A roll crusher, also known as a double roll crusher, is a type of compression machine used to crush hard materials. It consists of two large metal rolls that rotate in opposite directions. The material is fed into the gap between the rolls and is crushed by the compressive forces exerted by the rotating rolls.

The DRC-Double roll crusher is designed in such a way that the rollers can be reversed from standstill with extremely high starting torques. Foreign objects that cannot be crushed are automatically released from the crushing chamber. This is done with the help of the hydraulic gap adjustment, which can open and close the crushing gap fast.
A discrete element method (DEM) model of the crushing process of a toothed double-roll crusher (TDRC) is established using the bonded particle model. DEM results and experimental data are compared quantitatively and a relatively good agreement is observed. The effects of rotation speed and structure of crushing rolls on the …
The top stage of the Quad Roll crusher is essentially made up of a double roll crusher, which is designed with the appropriate diameter rolls and tooth configuration to readily grab the incoming feed material. This stage is designed to reduce larger feed sizes at a 4:1 ratio before feeding directly to the secondary stage.
