Ceramic grinding ball on the material requirements are mainly reflected in the following aspects, to ensure the smooth grinding process and grinding effect of high efficiency:
1. Material hardness:
- Ceramic grinding ball has high hardness and wear resistance, so it is suitable for grinding materials with low hardness.
- When grinding materials with too high hardness, it may cause abrasion to the ceramic grinding ball, affecting its service life and grinding effect.
2. material particle size:
– The maximum particle size of the material to be ground should be ≤1mm for open-circuit grinding and ≤2mm for closed-circuit grinding.
– The average particle size of grinding material also has specific requirements, such as open mill ≤ R0.08 @ 35%, closed mill ≤ R0.08 @ 45%.
– These particle size requirements are to ensure the grinding efficiency and ceramic grinding ball wear control.
3. Material moisture:
– The average moisture of the material to be ground should be ≤1.5%. Excessive humidity may cause the material to adhere to the grinding balls, affecting the grinding effect and equipment operation.
4. material properties:
– Ceramic grinding balls are suitable for different materials, such as high alumina ceramic balls are suitable for grinding aluminum ore, siliceous ore and other ores and other materials with fine particle requirements; zirconia grinding balls are suitable for grinding materials with high hardness; silicon carbide grinding balls are suitable for grinding high temperature materials.
– The chemical stability of the material and the chemical reaction with the grinding balls are also factors to be considered to avoid contamination or damage to the grinding balls during the grinding process.
5. Material purity:
– Ceramic grinding balls excel in grinding materials requiring high purity due to their high purity characteristics, which do not contaminate the material during the grinding process.
6. Material shape and fluidity:
– The shape and fluidity of the material will affect its distribution and grinding effect in the grinding process. Proper material shape and fluidity are conducive to uniform grinding and efficient energy transfer.
Ceramic grinding ball on the material requirements mainly include material hardness, particle size, humidity, nature, purity and shape fluidity and so on. When selecting ceramic grinding balls, it is necessary to evaluate and select according to the specific material characteristics and grinding requirements to ensure the smooth running of the grinding process and the high efficiency of the grinding effect.
