Any kind of irregularity in the feed whether from segregated feed, a misaligned feeder, or blockages or packing in the chamber can cause performance to drop by up to 30%. uneven distribution of material in the chamber means that the hydroset the mechanism that exerts an upward force on the mantle cannot maintain even pressure.

this is why it is vitally important that the feed arrangement to an impact crusher ensures an even distribution of feed material across the full width of the rotor. this will allow for even distribution of energy into the feed material and uniform wear patterns, ensuring consistent product gradation and power consumption.

process optimization. 1. crusher design evolution. compression cone crusher designs today have evolved from the simple cone crusher first developed in the mid-1920s by edgar b. symons, to the modern high performance crushers. early crushers used springs for tramp iron protection and were manually adjusted.

the crusher and feed parameters used are closed side setting (css), speed, feed rate and feed gradation. this paper presents a parameter study investigating the effect of feed and jaw crusher parameters on the quality of aggregates produced from single-stage crushing.

gradations of cone feed and crusher discharge must be monitored as a crushing/reduction performance indicator and as a liner wear indicator. this should be done at least once a month, and more often if required at the site. daily inspections below the crusher should be made to ensure no bridging, plugging or foreign material are under the crusher.

armed with accurate information, the manufacturer can customize the screen setup for maximum performance. for example, with a known feed gradation, the manufacturer can analyze the loading on each deck. if a deck has a heavier depth-of-bed ratio relative to the opening, that deck may be specified at a steeper angle than an accompanying deck.
