Industrial Rock Crushers employ two planer crushing surfaces set at a small angle to each other and convergent downward. One plane is fixed and the other is pivoted either top or bottom allowing a reciprocating motion when pushed by a pitman-toggle arrangement activated by an eccentric drive. The 3 common variations of the jaw crusher drive system are describe here.
The purpose of this article is to obtain a comprehensive mathematical description of the kinematics of a double-toggle jaw crusher. The driving mechanism of the crusher is modeled as a planar six bar linkage. Two closed position vector loops that characterize the configuration of the mechanism are used to derive expressions for the angular position, velocity and acceleration of the moveable jaw.
Many types of crushers use rotating hammers and other crushing elements to reduce materials by impact, shear or attrition. Jaw Crushers, however, crush by compression of the material between two opposing surfaces — the jaws. Pennsylvania Crusher brand Jaw Crushers are available in both Double Toggle and Overhead Eccentric models.
A Toggle Crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism. The jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it travels downward until it is small enough to escape from the bottom opening.
Ribbed or a combination of these. The single and double toggle jaw crushers are constructed for heavy duty fabricated plates with reinforcing ribs throughout. Fixed and movable jaw faces are made up of manganese steel. The working principle of jaw crusher shown below in Figure 1 and the single and double toggle jaw crusher mechanism is.
Toggle jaw crusher mechanism. As a result of this analysis, a characteristic force transmission ratio, which may be regar-ded as a mechanical advantage of the mechanism, is derived. is ratio can be used as a criterion for the comparison of di erent jaw crusher mechanism designs, with a view to.
Purpose: To obtain equations that can be used to describe the motion of any given point in the swing jaw of a single toggle jaw crusher. Design/methodology/approach: The swing jaw drive mechanism.

A wide range of Double Toggle Jaw Crushers (300mm x 175mm to 1500mm x 1200mm) The design of Access Petrotec Jaw Crusher ensures crushing by pressure by positive gear pump for the bearing pitman and toggle mechanism, enables the crusher to run safely at relatively higher speeds.
“Computer Aided Design of Jaw crusher” 1.2 Double toggle blake type jaw crusher 4 1.3 Dodge Type Jaw crusher 5 1.4 Schematic Diagram of a jaw crusher 8 The mechanism of jaw crusher is based on the concept “crushing without rubbing”. Jaw crushers consist of.
Features of double toggle oil type jaw crusherProven ManufacturingThe design lies behind the machine design that proves the reason of the best performance, and the skilled craftsmanship that uses the design provides the proven manufacturing by delivering the best result to the toggle design, even for the smallest size crusher, distributes the load to different spares and protects.
Double-Toggle Jaw Crusher. Figure 4.2 is a sketch of a Dodge type of crusher. They are comparatively lower in capacity than the Blake crushers and are more commonly used in laboratories. 5.5.1 Gyratory crushers. The mechanism of crushing is considered similar to that of a jaw crusher.
Double Toggle Jaw Crusher. Specification: Contains big roller bearing in two sides. Large jet entrance for making easy to crush the input material in crushing chamber. Connected tab plates to swing jaw for keeping equilibrium of jaw & prevention from power wastage during go up & kick. Confident mechanism for increase lifetime & decrease the upkeeps.
The History Of Jaw Crusher. The first jaw crusher was invented by Eli Whitney Blake. It was named and patented the Blake crusher in 1858. In crusher, Blake employed a toggle which was the principal mechanism of the crusher. Today jaw crushers are used in.
Double toggle jaw crusher. 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.
Review Paper on Swing Jaw Plate in Jaw Crusher Machine 1Shaswat L Padalia P Patel,3 Mr.. on the mechanism used crushers are of three types namely Cone crusher, Jaw crusher and Impact crusher. It is cheaper and has less weight compare to a double toggle type jaw crusher. The function of the toggle(s) is to move the pivoted.
Mar 18, 2015 · Learn How A Jaw Crusher Works. by a cam or pitman mechanism, acting like a class II lever or a nutcracker. The volume or cavity between the two jaws is called the crushing chamber. The movement of the swing jaw can be quite small, since complete crushing is not performed in one stroke. In the double toggle jaw crushers, the oscillating.
A sectional view of a jaw crusher which incorporates the Blake double-toggle mechanism is shown below. The Blake crusher in common with all machines of the jaw family is built into a rectangular frame, at one end of which is located the crushing chamber; in fact, the end of the box-frame constitutes the stationary jaw.
