Business efficiency requires that you use highly efficient production methods for powder coatings. Such processes minimize production losses and improve work efficiency. There are a number of factors concerning your grinding mill that influence the quality of powder coatings. These include:
Particle size distribution
A narrow particle size distribution with a sharp, well-defined top cut and fine particles in low amount is necessary for high product quality. The material properties of the powder coatings influence the produced particle size of distribution and by the process technology of the powder coatings grinding mill.
Design and efficiency of the grinding system
The width of the particle size distribution is also depended on the design and efficiency of the grinding mill system.
Dimensions of the mill- This is important in avoiding overmilling.
Type of grinding elements- This helps in achieving a high grinding intensity, highly efficient classification and an optimized airflow conditions.
The production of powder coating involves a few processes:
- Grinding of the powder coating chips inside the impact classifier mill
- Separation of the powder coatings from the airflow.
A dosing rotary airlock is used to feed the chips out of a vessel which are then transported by airflow into the ICM which in turn grinds the powder. The ICM grinds the powder with hammers which have a tip speed of up to 130m/s. The ground particles are transported to an impeller wheel classifier using an internal circuit. Internal classification achieves a short residence time inside the powder coating grinding mill and avoids overmilling of the product.
Particles of the desired size are allowed to pass while coarse particles are rejected and transported again into the grinding zone. Final product of the desired particle size will produce a narrow particle size distribution. Classifier Milling Systems offers highly efficient grinding mill production of powder coatings to its clients.
