Three-roller Mill for Powder Coating

The relative motion of three rotors can change the effect of cyclone and eddy current to realize the coating of powder surface. Without heating device, it has the advantages of low investment and low operation cost.

• Realize powder surface modification by changing inner vortex with three rotating rotors.
• Mature technology, low investment, suitable for stearic acid coating.
• Self-friction generates heat, no heating device is needed, less auxiliary machine, and low operating cost.
• Suitable for powder coatings of 325~1250 mesh.
• Power range: 11kW~225kW; Maximum output: 6t/h.
• Disadvantages:
• The air volume is small, the dispersibility is poor, especially the fine powder, and the amount of modifier is large.
• Self-friction heat generation is easily affected by environmental factors, and the modification temperature is poorly controllable.
• There is a dead zone and the coating rate is low.

Note: The production capacity is closely related to the particle size, specific gravity, hardness, moisture and other indicators of the raw materials. The above parameters are for reference only, please consult our engineers for details.
