the 911mpeppgr426 is a small 300 kilo to 3.5 ton per 24 hour day capacity grinding mill acting primarily as a rod mill but can effortlessly be converted to a ball mill. thanks to the integrated spiral classifier, it forms an easy to operate closed-circuit grinding plant. it includes a fine ore hopper, vibrating feeder and starter rod load.
alibaba.com offers 552 zinc ore ball mill products. about 75% of these are mine mill, 2% are other fabrication services, and 1% are ceramics. a wide variety of zinc ore ball mill options are available to you, such as ac motor, dc motor, and stepper motor.
a mechanical classifier often receives its feed from a ball mill and produces (1) finished material which overflows to the next operation and (2) sand which returns to the mill for further size-reduction. where t = tons of ore per hour. and q = tons of added water per hour or t = tons of ore (for batch determinations) and q = tons of added
