The Working Principle Of Sand Mill

Sand mill: Sand mill is also called bead mill. This machine is mainly used for wet grinding of chemical liquid products. According to the performance, it can be roughly divided into vertical sand mill, horizontal sand mill, basket sand mill, Rod sand mill, etc. It is mainly composed of a machine body, a grinding cylinder, a disperser, a bottom valve, a motor and a feeding pump. The feeding speed is controlled by the feeding pump. The grinding media of this equipment is generally divided into glass beads, zirconium silicate beads, zirconium oxide beads and so on. Feed pumps generally use gear pumps, diaphragm pumps and other thick slurry feed pumps.

The sand mill is a kind of ultrafine dispersing machine for horizontal wet continuous production. The pre-stirred raw materials are fed into the grinding tank of the main machine, and the grinding tank is filled with a suitable amount of grinding media, such as glass beads, etc., which are rotated at a high speed through the dispersing blade, giving the grinding media sufficient kinetic energy to collide with the dispersed particles to generate shear force. Achieve the effect of dispersion, and then through a special separation device, the dispersed material and the grinding media are separated and discharged. Because it does not require high-level operating skills like three rollers, uniform and excellent quality can be obtained, and large-scale continuous production can be obtained. Therefore, it can improve quality and reduce costs, and it can also be used for the dispersion of high-viscosity substances. It can be applied in paint, ink, medicine, food, cosmetics, pesticide and other industries.
