The double-toothed roll crusher is a crushing device operating on the principles of extrusion and shearing. Its core structure consists of two counter-rotating toothed rolls. Widely applied in coal, mining, building materials and other industries. It is specially designed for the primary and secondary crushing of materials with medium hardness or below. The wear-resistant teeth distributed on the surface of the rolls can be customized according to material characteristics. Through the relative rotation of the toothed rolls, materials entering the crushing chamber are firmly gripped. Then crushed by extrusion and shearing, resulting in uniformly sized crushed products with minimal over-crushing.

Compared with traditional crushers, it boasts distinct advantages: compact structure, small floor space, and easy installation and maintenance; stable operation, low energy consumption, and high production efficiency; strong adaptability with no easy clogging when handling viscous materials. In the coal industry, it can crush raw coal to ensure the smooth progress of subsequent separation processes. In the mining sector, it is capable of processing materials such as limestone and shale, providing qualified aggregates for subsequent production procedures.

With technological upgrades, the new-type double-toothed roll crusher is equipped with an intelligent control system, which can adjust the rotation speed and spacing of the toothed rolls in real time, accurately control the discharge particle size, further improving operational flexibility and intelligence, and making it a key piece of equipment in modern crushing production lines.
