Sand Mill

These Sand Mill Machine are used mainly by the paint, ink and coating industries for size reduction and dispersing of pigments in liquids. The particle size reduction up to 2 micron 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 and shearing forces between the grinding media, which results in fine grinding of the material. This material then passes through the screen that separates the media from the process material. All sand mills are provided with a jacket arrangement for cooling the material in the grinding chamber.
