Bead mill supplier factory manufacturer

The bead mill consists of body, main drive, disperser, feeding pump, stepless transmission, cooling system, electrical controller, etc.; the upright integral design integrates the grinding host and feeding pump as well as the electrical control box into one, so that the vertical sand mill does not occupy space and is easy to operate; the grinding cylinder is of cooling jacket type design, so that the cooling water can enter and exit one after another to cool the temperature generated in the grinding operation of the sand mill.

How does the bead mill work?

The grinding operation of the bead mill is that the feeding pump sends the pre-dispersed and wetted slurry from the bottom of the grinding cylinder upward into the grinding cylinder, and the grinding beads with heavy specific gravity will fall downward, so that the raw material will produce upward and downward convection in the grinding cylinder with pressure, and the raw material will be emulsified, dispersed, rubbed and ground in the gap of the grinding beads by pressure and high-speed rotating interlocking impact, so that the required fineness can be reached quickly, and then the grinding will be separated by the hard tungsten steel with high-speed rotation. After grinding, the hard tungsten steel separating the gap by high speed rotation is output outside the grinding cylinder, which is a cycle grinding operation, and the fineness of continuous cycle grinding can reach below 5μm.

The difference between sand mill, bead mill and grinding machine

✔️What is sand mill?

Sand mill is also called bead mill, which is mainly used for wet grinding of chemical liquid products and can be broadly divided into vertical sand mill, basket sand mill, horizontal sand mill, rod sand mill and so on according to the use performance. At present, the grinding effect of the sand mill of some manufacturers has been able to reach the nano level. Sand mill is mainly composed of body, grinding cylinder, disperser, bottom valve, motor and feeding pump, and the speed of feeding is controlled by feeding pump. The grinding medium of this equipment is generally divided into glass beads, zirconium silicate beads, zirconium oxide beads, etc. The feeding pump generally adopts gear pump, diaphragm pump and other thick slurry feeding pumps.

✔️What is a grinding machine?

The lapping machine is controlled by stepless speed control system, which can easily adjust the grinding speed suitable for grinding various parts. It adopts closed-loop feedback of electric-pneumatic proportional valve to control the pressure of the grinder, which can regulate the pressure device independently. The upper plate is set with a slow fall function to effectively prevent the breaking of thin and brittle workpieces. Through a time relay and a grinding counter, the grinding time and the number of grinding turns can be accurately set and controlled according to the processing requirements. When working, the pressure mode can be adjusted, and the alarm will stop automatically when the grinding set time or lap speed is reached, realizing semi-automatic operation.

Grinding mill variable speed control method, grinding processing has three stages, namely, the beginning stage, the formal stage and the end stage. In the beginning stage, the grinding tool rotates at an increasing speed, the grinding tool rotates at a constant speed in the formal stage, and the grinding tool rotates at a reduced speed in the end stage. reaches the official grinding speed, the acceleration of the grinding tool speed drops to zero.
