Roll crusher is used in the process of primary, medium and fine crushing as well as rough grinding. The single-roll crusher and tooth double-roll crusher manufactured in China is the classic primary grinder with the maximum feed granularity up to 800-1000mm. While the WMS roll crusher manufactured in Germany is used for fine crushing and rough grinding work.
Tooth and belt groove roll crusher normally used for dry primary crushing or medium crushing for soft and medium hardness materials. Plain roll crusher used for fine crushing and rough grinding stiffness materials.
Less over crushing granularity is not only the primary advantage of roll crusher, but also the important factor to choose the crusher besides the technical features such as production output, power consumption, working reliability, machine weigh, dimension, etc.
Single-roll crusher uses shear force together with pressure and splitting to crush. For some special materials such as sponge drill or coke, it can crush effectively with variety of teeth shape and layout to adapt the demand of material properties and products granularity.
