Working Principle and Equipment type features
Drying and dispersing machine, also known as Multi-Rotor Dryer Mill, is jointly designed by our German technical experts and British technical experts. It can’t only achieve high-efficiency grinding, but also has excellent drying, dispersing and depolymerization, and modification functions. Its vertical shaft is equipped with multi-layer rotors, and max up to 10 layers of rotors. There are multiple evenly distributed blades on each rotor layer, slots formed by adjacent blades, like a honeycomb. The largest mill has 1600 slots. When the rotor rotates at a high speed, the airflow forms a turbulent flow in the slot. The mill liner is usually corrugated or multi-toothed, which promotes the formation of turbulent flow, and also enhances the grinding force, shearing force and impact force.
Advantage
- The rotor speed can be adjusted,up to 160m/s.
- The hot air temperature of drying design, up to 450℃.
- Set modifier injection nozzle on the mill cavity.
- The built-in classifying design can better control the particle size of the product.
- Strong shearing force, suitable for crushing tough and fibrous materials.
- Fast crushing speed, suitable for crushing heat-sensitive materials, and a cooling process system can be added for materials with extremely low melting points.
- According to different project needs, we have different blade designs and liner designs.
- Main material can be carbon steel, wear-resistant steel, stainless steel.
- Blade material can choose wear-resistant steel, stainless steel, tungsten carbide.
- Lining plate material can choose carbon steel, wear-resistant steel, stainless steel, alumina ceramics.
