Structure and Function
● Hopper : materials enter into hopper from silo or bags. Humidity of feeding materials should be less than 0.5%.
● Conveying device : double screws and adjustable speed ensure the stability of material flow.
● Agent adding system with temperature control : automatic temperature control system, free setting of melting temperature, suitable for various modifying agents in both solid and liquid form.
● Main machine : consisting of 3 modifying rollers in triangle form, compact design, high efficiency and stable running.
● Cyclone dust collector : diffusion type.
● Impulse type bag dust collector : new generation pleat filter, with the advantage of little space, large filtration area, high dust removal efficiency and easy cleaning.

Working Principle
The powder surface treatment is mainly completed by means of three modifying rollers. The dry powder and dosed agent are put into the modifying rollers simultaneously. With high speed rotation, the power and agent is running in the form of fluidizing vortex. The modification is going on with the heat generated by high speed shearing, colliding and friction among the rotor, stator and the powder.
Working Features
★ Continuous operation, large capacity, suitable for industrialized production in various scale.
★ High efficiency and less consumption of modifying agent, high covering and active index of powder, energy saving.
★ Both modifying and dispersion function, suitable for any fine materials, special active effect for material with small proportion and dispersion function, suitable for any fine materials, special active effect for material with small proportion and big cubage weight like white carbon, mica powder and talcum powder.
★ Powder and agent mixing and running in high speed and vortex, high modifying efficiency, with little change of granulate shape.
★ Running in negative pressure working condition, air tight, no dust leakage, no pollution, good operation condition, low labor intensity.
★ Operating in heat and cold conditions, no additional heating or cooling system required, easy operation.
★ Independent fluid and non-fluid agent adding system for continuous, stable and evenly operation.
Evaluation Method of modified Powder Surface
● Active index
H=Weight of floating part in sample / total weight of sample.
● Measuring contact angle
● Surface strength (surface tension)
● Surface covering rate (diffusing reflection Fuliye divert spectrum method)
