The jaw crusher line is designed for the motor sizes listed in RPG and technical specifications. This means that for harder materials, the crusher will have to be operated at larger settings to avoid overload of drive and/or motor. Using oversized motors will lead to radically shorter crusher life and various mechanical problems.

The jaw crusher discharge opening is the distance from the valley between corrugations on one jaw to the top of the mating corrugation on the other jaw. The crusher discharge opening governs the size of finished material produced by the crusher. Measuring Discharge Opening: Measure distance at bottom of jaws at the point of the …
equation of jaw crusher is built to get mathematical expression of the stroke feature value. Taking the PEF600x900 jaw crusher as an example and choosing the stroke feature value of outlet as an objective function, the optimization model is built. Then based on the model the component sizes are obtained by random
The specific energy consumption at the motor input can be predicted using Bond's equation: E = 10 × CWi × (P80 – ½ - F80 –½). where CWi is your work index, F80 is the 80% passing size of the feed measured in µm, and P80 is the 80% passing size of the product measured in µm. E is the specific energy in kWh/tonne. Very important -- there …
Jaw crushers use compressive force to break down materials. The crushing chamber has a fixed jaw and a moving jaw, says Price. The moving jaw is attached to a pitman that moves back and forth creating a swinging motion. Jaw crushers are generally more affordable and best suited for hard rock and an initial reduction in size.

A Jaw Crusher is sized so that the maximum feed size is 80% of the gape and width openings. The gape is the measurement between the two jaw dies, while the width is the measurement between the two side plates. For example, if the maximum feed size is 29"x49", the crusher gape would be 32" and the width would be 54".
