Bead mill machines are material processing equipment designed to grind or disperse the solid particles into micron and nano scales, usually in wet grinding.
It covers laboratory bead mill, vertical bead mill, centrifugal bead mill, and bead mills in type pin, turbo, disc, basket, etc., with grinding fineness reaching 20nm at the finest.
Dry grinding refers to the moisture content of the material not exceeding 4% during grinding. Wet grinding refers to grinding raw materials that are suspended in the carrier liquid stream, with the appropriate additives like dispersion addition to help grinding.
The moisture content of the material in wet grinding exceeding 50% can overcome the problem of dust flying.
Horizontal bead mill refers to the motor and grinding chamber on the same level, the material is ground along the horizontal axis through the rotor driven by the motor.
Vertical bead mill, on the other hand, means that the motor and grinding chamber are in the vertical direction, and the material is through the dispersing disk driven by the motor to achieve the grinding.
Horizontal bead mills are more stable, efficient, and safer, with grinding material easier to disperse and flow.
There are many kinds of rotor structures of bead mill, mainly basket type, disk type, turbine type, pin type bead mill, and so on.
Bead mills can grind raw materials to the desired particle size with great precision. In many industries, the purity and quality of the material have a critical impact on performance. This is especially important for products that require precise dosing, such as pharmaceuticals, MLCC, new energy sources, and lithium batteries.
1. Define the purpose of the bead mill, for experiments or large-scale mass production;
2. Choose the equipment model according to the particle size of the grinding material;
3. Choose the structure and material of the bead mill according to the material properties.
Dry grinding, without medium liquid, is suitable for materials that are easily contaminated by liquids, but the material loss is large.
Wet grinding, with medium liquid added, can reduce material loss and control particle shape, and the grinding efficiency is generally higher than dry grinding.
The bead mill price is determined by the structure, the material of the grinding chamber and rotor, the specifications, etc., also varying from the different production processes and configurations.
Clean and maintain the machine regularly to prevent accumulated dust and impurities from affecting working efficiency.
The most important thing is to operate following the instruction manual to keep the bead mill machine in good condition.
