In many applications, coarse and non-uniform feed material is crushed or pelleted in a first step with a primary crusher. The distribution of particle sizes is dictated thereby by the combination of rotor speed and screen size. The multi-purpose crusher MPC 150 offers three common grinding processes in module form that can be fitted onto a basic unit:
- Conical mill for soft to medium-hard materials
- Flake crusher for brittle materials that crush easily
- Hammer mill for solid materials that are difficult to crush
These modules for all three processes can be exchanged with only one single tool and thus correspondingly quickly. In addition, the modules are very easy to dismantle and clean – there are no threads or screw heads installed in the sections in contact with the product.
Dependent on the grinding process, the size of available screens ranges between 0.3 and 20 mm. Especially in the extremely fine range, these screens offer application possibilities that were barely possible before. As a function of the mill type, the peripheral speeds range between 1 and 60 m/s. Most applications are operated in the range between 1 and 20 m/s.
