How Does a Rock Crusher Work? Sciencing

2017年4月24日  A rock crusher is a device used to crush rocks into smaller pieces, usually for gravel or some other road or building application. Most rock crushers have a hopper at the top -- a container which holds the rock above the crusher and uses gravity to feed it in. Alternately, rock crushers can use a belt drive to continuously transport the rock ...

Impact vs cone crushers: Which is more effective? - Quarry

2015年4月1日  The post-primary crushing sector is largely divided into impact crushers for the processing of softer stone and cone crushers for the processing of harder, more abrasive stone. The advantages of both machines are well known. The impact crusher, for example, has a higher co-efficient of reduction, produces crushed material with an optimal

A Detailed Overview of Cone Crushers and What You Need to
