Sand Mill

Sand mills are vertical bead mills which are used for particle size reduction and dispersing of pigments in liquids in the paint, ink & coating industries. Particle size reduction up-to 2 microns is possible in a single pass. The material to be processed is pumped from the bottom of the mill into the milling chamber which is filled with grinding media. The media is agitated by a shaft fitted with numerous discs along its length. As the material moves upwards it is subjected to high hydraulic & shearing forces which results in fine grinding of the material. The material then passes through the screen which separates the media from the mill base. Mills are jacketed to provide for efficient cooling of the mill base.
