were the most common choice crushers, but in recent years impact crushers are more widely used. these crushers also are sometimes used as primary crushers for fine-grained gravel deposits. the cone crusher (a compression type) simply crushes the aggregate between the oscillating cone and the crusher wa ll (figure 5-9). clearance settings on
cone crushers were originally designed and developed by symons around 1920 and therefore are often described as symons cone crushers. as the mechanisms of crushing in these crushers are similar to gyratory crushers their designs are similar, but in this case the spindle is supported at the bottom of the gyrating cone instead of being suspended as in larger gyratory crushers.
cone crushers. a cone crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at the lowest point.
