A gyratory crusher has a mantle that rotates within a concave bowl while a cone crusher has a mantle that rotates within a bowl shaped concave This design allows for a larger feed size and a higher capacity for both types of crushers but gyratory crushers are typically designed for high capacity crushing whereas cone crushers are intended
This cone crusher has a hydraulically supported main shaft that is supported at both ends Sandvik CH660 has a robust crusher design adjustable eccentric throw and a constant intake opening This crusher is suitable for a high capacity secondary application or a high reduction tertiary or pebble crushing application

A well graded feed is generally though to be 90 100% passing the closed side feed opening 40 60% passing the midpoint and 0 10% passing the closed side setting One thing you should never do is place a new concave liner in a crusher with a worn mantle or place a new mantle in a crusher with a concave liner Why
Wearing parts in the gyratory crusher may be either chilled cast iron or manganese steel depending on the character of the material to be crushed and the particular class of service for which the machine is intended Standard crushers in the small and medium sizes are customarily fitted with chilled iron head and concaves for crushing soft and medium

Jaw Crusher 500 mm to 800 mm Reduced to about 125 mm to 150 mm Large chunks of material are fed into the jaw crusher where strong compressive forces break them down Secondary Crushing To refine the size of the materials from the primary crushing stage Cone Crusher Impact Crusher Usually between 125 mm and 150 mm Further reduced to 20

That crusher must be capable to reduce the size of even the lastest rocks it is fed To secure the capacities specified all feed to crushers should be smaller than the feed opening of the crusher in at least one dimension The crusher discharge P80 product size needs to remain less than 1/3 of the related conveyor belt width

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 The parameter study is evaluated using mechanical and geometrical tests for
The first step in the mining and processing of nearly any mineral ore is comminution Since the oil embargo of 1979 the mining companies have been striving to reduce energy consumption and costs The first serious step was the introduction of in pit crushing in the early 1980s With in pit crushing accepted as a standard design mode the energy saving emphasis turned to
M i = work index related to the breakage property of an ore kW h/tonne ; for grinding from the product of the final stage of crushing to a P 80 of 750 μm coarse particles the index is labelled M ia and for size reduction from 750 μm to the final product P 80 normally reached by conventional ball mills fine particles it is labelled M conventional crushing M
