1. Introduction. Grinding operation is used extensively in the industry of beneficiation, metallurgy, chemical engineering, and electric power. Assisted by the impact and abrasion between media (steel ball, steel rod, gravel, ceramic ball) and ore, the grinding operation reduces the particle size in the mill [[1], [2], [3]].To produce the …

Steel bars are round steel rods cut into sizes. The steel bars used in ball mills are usually with diameters between 40mm and 90mm. The length of steel bars should be 50-100 mm shorter than that of the mill chamber. Grinding Media Material. The grinding media in the ball mill is required to have great wear resistance and impact resistance.

The choice of milling media is not arbitrary. The size of the grinding balls influences the final particle size; smaller balls are better for achieving a finer product. Similarly, the material of the balls affects their impact strength and durability, with metal balls being preferable for harder and denser materials while plastic balls may be the …

The working principle of a ball mill is based on the impact and attrition between the balls and the grinding media. As the mill rotates, the grinding media (usually steel or ceramic balls) are lifted to a certain height and then allowed to fall freely, causing the materials to be reduced in size by the impact and abrasive forces generated ...
