The crusher head is at the moment in the close-side position. Crusher Working Principle. As the head recedes on its opening stroke, the body of material moves downward; until, at the end of the stroke, the plane has moved to position "1.". Note that the length of line "1″ from concave to open-side head position, is the same as that of ...

Cone crushers and jaw crushers both work by compression, reducing materials by squeezing them until they break apart. The benefit that cone crushers offer over jaw crushers is their ability to output a more cubical product similar to impact crushers. Cone crushers have traditionally been used as secondary and sometimes tertiary crushing ...

4.4 Jaw Crusher Capacity Estimation. The capacity of jaw crushers is a measure of the mass or volume of crushed material produced in unit time of operation. The capacity is primarily a function of: 1. crusher design characteristics such as width and depth of the crushing chamber, 2. open and closed side settings, 3.
