Crusher Types Jaw Crushers. Jaw crushers operate by squeezing rock between two surfaces, one of which opens and closes like a jaw. Rock enters the jaw crusher from the top. Pieces of rock, that are larger than the opening at the bottom of the jaw, lodge between the two metal plates of the jaw.
The 48 by 42-inch jaw crusher and smaller sizes are force-fed by an automatic high-pressure lubricator to the swing jaw, pitman, and main bearings as illustrated in Figure 1. A motor-driven pump forces the lubricant through pressure buildup cylinders and out to distributors which dispense a precise amount to each of the points on the bearings.

These crushers use overhead action and corrugated jaw plates to force-feed material and avoid back-flow or "pop-out" of particles that occurs on units with smooth jaw plates. Particle sizes to minus 0.25in (6.4mm) are set via the handwheel adjustment of a single toggle.
Jaw crushers are generally installed on top of the concrete foundations. Take into consideration of the weight of jaw crusher, the tough working conditions and the high inertia forces generated by the machine during operation, which may cause the slight vibration of foundation and machine system; therefore, the foundation of the jaw crusher should be separated from the foundation of the workshop.
Based on the analysis of the liner movement and the crushing parameters, the normal pressure on the liner is adopted to describe the crushing force. A small experimental jaw crusher is used in the experiments, in which strain gauges and the multi-channel data collecting method are employed. With the measured results of the compressing force on the liner, the research on crushing force in jaw ...

Applying the crushing force by rolling the nut breaks flats and gives a product that is more "cubic" than the jaw crusher. – The largest-scale equipment can treat a flow with the magnitude of 4,000 tonne.h − 1. – With a production rate and flow that are equal, the power consumed by …
Jaw crusher • Feed is admitted between two jaws, which are open at the top like V • One of the jaws is fixed and vertical, while the other is the swinging jaw • This jaw reciprocates in a horizontal plane and makes the angle of 20-30° with the fixed jaw • Movable jaw is operated by an eccentric unit so as to impart great compressive force
The moving jaw swings toward the fixed jaw in the forward stroke, material is crushed, and discharge takes place during the backward or freeing stroke. The jaw crusher pictured below can be used to crush items from large objects such as demolition debris or broken concrete to smaller objects such as asphalt or river rock. Gyratory Crushers
cone crusher crushing force. Analysis of the Single Toggle Jaw Crusher Force. This paper sets out to perform a static force analysis of the single toggle jaw crusher mechanism and to obtain the force transmission characteristics of the mechanism In order to obtain force transmission metrics that are characteristic of the structure of the mechanism such influences as friction dead weight and ...
Dynamic forces that arise during the operation of jaw crushers are due to the presence of a gap in the kinematic pairing of the links (journals and bearing lining) and discrete speed values of the relative movement of the links inside the clearances of plain bearings.
