Brief introduction of Powder Surface Coating Machine:
The mineral powder surface modifying, widely used in the fields of non-metal stuffing or pigment like plastic, rubber, adhesive, macromolecule materials, high polymer composite, functional materials and dope industries, is an outcome of the development of new and high technology nowadays. It can not only improve the compatibility of both non-organic mineral stuff and organic high polymer, enhance binding force of interfaces, rise the mechanical strength and comprehensive ability, but also increase the stuffing ability of powder, save product cost and add special physical and chemical property to the product to some extent. For resolving the above-mentioned problem in production, this high efficiency equipment powder surface modifying machine is recommended by our company as a result of hard research work.
Application of Powder Surface Coating Machine:
With special chamber design and the function of modification and depolymerization, the machine is applicable to modifying various materials. It can reach excellent surface modifications for such materials as heavy / light calcium carbonate，kaoline, talcum，wollastonite, mica, white carbon black, zinc oxide，alumina, silicon powder, graphite, magnesium-hydroxide bariumcarb，illite claystone and pyrophylite, hexagonite and et
Structure and Special feature of Powder Surface Coating Machine
The machine is made of following parts:
a. Hopper: materials enter into hopper from silo or bags. Humidity of feeding materials should be less than 0.5%
b. Conveying device: With double screws and adjustable speed to ensure the stability of material flow
c. Agent adding system with temperature control: Automatic Temp. Control, free setting of melting temperature, suitable for various modifying agents in both solid and liquid form.
d. Main machine: Consisting of 3 modifying rollers in triangle form, compact design, high efficiency and stable running.
e. Cyclone dust collector: Diffusion type
f. Impulse type bag dust collector: New generation pleat filter, with the advantage of little space, large filtration area, high dust removal efficiency and easily cleaning.
Working Principle of Powder Surface Coating Machine:
The powder surface treatment is completed mainly by means of three modifying rollers. The dry powder and dosed agent are put into modifying rollers simultaneously. With high speed rotation, the materials and agent is running in the form of fluidizing vortex. The modification is completed with the heat generated by high speed shearing, colliding and friction among the rotor, stator and the powder.
