An important point often overlooked by plant design and application people is that the crusher must have an adequate amount of evenly distributed feed. Figure 8 shows the effect of poor and good feed distribution. If the feed is correct, the crusher will have maximum produc- tivity (highest average crushing force) for minimum mechanical stress.
