325-6000 Mesh Powder 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.
The Purpose of Powder Modification
Powder surface modification is to use physical or chemical or
mechanical methods to do surface modification. According
application requirements, the physical and chemical properties of
the powder surface can be purposefully changed, such as surface
composition, structure and functional group, surface energy,
surface wettability, and electrical properties. The coated powder
with these features can meet the need of development in the new
material and new production techniques.
Special Features of Coating Machine
1. 100% of the surface of all powder particles can be coated with
modifier ( with special spray technology)
- Increase the powder temperature with heating regulation
- No leakage of dust; auto control of material feeding by PLC system;
easy operation;
- Continuous production, higher productivity; Running smoothly; less
power consumption
- Independent liquid and non-liquid dosing system
- Higher powder coating rate and activated rate
This equipment consists of 1. powder feeding device 2. modifier
metering device 3. Spraying device 4. main coating machine 5.
pneumatic system 6. pulse-jet collector 7.e lectric control cabinet
Working Principle of Coating Machine:
There are 3 mixing and scattering device in the coating machine.
When the machine works, the 3 devices rotate in a high speed to mix
powder and modifier and then scatter the powder. The powder and
modifier go through the 3 devices one by one. At the same time, the
modifier is being sprayed in the spraying room under the control of
metering pump, which will be fully mixed with modifier. In the
coating machine chamber, the powder and modifier are further
contacted and mixed by impacting, sheering and colliding between
powder in the high speed mixing chamber. The coating machine always
stays within a stable working temperature range to avoid change and
invalidity of modifier.
