Ball Mill. Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills
The first compartment is lined with lifter plates, large grinding media for coarse grinding and special lines ensures optimum lifting of the mill charge. The size distribution of the grinding media in the coarse grinding compartment is designed for the coarsest particles in the mill feed material and to ensure adequate fineness of the material
What particle size range does ball mill grinding produce . Dec 22 2016 What particle size range does ball mill grinding produce There are many types of grinding media suitable for use in a ball mill each material having its own specific properties and
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight
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
Regarding operations, in a ball mill, the grinding media has a higher rate of wear about the rollers and table in the VRM. In ball mills, it is essential to monitor its performance via axial testing to ascertain that the media grading is right and that there are enough top-size media to grind the mill feed materials

The maximum grinding media diameter is determined by the average maximum particle size D95 expressed by the sieve aperture of 95% material passing through. The average grinding media diameter is determined by the average particle size D80 expressed by the sieve aperture of 80% material passing through. The Diameter of Grinding Balls
Sep 05, 2015 Calculate Top Ball Size of Grinding Media -FRED C. BOND Equation & Method. Although it was developed nearly 50 years ago, Bond ‘s method is still useful for calculating necessary mill sizes and power consumption for ball and rod mills. This paper discusses the basic development of the Bond method, the determination of the efficiency
Aug 02, 2013 Based on his work, this formula can be derived for ball diameter sizing and selection: Dm = 6 (log dk) * d^0.5 where D m = the diameter of the single-sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm
Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds
