Product Introduction:
Powder classifier is a device that divides particle groups into two or more particle size grades based on the principle that solid particles have different settling velocities in the medium due to differences in particle size, density, etc.
Using air as the medium, the sedimentation speed and movement trajectory are different under gravity and air medium resistance to classify.

Aluminum Powder Classifier Milling system is an innovative device that integrates dry milling and dynamic classification of materials.
Ball mill is the key equipment for crushing materials after they are broken. The cylinder is generally made of welded steel plates, closed at both ends with end covers, and the inner wall of the cylinder is inlaid with wear-resistant lining to prevent the cylinder from wear.
The explosion-proof flap valve is a pressure differential self-operated dust explosion isolation valve that does not require external electrical equipment.
