The Disadvantage of Double Roll Crusher

One disadvantage of the double roll is that one set of rollers delivers product to the conveyor in the opposite direction to the belt travel. A curved chute can be fitted to reduce the effect but if the feed material is sticky or contains a percentage of clay then a build up of material in the chute can occur leading to clogging. The sticky material can also form boulders in the dead space between the rollers which ‘ride’ on them and become such a size that when eventually discharged cause damage to the conveyor belts.

If you have a higher demand for crushing effect, impact crusher and cone crusher is a good choice.
