fine grinding particles

A Practical Guide To Powder Coating Particle Size

Jan 30, 2017 · An excessive amount of fine particles can also contribute to application guns spitting or sputtering because fine particles can be fluidized more easily than standard particles. During the grinding process, powder manufacturers have suction hoses above the grinders to catch a lot of these fine particles that would not otherwise be sifted out.

Classifier performance during dynamic fine grinding in ...

Dry grinding of particles to sizes below 10 µm can be realized in fluidized bed opposed jet mills. In these mills the energy for comminution is supplied by pressurized gas, which is introduced through focused nozzles. The gas transports the material towards an internal classifier, which separates the fines from the coarse material.
