High temperature of the ball mill will affact the efficiency 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% -10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded Reasons
A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps are as follows:
Wet milling, a core aspect of the wet grinding process, involves breaking down materials in a liquid medium. The wet ball milling process, a popular choice in many sectors, employs a ball mill to achieve a fine grind. This method is particularly effective for materials that are too hard for standard milling. Steps in Wet Ball Milling Process
