Roll Crushers. Roll crushers are machines used to reduce the size of materials by compressing them between two rotating rollers. They are commonly used in the mining and construction industries to process materials such as coal, clay, and limestone. Roll crushers come in two varieties: smooth roll crushers and toothed roll crushers.
>Smooth Double Roll Crusher
Roll Crusher Working Principle: The working principle of a roll crusher is based on compression. The material is fed between the roll-cells, and the roll-cells rotate in opposite directions. As the roll-cells rotates, it compresses the feed material together, and eventually the material is crushed into smaller pieces.
