Product Description

Chengda can provide diameter 4.6mm-140mm and the chrome content ranges from 0.8%-28%,which can be customized according to different needs of users.
It not only improves the grinding efficiency,reduces the time of stopping the grinding machine for selection and adding of the balls,but also extends the clearance cycle,reducesthe labor intensity,and has important significance for improving the output of themill,ensuringthe quality of the abrasive,and reducing the consumption of power consumption and the grinding media.

Optimal Hardness ranging from 57 - 66 HRc , are essentially used in the first chamber of the mills for crushing the feed material. These balls impart potential energy for crushing and thus required to possess a combination of wear and impact resistance
Grinding by attrition is accomplished by numerous small balls of varying sizes from 15mm to 60mm,Chrome range from 10% - 30% and Optimum Hardness ranging from 60 - 69HRc in second chamber. These balls contribute significantly to the grinding efficiency of the mills. 

High wear resistance: Mine special high chromium grinding ball contains a high proportion of chromium element, chromium content is usually between 10% and 21%, which makes the grinding ball surface hardness, excellent wear resistance, suitable for use in severe wear mining environment.

High hardness: After heat treatment processes (such as quenching and tempering), high chromium grinding balls can obtain a high Rockwell hardness (HRC), usually above HRC58, which helps to improve the impact resistance and wear resistance of the grinding ball.

Good impact toughness: While maintaining high hardness, high chromium mill balls also have good toughness, which makes them less likely to break when subjected to shocks and collisions in the mine mill.

Long service life: Due to high wear resistance and high hardness, the service life of high-chromium grinding balls for mining is longer than that of ordinary grinding balls, reducing the frequency of replacement and reducing long-term operating costs.

High chromium content: The increase of chromium content helps to form more chromium carbide hard phase, which increases the ability of the mill ball to resist wear.

Economic benefits: Although the initial cost of high-chromium grinding balls for mine use may be higher than that of low-chromium or medium-chromium grinding balls, they can bring better economic benefits to mining enterprises in the long run due to their longer service life and lower wear rate.

Environmental adaptability: The high chromium mill is suitable for a variety of mine environments, including wet and dry grinding, as well as handling ores of different hardness and properties.

Production technology: Some special high-chromium grinding balls for mines use special production processes, such as secondary metamorphism treatment, to further improve the performance of the grinding ball.

Widely used: In addition to the mining industry, high chromium grinding ball is also widely used in cement, thermal power generation, flue gas desulfurization, chemical industry, coal water slurry, pellets, slag, ultrafine powder, fly ash, calcium carbonate, quartz sand and other industries.
