70 80 90tph capacity PF-1010 PF-1210 models impact crusher machine for limestone dolomite rock in Africa

China Ascend impact crusher machine

Impact crushers are ideal for crushing medium hard brittle materials of coarse, secondary and fine crushing stages, such as limestone, dolomite, sandstone, graphite, rock salt, granite and basalt. Impact crusher have high reduction ratio, unequaled output, uniform production size, compact process, simple construction, easy operation and maintenance.

Working Principle

The feed enters the primary crushing chamber and meets the breaker bars which impel the feed against the front breaker plate. This action and the collision of material against new feed results in impact reduction. Material is sufficiently reduced in the primary chamber and passed by the front breaker plate, entering the secondary chamber for final reduction. Breaker plates are shaft suspended at the front and from a spindle in the rear, allowing for continuous gap adjustment as wear progresses and assuring superior product control.
