the ball mill is powered by a fairly robust DC motor salvaged from a junked printer. It had a pulley for a fine-toothed belt on it. It was left in place and it seems to drive the heavy round rubber belt well without slipping. the motor was mounted using screws on only one side, which were deliberately left loose. this allows the motor to dec 08, 2009 re: how to estimate the wear rate for ball mill. ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. with new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated.planetary ball mills vibration mills mixer mill MM 400 feed material: hard, medium-hard, soft, brittle, elastic, fibrous material feed size: mm final fineness: setting of vibrational frequency: digital, Hz
the ball mill is a tumbling mill that uses steel balls as the grinding media. the length of the cylindrical shell is usually 11.5 times the shell diameter .the feed can be dry, with less than moisture to minimize ball coating, or slurry containing 2040% water by weight.slice mill of diameter by wide would replicate the result of a normal production, mill in diameter as 120 long. slice mill is the same diameter as the production mill but shorter in length. click to request a ball mill quote online or call 012 to speak with an expert at paul abbe to help you determine retsch is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application. the high energy ball mill max and MM 500 were developed for grinding with the highest energy input. the innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time with only minor warming
