Get Pricethe batch ball mill is a kind of ball milling machine which discharges the material in one time according to the nature of the material. different from continuous ball mill, batch type ball mill grinds powder by times and adopts intermittent operation. the batch mill is mainly used for the mixing and grinding of materials, with uniform product fineness and saving power.
download citation optimization of continuous ball mills used for finish-grinding of cement by varying the l/d ratio, ball charge filling ratio, ball size and residence time during the last
according to different operation process, ball grinding mill can be divided into continuous ball mill and batch ball mill. the feeding and discharging process of the continuous type ball mill is continuous, which can be produced in open or closed circuit grinding applications, such as cement ball mill, ceramic ball mill.
conical ball mills used wet or dry, closed or open circuit, conical ball mills provide a classifying action within the body of the mill due to particles of greater size tending to reside at a point of greater diameter. this characteristic delivers increased efficiency and lower power consumption. conical mills may also be air-swept when run dry.
apr 01, 2013 the reference point is a conventional ball mill circuit in closed circuit with cyclones operating at 250 circulating load and having 38 of fine material reporting to cyclone underflow, resulting in a classification efficiency of 50. this efficiency was chosen as an industrial practice average from the data presented in fig. 6.

it can be observed that for a ball mill circuit closed with cyclones, circuit relative capacity is not expected to increase significantly by increasing circulating load from 250 to 600. this is because of the reduction in classification efficiency from 50 to 30 as calculated by eq. (11). compared to the reference point, a ball mill
