Due to its unique operating principle, the roll crusher boasts several advantages such as high capacity, low over-crushing rate, excellent spatial adaptability, low dynamic load to foundation, and easy maintenance. It is one of the most widely used equipment in crushing medium to low hardness materials in industries like mining and aggregate processing. Diverse types of profiles and installation features of cutting tooth or teeth plates are therefore designed for adapting various double roll crusher applications.

For primary crushing, where the feed size could be up to 1.5~2m, rollers typically feature teeth ring or pick type teeth. For secondary and tertiary stage crushing with feed sizes normally below 400mm and 100mm respectively, the types of crushing teeth vary according to the particle size of the product, including teeth plates, teeth rings, and roller shells. GESION provides superior wear-resistant solutions for toothed parts based on different application conditions and material characteristics.
