Multi-functional Rotor Mill

Combining functions of drying, dispersing and modifying Combining functions of drying, dispersing and modifying

The multi-functional rotor mill is a powerful mechanical mill. It features multiple rotors attached to a vertical shaft, along with a multi-layer, grinding blade head that provides high shearing and scattering forces. Furthermore, it has the ability to be connected to a hot air source, granting it the capability to carry out the tasks of drying, dispersing, and even modifying materials.

When operating at high speeds, the mill creates a powerful airflow, through which the agglomerated powder particles are trapped in a special-designed stator. High pressure and speed wind generate a strong vortex, generating shear, friction, and centrifugal forces which then quickly break down the material into individual particles, or crystal particles close to their natural size.

Advantages Integration of the drying and grinding processes ensures high efficiency while keeping operation costs low.
Designed to withstand temperatures up to 400℃, with the bearing designed with heat insulation.
The grinding block and lining are changeable, and a variety of materials can be used depending on the type of material being processed.
Built-in classifier wheel optional, allowing coarse materials to be milled circularly.
External heated air optional, allowing drying and grinding process operated at the same time. Powered by high-speed rotors, materials in the grinding chamber are surrounded by hot air resulting in a large area for heat exchange. This makes moisture evaporate efficiently and the heat source is more efficiently utilized, hence achieving an energy saving of 30-50% as compared to traditional drying methods. Technical Parameters
