Wet grinding: Wet milling was carried out in a similar matter as dry grinding was done at three different mill speed which 45, 70 and 90% of the critical speed of ball mill. The slurry was made using one kg ore and four liters of water. Once the sample was taken out, the wet screening test was performed.

The water can wash away the fine particles in time to avoid overgrinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.

① Ceramic Ball Mill: It prevents iron pollution and is especially suitable for grinding glass and ceramics. Ceramic mill balls are white aluminum balls with a diameter within mm. ② Rod Mill: Same as ball mills, except for the use of steel rods as grinding media. The maximum feed size is 50 mm. The output size is 435 mesh.

This is particularly true for some of the secondary grinding (primary ball mills) of magnetic iron ores. In magnetic iron ore grinding, the silica levels are continually being decreased from crushing to rod milling to ball milling by intermediate concentration steps. Subsequently, the wear environment becomes progressively less abrasive.

Ball mills are progressively used to grind the ores for particle size reduction and to liberate valuable minerals from the ores. The grinding of ore is a highly energyintensive process [1,2,3,4].In this process, the size of the particle obtained depends on the energy consumption of the ball mill.

Each mill measures about 12m in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart. From the AG mills, the ore travels to the primary magnetic separators where the iron is drawn away from the waste material before it's screened and fed into the ball mills.

Reason: This is a common problem mining ball mills face, resulting in low productivity and low ore processing efficiency. One reason may be the improper design of the grinding chamber, which affects the flow of materials and reduces grinding efficiency. Additionally, worn or damaged liners can hinder the grinding process by reducing the effective impact between the ball and the material.
