Learn More· After the ball mill is installed, after normal continuous operation for two or three days, check the meshing of the large and small gears. When everything is normal, add the remaining 20% steel balls. The proportion of steel balls in the ball mill is a more complicated technical issue. Each ore dressing plant must carefully analyze its actual
Learn MoreHow to add steel balls to the ball mill in proportion to the size of the steel balls? The present author summarizes the perennial practice and theoretical experience as follows: Usually, a newly installed ball mill has a running-in process. During the running-in process, the amount of steel balls is added for the first time, accounting for 80% of the maximum ball milling capacity. The
Learn MoreBall mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones. The

Learn More· The method of ball distribution for a ball mill can be summarized as follows: 1. Take all the ore samples from a ball mill (usually take new ore and returned sand samples, then match the samples in proportion) for sieving analysis. Divide them into several particle sizes, such as 18-12, 12-10, 10-8, 8-6, etc. Then weigh each particle size, and
Learn MoreInvestigations were carried out in a laboratory ball mill having the size of DxL = 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. Balls were made from steel: S4146, extra high quality, having hardness 62 ± 2 HRC according to Rockwell
Learn MoreWhy is the steel ball amount only added 80% during the ball mill running-in process, because the ball mill is installed, the size and size of the ball mill need to mesh, and the amount (ore amount) is gradually increased. After the ball mill is continuously running for two or three days, the ball mill is stopped. Check the meshing of the large
