Product details
Harder materials can be crushed by machines called high pressure roll crushers. Wood and pipes with thick walls and tiny volumes are two examples.
Rolls for High Pressure Grinding High Pressure Roll Crushers use compression to crush material, as opposed to standard crushers that rely on gravity or a mix of gravity and pressure. The material is crushed between two enormous rollers as they rotate in opposite directions, producing this force.
