Hello Friends,
Roll crushers are also one of the secondary or tertiary crushers. This crusher consists of,a heavy cast iron frame equipped with two counter rotating rollers mounted on a separate horizontal shaft. The crushed rock from the primary crusher is fed through the gap between the two rollers for crushing further. Usually one roller has a fixed axis while the other can be adjusted to give the required setting. This crusher is compact, light weight and low in cost.
