Grinding cement in ball mills. The principle of the ball mill operation is simple it consists of a rotating drum and grinding media (cylinders, balls etc). The material is placed into the drum which starts rotating. The grinding media and the substance both come in circular motion and at a certain point drop from the walls the bottom of the drum.

In the cement industry, however, this link is weak. The industry’s record of value creation is spotty, with ROIC levels roughly equal to the cost of capital, at around 9 percent. Behind the lackluster ROIC, two drivers stand out high goodwill (seen in the low tangible capital ratio) and inadequate capital efficiency. Call it bad timing.
Independent of the chrome content of the grinding balls, the specific wear rate of the grinding media var ies approximately from 15 110 grams per ton of cement. This depends on the different tempering pro cess of the grinding media.
One ton of cement. During this stage, the clinker particles are substantially reduced in size to generate a certain level of fineness as it has a direct influence on such performance characteristics of the final product as rate of hydration, water demand, strength development, and other. The grinding objectives tying together the energy and.
The hardness is stable and fluctuated little, and the wear resistance is very good. The impact energy is 4.7 5j CM2, the impact toughness is very good, the breakage rate of the grinding ball is less than 1 3. The ore consumption is 0.23 kg ton compared with 0.6 kg ton of forging ball.
