hammers was used to avoid the rotor or the hammers from getting stocked in case a hammer comes in contact with a material it cannot break at first impact. Design theories and Calculations Determination of Shaft Speed To calculate the shaft speed the following parameters are used. 1 2 2 1 N N D D Spolt, 1988 (1) Where N 1

In the EV crusher, however, the horizontal feed system accepts coarse feed blocks because it incorporates one or two shock absorbing inlet rollers. The inlet rollers accurately control the feed to the crusher and ensure a smooth and even flow of material. Whether one or two inlet rollers are used depends on the method of feeding the crusher.
