Introduction

    Modified powder machine / Mineral Powder Coating Machine is used for dispersing the powder surface modification and deposition process. It can not only improve the compatibility between inorganic mineral filler and organic polymers, but also can improve the interfacial bonding strength, to improve the amount of filled powder filler, reduce production costs, mainly used in the field of non-metallic mineral fillers or pigments such as plastics, rubber, adhesives and other modern polymer materials, polymer-based composite materials, functional materials and coatings industries.

    The end products are widely applied on powder modification in the field of high calcination, silica powder, heavy calcium carbonate, wollastonite, talc, light calcium, alumina, silica, magnesium oxide, magnesium hydroxide and the like. Mineral powder after modification not only can greatly improve the compatibility of inorganic mineral filler and organic polymer, but also improve the interface bonding force, enhance the mechanical strength of the material and other overall performance, greatly improve the powder filler filling volume, to reduce production costs at the same time to endowed special physical and chemical properties to the product.

    Modified powder machine / Mineral Powder Coating Machine has good surface modification effect for heavy, light calcium carbonate, talc, kaolin, silica, limestone, quartz powder, mica, silica, titanium dioxide, zinc oxide, aluminum oxide, agnesium hydroxide, barium sulfate, illite, pyrophyllite, tremolite and other powders. Mineral powders after modification, not only can greatly iprove the compatibility of the inorganic mineral filler and the organic polymer, improve boundary srface adhesion, make mecanical strength of the reinforcing material and overall performance, but also a substantial raise to the degree of filling amount of powder filler, reduce production costs while assigned the product some special physical and chemical properties.

Mill Structure

Modified powder machine/Mineral Powder Coating Machine to complete a surface treatment of powder by three modified cylinder which lies like triangle, dry powder and precisely metered agents entering into modified cylinder at the same time, with the high-speed rotation of the rotor, those powder and agents were fluidized decanter run; powder were collision, friction, shearing during rapid rotation with heat generated by rotor to deposition modified quickly.
