Special Modification Chamber Structure of Coating Machine

The good dispersion modification effect of coating machine is based on its unique modification cavity design. The so-called three-cylinder continuous powder surface coating machine is actually named as three modified cylinders arranged in a zigzag shape, not a single three-cylinder series. Each modified cylinder of the coating machine is equipped with a high-speed running rotor and a fixed stator. The linear speed of the rotor is 75-86m/s. The outlet of No.3 modified cylinder is connected with negative pressure induced draft fan. When working, the high-speed rotor and induced draft fan of the coating machine can form several working areas in the three tubes arranged in a zigzag pattern.

It is these areas that play the most crucial role in achieving the best dispersion modification effect during powder modification. The powder is conveyed by the adjustable speed twin screw conveyor, the modifier is pumped in by the metering pump, and enters the negative pressure dispersion area of the modified cylinder No. 1, under the action of suction negative pressure in the feed port, the material and the agent are quickly dispersed or atomized to form air-solid fluidized mixture. The powder and agent are preliminarily mixed in this area.

After the mixture is broken up by the high-speed rotor of the coating machine in the breaking area, it enters the positive pressure collision area at the junction of No. 1 and No. 2 barrels, and the powder undergoes collision mixing modification. The coating machine modification mainly starts from this positive pressure modification area. Then enter the negative pressure dispersion area at the junction of No. 2 and No. 3 cylinders, atomize and disperse again, and then be sucked away from the discharge port by the negative pressure fan after being broken up, enter the cyclone dust collection and bag dust collection system for product collection.

In this process, the powder and the modified agent were fully dispersed and mixed many times, creating good conditions for the modification work. It is this mandatory mixing, dispersing, and depolymerizing that whether it is coarse powder, fine powder, ultrafine powder, nano powder, or whether the crystal form is granular, needle, flake, or spindle, it can make powder materials It is not disturbed by its size, crystal shape, bulk density and other factors, so as to obtain good modification and dispersion effects.

Main Components of Coating Machine:

Non-metallic mineral powder coating machine includes the following parts: raw material silo, pharmaceutical barrel, screw feeder, pharmaceutical metering and filling system, modification machine host, cyclone collector, pulse dust collector, induced draft fan, electric control system, etc. Partly composed.

The coating machine is composed of three shaped modification cylinders. The dried powder and the precisely metered modifier enter the modification cylinder at the same time. The main motor drives the high-speed rotating rotor to make the material flow as a snail, And the heat generated by relatively high-speed shearing, collision and friction with the stator installed on the reforming cylinder rapidly forms a film for modification.

Technical Advantages of Coating Machine:

1. Good dispersion of powder and surface modifier, uniform coating of particle surface, less amount of modifier; especially suitable for surface modification of ultra-fine powder.
2. The coating machine can run continuously for production with large processing capacity, which is suitable for industrial production of various scales.
3. The usage rate of the modified agent is high, the dosage is small, the powder coating rate and activation index are high, and the energy consumption is low.
