The difference between sand mill, bead mill and grinder

2021-11-29

Sand mills are also called bead mills, which are mainly used for wet grinding of chemical liquid products. According to their performance, they can be roughly divided into vertical sand mills, horizontal sand mills, and rod sand mills. At present, the grinding effect of sand mills from some manufacturers has reached the nanometer level. The Sand Mill is mainly composed of a 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 medium 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 grinding machine is controlled by a stepless speed regulation system, which can easily adjust the grinding speed suitable for grinding various parts. Adopt electric-pneumatic proportional valve closed-loop feedback to control the pressure of the grinder, and the pressure device can be independently regulated. The upper plate is equipped with a slow-down function, which effectively prevents the thin and brittle workpieces from being broken. Through a time relay and a grinding counter, the grinding time and the number of grinding cycles can be accurately set and controlled according to the processing requirements. The pressure mode can be adjusted during work, and when the grinding time or lap speed is reached, it will automatically stop and give an alarm, realizing semi-automatic operation.
