Surface modification of mineral powders is an inevitable product of modern high-tech and new material development, widely used in non-metallic mineral fillers or pigments such as plastics, rubber, adhesives, and other modern polymer materials, polymer based composite materials, functional materials, coatings, and other industries. After modification, mineral powders can not only greatly improve the compatibility between inorganic mineral fillers and organic polymer materials, increase interfacial bonding strength, enhance the mechanical strength and comprehensive performance of materials, but also significantly increase the filling amount of powder fillers, reduce production costs, and endow certain special physical and chemical properties of products. However, the vast majority of ordinary non-metallic mineral materials have different interfacial properties and poor compatibility with organic polymer matrices. Direct or extensive filling can lead to a decrease in some mechanical properties of the material. Therefore, surface modification of inorganic mineral fillers is very important.

The unique modification chamber design of this machine combines modification and depolymerization functions, suitable for modifying various materials such as heavy and light calcium carbonate, various kaolin, talc, wollastonite, quartz powder, mica, white carbon black, titanium dioxide, zinc oxide, aluminum oxide, magnesium hydroxide, barium sulfate, illite, pyrophyllite, tremolite, etc., all of which have good surface modification effects.

1. The entire modified unit consists of the following components:

a、 Hopper: The material enters the hopper directly from the material warehouse (or packaging bag feeding), and the moisture content of the material should be less than 0.5%.

b 、 Feeding device: using twin-screw feeding, adjustable speed, can ensure the stability of material flow.

c、 Temperature control dosing system: temperature self-control, can set the melting temperature of the drug arbitrarily, suitable for various solid and liquid forms of modified drugs.

d、 Modified host: The modified host consists of three T-shaped modified cylinders, with a compact structure, high modification efficiency, and stable and reliable operation.

e、 Diffuse cyclone dust collector.

f、 Pulse type bag filter: using * * pleated filter cartridge, it has many advantages such as small footprint, large filtration area, high dust removal efficiency, and easy cleaning.

2. Characteristics:

a、 This unit is capable of continuous operation and production, with a large processing capacity, suitable for industrial production of various scales.

b、 The utilization rate of modified agents is high, the dosage is small, the powder coating rate and activation index are high, and the energy consumption is low.

c、 The equipment has both modification and dispersion functions, suitable for materials of various fineness, and has a unique modification and activation effect on materials with low false density and high density ratio, such as white carbon black, mica powder, talc powder, etc.

d、 The high-speed gas-solid phase vortex mixing operation of powder and agent has high modification efficiency and basically does not damage the original particle shape of the powder.

e、 Material negative pressure operation, good sealing, no dust leakage, basically no pollution, good operating environment, low labor intensity.

f、 Heating and cooling are completed in one machine, without the need for separate heating and cooling systems, simplifying operation.

g、 Independent fluid and non fluid dosing systems, continuous, stable, and uniform.

The surface treatment of the powder in this unit is mainly carried out using three finished product shaped modification cylinders, dried powder, and precisely measured reagents. At the same time, they enter the modification cylinder and run in a fluidized snail state with the high-speed rotation of the rotor. With the help of the heat generated by the collision, friction, shearing, and high-speed rotation of the rotor, the powder is rapidly modified into a film.
