How to choose the bead mill - grinding barrel material?

There are several key factors to consider:

1. Characteristics of grinding materials:

Hardness: When grinding high-hardness materials, it is necessary to choose a grinding barrel material with good wear resistance, such as tungsten carbide, zirconia, etc.

Corrosion: When grinding corrosive materials, it is necessary to choose a corrosion-resistant grinding barrel material, such as stainless steel, ceramic, polyurethane, etc.

Viscosity: When grinding high-viscosity materials, it is necessary to choose the grinding barrel material with smooth inner wall and not easy to stick.

Temperature: If the temperature rises during the grinding process, it is necessary to choose a high-temperature grinding barrel material.

Need to avoid metal ion contamination: If the grinding material is sensitive to metal ions, it is necessary to choose a non-metallic grinding barrel, such as ceramic, polyurethane, etc.

2. Grinding fineness requirements:

Materials with high grinding fineness requirements need to choose a grinding barrel with smoother inner wall and higher grinding efficiency.

3. Material of grinding barrel:

Stainless steel: good versatility, corrosion resistance, easy to clean, but relatively poor wear resistance.

Ceramics: good wear resistance, corrosion resistance, not easy to produce metal ion pollution, but the price is higher.

Tungsten carbide: Extremely high wear resistance, suitable for grinding high-hardness materials, but expensive.

Zirconia: between ceramic and tungsten carbide, wear resistance and moderate price.

Polyurethane: good wear resistance, corrosion resistance, certain elasticity, suitable for grinding impact-sensitive materials.

Nylon: low price, general wear resistance, suitable for grinding low hardness materials.

Size of grinding drum:

Select the appropriate grinding drum size according to the amount of material per grinding. Too small grinding bucket may lead to low grinding efficiency, and too large grinding bucket may lead to material waste.

4. The structure of the grinding barrel:

Grinding drum with jacket: The temperature during grinding can be controlled by cooling or heating the jacket.

Cone grinding barrel: is conducive to the flow and mixing of materials, improve the grinding efficiency.

In SUMMARY:

When selecting the grinding barrel of the sand mill, it is necessary to comprehensively consider the characteristics of the grinding material, the requirements of the grinding fineness, the material, size and structure of the grinding barrel.
