Three-roller Mill for Powder Coating

About Three-roller Mill for Powder Coating

　　Realize powder surface modification by changing inner vortex with three rotating rotors.

　　High speed friction spontaneous heat, Low investment and operation cost without any additional heating system.

　　We achieve the highest coverage or modification with minimal coating material andcost.

　　In polymer materials, composite materials such as plastics, rubber, adhesives, etc., non-metallic powders must be modified as a filler to enhance their compatibility with the matrix, dispersion, mechanical strength and overall performance.

　　The modifier can be selected from stearic acid or a coupling agent (titanate coupling agent, aluminate coupling agent, phosphate coupling agent, etc.).

　　Wideapplication, can achieve the desired activation effect on various inorganic mineral powders.

　　Dispersity of modifier is increased by means of dilution, emulsification and spray.

　　The material to be modified is fed into the coating machine, where the material will be mixed, dispersed and then coated by atomizing modifier sprayed by dosing pump and the the powder will be coated evenly and completely.

　　Control of system temperature and time is so regulated not only to meet the requirement for coating mechanism or modifier on technical conditions, but also to guaranteecoating sufficiency.

　　Ensure the adequacy of material coating by uniform feeding and coordination with the quantitative feeding of modifiers.

　　In conjunction of accessories ( depolymerizing machine or classifier), the product quality will be improved largely.

　　In conjunction of accessories ( depolymerizing machine or classifier), the product quality will be improved largely.

　　The whole system is easy to operate, high degree of automation, high efficiency, low cost.

　　Personalized solution for powder surface modification based on material properties and product use.

Working Principle

　　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.

Features

　　Mature process, low investment, suitable for stearic acid coating modification; Self friction heat generation, less auxiliary equipment; It is suitable for the modification of 325 ~ 1250 mesh powder.

Technical Data

　　Note:The production capacity is closely related to the particle size, specific gravity, hardness, moisture and other indicators of the raw materials. The above is only for selection reference.
