Mechanics of the jaw crusher

Abstract
When preparing ores for beneficiation, as well as in the construction of various structures are widely used machines for crushing large pieces of rocks. Among them a prominent place is occupied by the so-called jaw crushers, in which pieces of rocks are crushed by periodically pressing on them two rectangular jaws - swinging and stationary.For the normal operation of such a crusher is necessary that when pressing the jaws on a piece of ore, the latter is not pushed upward by them, but wedged between them. This is not possible at any angle between the jaws, but only at angles smaller than some of the largest angle.
