Internal Hot Air With Suitable Temperature Coating Machine For Better Modification
Coating Machine with Internal hot air for better modificaiton
In the powder modification process, most of the traditional gravity modification equipment adopts electric heating or oil heating to promote the modification work. The kind of coating machine does not require external heating. The heat required for powder modification comes from two aspects: one is the heat generated when the air collides. The high-speed rotor in the cylinder drives the air for high-speed movement, and the collision and friction of the air will generate heat.
When the modifier is empty without powder, the air temperature in the cylinder will increase with the operation of the coating machine. The temperature of the air measured at the discharge port can reach about 60 to 65℃. The second is the heat generated by the collision, friction, and shearing caused by the mutual motion of the rotor, stator, and powder.
The powder mixes, breaks up, collides, and rubs in the cylinder at high speed to release a lot of heat. During the normal production process of the equipment, the temperature of the material outlet is between 90 and 130℃, which can meet the heat required for powder modification . The modification temperature varies depending on the powder density, fineness, particle shape, water content, etc. This kind of coating machine does not need external heating in the powder modification process, which can save auxiliary equipment such as external heating, simplify the production process, and reduce production costs. The direct cost of powder modification by this coating machine is generally about 20% lower than that of traditional gravity modification equipment.
Usage of Coating Machine:
Coating machine is used to modify the surface of inorganic power to improve the physical and chemical properties of its surface, and to reinforce compatibility and dispersion with organic polymers or resins, and to improve the mechanical strength and comprehensive performance of materials. Coating machine can be used for the following powder(325-6000mesh) modification: heavy calcium carbonate, light calcium carbonate, kaolin, talc, fly ash, nitrogen oxide, sulfate, zeolite and etc.. The coating rate is more than 96%. And it also features less modifying additives for per ton power and no cohesiveness between powders. And after coating, the powder size will not become bigger. And this coating machine can also be used with different ultrafine grinding mill.
Features of Coating Machine:
1. 96-99% of the surface of all powder particles can be coated with modifier ( with special spray technology)
