Feb 17, 2017 According to this, if we now further crush down to diameter z the additional work done is Q 1z 1y, and the total work done in crushing from diameter x to diameter z Q 1y 1x Q 1z 1y, which Q 1z 1x, 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.

Working Principle of Metal Crusher The basic principle of metal crusher is impact of material by hammer beating. When the material enters into the crusher, it is suffered impact from the high speed rotary hammers, flap of the crushing chamber body and at the same time strike among materials. Thus material is grinded by lots of times.
