General introduction to Honeycomb Mill for powder coating

  Principle and characteristics: when the equipment is running at high speed, it drives the strong air flow, so that the agglomerated powder particles stay in the stator of the equipment, and the stator is designed as a special groove. The strong vortices formed by wind pressure and wind speed will produce shear force, friction force and centrifugal force, which can quickly break the materials into single particles and reduce them to the original particle size or natural crystal particles.

  Maximum capacity: 4.5t/h

Advantages of Honeycomb Mill for powder coating


  It integrates drying and crushing functions, with high efficiency and low operation cost;

  It can withstand high temperature of 400 ℃, and the bearing adopts heat insulation design;

  The grinding block and grinding lining can be replaced, and the grinding block of different materials can be selected according to different materials;

  The internal grading wheel can be selected to grind coarse materials circularly in the mill;

  It can be connected with external heating air and realize drying and dispersing functions at the same time. Under the action of high-speed rotor, materials and hot air can be fully contacted in the crushing and dispersing area. The heat exchange area is large, and the water can be taken away effectively. The heat source can be used more efficiently, saving energy by 30% – 50% compared with traditional drying.

Working principle of Honeycomb Mill for powder coating

  The material enters the Ulm pulverizer through the quantitative feeding system, and the 200 ~ 300 ℃ hot air enters through the secondary air outlet. In the dispersing chamber, the turbulent collision between the materials is used to fully disperse and form a full heat exchange with the hot air. During the rising process of the material, it is continuously dried, and the dried water is taken away with the hot air. The dried material is controlled by the air classifier to meet the upper limit requirements of the final product, The qualified air enters the cyclone collector for collection with the air flow, the dust is filtered by the pulse dust collector, and the clean hot air enters the dispersing system through the return air system, so as to make full use of it and improve the thermal efficiency.
