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 8211 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.

Working principle advantages of double toggle jaw crusher 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.
Single vs double toggle jaw crusher single versus double toggle jaw crusher jun 20 2019 single toggle jaw crusher vs double toggle jaw crusher jaw crusher is the most monly crusher used for primary crushing it has two types single toggle and double toggle in the double toggle crusher the rotation of an eccentric shaft causes a vertical reciproing motion of a ponent called a pitman that is.
Salient feature of single toggle jaw crusher the features of single toggle jaw crusher are same as double toggle jaw crusher but the difference in single toggle is crushing and stroking is done by pitman only.
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.
What are the advantages of a single toggle blake jaw crusher quora single versus double toggle jaw crusher a double toggle jaw crusher is much larger heavier more moving parts and lower throughput than modern single.
