Feb 17, 2017 According to this, if we now further crush down to diameter z the additional work done is Q (1/z 1/y), and the total work done in crushing from diameter x to diameter z Q (1/y 1/x) Q (1/z 1/y), which Q (1/z 1/x), the same as if the crushing were all done in one operation. To make the computation, then, it is necessary to determine the reciprocal of the diameter of the particle.
The crushing power of the jaw crushers depends on the size of the chamber. The bigger the chamber, the more powerful the jaw crusher. The crushing process can be basically explained as a process where the materials are sandwiched between two jaw plates. The movable jaw plates squeeze and crush the materials into several small pieces.
