Ball mills can operate in either a wet or dry state. While milling without any added liquid is commonplace, adding water or other liquids can produce the finest particles and provide a ready-to-use dispersion at the same time. Grinding media comes in many shapes and types with each having its own specific properties and advantages.
Usually its surface hardness can reach 55-65HRC, volume hardness reaches 50-63HRC, and the average hardness gradient distribution. Its resistance to crushing in large-scale mills is up to 5 times higher than that of ordinary grinding balls, and the number of falling ball impacts is more than 10,000 times.
Keep the hardness just right. When we choose wear-resisting grinding media ball, often be the hardness problem of the grinding media ball.About the hardness, not the bigger the better, is the appropriate hardness value. Simply put, the higher the hardness, the greater the impact reaction during the process of falling, increasing the ball …

Suitable for grinding raw materials with Moh's hardness below 9. Compared with ball mill, higher grinding efficiency, small occupation. Particle size can be adjustable by adjusting parameters such as grinding medium, amplitude, and frequency. The finer powder can be given in …
The rod mill usually uses 50-100mm diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium. The length of steel rod is 25-50mm shorter than the cylinder, and it is usually made of high carbon steel with carbon content of 0.8% – 1%; the loading capacity of rod is about 35% – 45% of the effective volume ...
Ball mill is a major equipment in the production of power plants, cement plants, mines, chemical industry, metallurgy and other industries, the liner is one of the components of the mill, the main role is to protect the cylinder, the cylinder from the grinding body and Material direct impact and friction, help to improve the mill grinding efficiency, increase production and reduce metal ...
The smooth grinding mill liner has a large sliding property, has a strong grinding effect, and is suitable for fine grinding processes. The friction of the unsmoothed grinding mill liner is large, which can improve the material and steel ball very well, and has strong agitation effect, so it is more suitable for rough grinding process.
Grinding mills are specially designed for handling mining operations with high-level hardness. When operating under the mining industry, a grinding mill helps you to produce a perfect size. Grinding mills need less maintenance and downtime while operating. Grinding mills are the one that offers trouble-free operation and helps you to renew the ...
First, ball mill ball has higher hardness and higher HV/E value, in order to resist the grinding of hard abrasive grain. Second, ball mill ball has enough toughness (KI) to resist impact and crack propagation. Third, ball mill steel ball has good anti fatigue ability, in order to resist the effect of alternating stress and impact fatigue wear.
