Crusher is a widely used gravel machine, which is mainly used in the crushing of granite, limestone, quartz and other stones. The crusher can crush the stone into fine particles by extrusion or bending, which is usually divided into fine crushing, medium crushing and coarse crushing.
Design and production of an indigenous roll crusher from locally available materials for low hardness rocks was carried out in this work. The throughput capacity of the machine was 1.43tonnes/hour. The theoretical efficiency of the double roll crusher when crushing limestone was 60% while that of kaolin was 80%.
FLS Double Roll Crushers are capable of impres-sively high throughput rates – up to 14,000 tph – thanks to the customised tooth and liner design and optimised installed …
Howto Size smooth Roll Crushers Adam Zanker Smooth roll crushers are widely used as secondary crushers, operating most effectively when set for size re-ductions in a ratio between 3 or 4 to I.
