Experimental Study on the Crushing Process of Granular Layer

Abstract:

In order to make clear the effect of material on the vibration crusher which is a rigid-loose coupling dynamics system, a crushing experiment of limestone granules was made. The limestone granules were restricted in a rigid metal containers, and they were crushed by the pressure from the press. The constitutive relation-nonlinear hysteresis of granules in the crushing process is gained. The effect of the maximum pressure and the granular layer thickness on the constitutive relation and granule size distribution is obtained. The relation between energy absorption and crushing ratio is acquired. This experiment provides some theoretical support for the design of new vibration crusher.
