed size distribution of jaw crushers cannot exceed 10 %. If more than 10 %, the power consumption will increase and the product size will become flaky.

Secondly, when choosing the liner of jaw stone crushers equipment, the user must consider three factors: output, power consumption and wear resistance of liner. In general, the following principles should be followed: maximum feeding size, size change, the size distribution of feeding, the hardness of a material, Abrasion Resistance of materials. The longer the jaw crusher liner, the higher the power consumption, hard materials choose short liner, soft materials choose longliner. In the distribution of materials, thin materials choose short liner, coarse materials choose longliners.

Finally, the crusher in the work, feeding to uniform, can not segregation. If the uneven feeding will occur production capacity reduction, product size is too large, frequent spring action, bowl-shaped bearing pressure, power consumption rise. And it must have iron remover to prevent crushing chamber over iron. If frequent over iron, it may cause shaft broken accident. The moisture content of viscous materials can affect the amount of material through. In terms of moisture content of materials, generally not more than 5 %. In the use of power: Standard stone crusher should reach 75% ~ 80 %, short head crusher should reach 80% ~ 85 %.

difference between single & double toggle jaw crusher

difference between single & double toggle jaw crusher

A double toggle jaw crusher is much larger, heavier, more moving parts and lower throughput than modern single toggle jaw crushers. The lower throughput statement is a bit misleading because its partially attributed to the type of bearings they have versus modern crushers, so if one was to upgrade the bearings, throughput could be closer to that of a modern jaw.

Anyway, double toggle jaw crushes are really more about where the eccentric is located than anything. In a double toggle jaw crusher, the eccentric is located behind the swinging jaw. This has two main effects, it keeps the eccentric out of harms way because there is no shock loading from the rock being crushed being transferred to the eccentric shaft and bearings. The other effect is a limited plane of motion for the swinging jaw which contributes to its lack of productivity. The jaw moves like a swinging door that is hinged at the top and is being pushed open and pulled closed at the bottom. One toggle plate goes from the bottom of the eccentric arm to the bottom of the swinging jaw, the other toggle plate goes from the opposite side of the bottom of the eccentric arm to a fixed point at the very back of the jaw crusher frame.

In contrast, the single toggle jaw crusher has fewer shafts and bearings and only one toggle which goes from the bottom of the swinging jaw to a fixed point at the back of the jaw crusher. The eccentric is located at the top of the swinging jaw and is part of the shaft. The advantage of this is that the jaw has two motions that are happening at the same time. It has the same swinging door motion that the double toggle has, but also has the up and down motion from the eccentric.

The advent of curved jaw crusher wearing plates made an approach other than segmental layout analysis desirable for prediction of capacities. For some time it had been known that the drawing board capacities of crushers using these plates had to be considerably modified by complicated experience factors to achieve agreement with results. Because these apparent capacities could be readily increased severalfold by minor crushing chamber shape changes, it was necessary that the utmost precaution be taken in predicting capacities of jaw plates modified for nonchoking, special wear characteristics, or any other reason.

While this paper is concerned principally with standard type single-toggle crusher capacities, the evaluation of data obtained with these machines is simplified by comparative reduction to the 10 x 7 in. Blake-type equivalents upon which the summary of the preceding paper was made. Convertibility of data from one type of crusher to the other also tends towards confirmation of both. The agreement of these data is sufficient to be considered complimentary. Consequently the feed factors, f, previously reported for Blake crushers are slightly adjusted to an average with the single-toggle crusher results.

d is the apparent density of the broken product in pounds per cubic foot. (If the true specific gravity of the feed is known, 40 pct voids may be assumed and d becomes 37.4 times sp gr). w is the width of crushing chamber in inches. y is the open side setting of the crusher, in inches. In the case of corrugated jaw plates it is measured from the tip of one corrugation to the bottom of the valley opposite. t is the length of jaw stroke in inches at the bottom of the crushing chamber. It is the difference between open and close-side settings. n is rpm, or crushing cycles per minute. a is the nip-angle factor.

To bring the Blake and single-toggle type crusher capacity test results to common terms for evaluation, all data are converted to terms of 10 x 7 in. Blake-type performance at conditions of 100 lb per cu ft, 10 in. chamber width, 250 rpm, 0.65 in. stroke, 3-in. open-side setting, and 18 nip-angle. (The nip-angle of the 107 in. Blake is 18 at 3-in. setting.) The single-toggle crusher performances are also divided by the eccentric throw to bring this effect to unity.

In the Blake-type crusher tests, no capacity variation was noted for materials of different crushabilities, even though a wide range of materials was tested. These feeds had impact strengths ranging from 2.8 to 31 ft lb per in. of thickness as measured by the Bond method, (potash, coke, soft hematite, limestones, traprock, taconites.)

Greater differences in crushability-capacity effect than those just discussed for single-toggle type crushers have been reported by investigators working with small Dodge-type crushers. However, these crushers have rubbing motion between the jaws at the discharge, and in addition have very little jaw stroke at the discharge.

Double Toggle Jaw Crushers are preferred for crushing ususually hard, abrasive rocks and other materials like ferroalloys and glass. They differ substantially from other types of crushers. There is no rotary motion in the crushing cycle and all crushing is done by compression of the feed material between two massive jaws plates. The moving jaw compresses the material against the stationary jaw. Jaw plates can be either smooth or corrugated.

Double Toggle Jaw Crushers have one jaw fixed, while the other pivots about a top hinge. This moving jaw is shaped to move firmly and squarely against the material. There is no rubbing or grinding. Only compression, which produces a generally cubical product with minimum fines. The moving jaw is very well balanced, so 95% of the drive motor power is ued for crushing. While only 5% of the power is needed to move the jaw itself. As a result of this high mechanical efficiency, double Toggle Jaw Crushers require smaller size motors, keeping power costs down. Behind the stationary jaw are shims, used to adjust the distance between the lower ends of the jaws (closed side setting). The setting determines the output product size. There is also an arrangement of safety arm for protection from us-crushables accidental overloads.
