Overflow Ball Mill are generally used to grind materials with 14 inch and finer to the particle size of 20 to 75 microns. In order to achieve reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reground.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AGSAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
stirred media mills and high-pressure grinding rolls, ball mills still retain a significant part of their importance in grinding, being widely used from minerals and cement, to chemicals and ceramics.

Analysis and comparison, the test results are shown in Figure . Fig 3 Comparison of overflow fineness under different filling ratios using alumina balls and steel ball as grinding mediums
For overflow ball mills, the charge should not exceed 45 of the mill volume . For grate discharge mills, the charge should occupy about 50 of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
Sep 01, 2016 The effect on overflow ball mill power draw of the minor changes attributable to the increased feed rate may be different to that on an AGSAG mill. For an overflow ball mill, the increased slurry pool volume resulting from the increased mill feed rate will not lead to an increase in ball mill power draw rather more often the opposite.
Jul 01, 2017 The model includes the last 1.5 m axial length of the end section of a 6 m diameter overflow ball mill with a trommel screen attached for collecting the mill discharge as shown in Fig. 3. This geometry was built from details estimated from a range of manufacturer website sources and is not intended to correspond to any specific milltrommel ...
Nov 07, 2018 1. Overflow Pipe Diameter. The diameter of the overflow pipe has a great influence overall hydrocyclone. The larger the diameter of the overflow pipe is, the lower the pressure will be, the overflow productivity will increase, the overflow fineness will become coarser, and the classification efficiency will first stabilize and then decrease.
The helical blades on the overflow side are all under the overflow surface. The classifier is suitable for classifying ore materials with a flow particle size between 0.15 to 0.07mm. The sand return side adds an automatic lifting device for returning sand and cancels the ball mill
