Double Roll Crusher
A Double Roll Crusher is based on the principle of feeding the material to be crushed between two manganese steel cast rollers rotating in opposite directions, with their axes parallel to each other.
The gap setting between the rolls is very small, and hence the feed material is crushed while it passes through them. The central axis of one roll is fixed while the other is of floating design. The floating roll gives way to any uncrushable material that falls in the feed opening.
A double roll crusher may be categorised as SMOOTH / SMOOTH AND CORRUGATED / CORRUGATED double roll crusher depending on the corrugation on none, one or both rolls respectively.
