Vertical Sand Mill

Used mainly by the paint, ink & coating industries for size reduction and dispersing of pigments in liquids. Particle size reduction upto 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 of 3mm dia. The media is agitated by a shaft fitted with a number of impeller discs along its length. As the material moves upwards it is subjected to high hydraulic & shearing forces between the grinding media which results in fine grinding of the material. This material then passes through the screen which separates the media from the process material. All mills are povided with a jacket arrangement for cooling the material in the grinding chamber.
