bead mill homogenizer

bead mill homogenizer is also called sand mill, the grinding operation is in the fully enclosed and pressure grinding cylinder with high speed operation, so there is no problem of solvent volatilization and air pollution, which can ensure the physical and mental health of operators, and save energy and reduce production cost because there is no solvent volatilization.

The bead mill homogenizer consists of body, main drive, disperser, feeding pump, stepless transmission, cooling system, electrical controller, etc.; the upright integral design integrates the grinding main machine and feeding pump as well as the electrical control box, 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.

What are the uses of the bead mill homogenizer?

The crushing chamber of the bead mill homogenizer consists of a jacket, and the coolant passed inside the jacket can move out the heat generated during cell crushing. The crushing chamber is filled with lead-free glass beads or microbeads of other materials with a diameter of about 1mm. When the motor is started, the glass beads move in various forms with the rotation of the stirring paddle, so that the impact and shearing effect between the beads and the cells is produced, causing the cells to break up and releasing the inclusions. A bead separator is provided at the outlet of the cell homogenate to detain the beads so that the bead separation and crushing can be carried out continuously. The bead mill homogenizer is a cell crusher with high crushing rate and is commonly used in the production of biological drugs.

What are the types of bead mill homogenizer?

High speed bead mill is mainly used for grinding and manufacturing of medium and high viscosity liquid raw materials such as paints, inks, pigments and adhesives. It mainly includes basket type bead mill, horizontal bead mill, three roller bead mill and vertical bead mill.

✔️Basket type bead mill

Coating slurry pre-dispersion and grinding dispersion can be carried out in the movable tank with inclined bottom, without conveying equipment, less auxiliary equipment, easy to clean and color change, especially suitable for small batch and multi-species coating grinding, low speed, smooth running, intermittent production, large basket wear, high manufacturing difficulty, but small loss of paint slurry. It is a relatively advanced paint bead mill.

✔️Horizontal bead mill

The operation procedure is that the pump conveys the liquid raw material into the closed grinding cylinder, and then the host drives the meson grinding beads to run at high speed, so that the paint raw material is mixed, emulsified, dispersed, rubbed, rolled and other submerged functions in the narrow grinding bead gap by the pressurized high-speed rotating impact, and the fineness of the raw material required is reached, and then the grinding is output from the grinding cylinder by the high-speed rotating hard tungsten steel separating gap, which is a cycle grinding The fineness of continuous cycle grinding can reach below 5μm. It is the main recommended equipment in coating bead mill.

✔️Vertical bead mill

Vertical bead mill is easy to operate, large capacity, color change and convenient maintenance; separation device is sieve, overflow discharge, atmospheric pressure operation, can not use finer grinding media, filling volume is also small, only suitable for low viscosity, good flow type paint paste dispersion grinding; slightly high temperature operation, solvent volatilization is serious, sieve easy to crust, grinding fineness is not high; pulp dispersion area is small, stagnant area is large, power consumption is large, dispersion efficiency is low. But this kind of bead mill is used more at present.
