In the grinding operation, the consumption of steel ball is very large, which is about 10 times more than the loss of ball mill liner. in order to make up for the loss of steel ball and keep the size of the steel ball unchanged in the ball mill machine, it is necessary to add the steel ball regularly according to a.
Influence of ball mill structure on grinding efficiency. the grinding efficiency of a ball mill is affected by many factors, but one thing you may not know is that the structure of the ball mill also affects the grinding efficiency.this paper will discusses this problem from four aspects: barrel length, diameter, ball mill speed and lining plate.. the function of the ball mill is subordinate.
Jan 17, 2011 the best way to enhance their working efficiency is to research and develop.i just said there are many problems in using ball mill which just show its degree of concern. as a matter of fact, some problems occured because of incorrect operation and bad maintenance work. if people make ball mill in a good state,the problem isn't problem any.
Mar 01, 1992 the overall effect of a mixture of balls in the mill may be taken as the linear weighted sum (austin et al., 1984e): l s, = z mtsjj ( 14 ) /=1 l l bi,= ( m,sj.,bo,l) / z rnlsj.r (15) l=1 r=l the ball charge in the mill is split into l ball classes with diameters in a 4x/2 ratio, and mt is the relative mass frequency function of balls of size.

The effects of percent solids, mill loading, and grinding time on product size distribution and ball wear were studied in a laboratory ball mill for a taconite ore. mild steel balls and hcla steel balls were used to examine the role that ball hardness play in grinding. net production of −44- m (−325-mesh) material reached maximum at 70% solids, whereas the ball wear decreased as pulp.
The failure of the ball mill in the grinding process will affect the output and efficiency. so，what abnormal signs will occur before the machine going to malfunction? here we list 17 signs to mention to you that maybe you should give your machine.

The multi-segment ball mill model developed by whiten and kavetsky has been used together with an extensive range of data from operating mills to establish the parameters of a new ball mill model.
The product from the sag mill is further reduced in size using pebble crushers and ball mills. hence, typical gold or copper ore requires between 2.0 and 7.5 kwh per ton of energy to reduce the particle size. considering a typical mining operation processes 10,000 to 100,000 tons per day the energy expenditure in grinding is 50 percent of the.
The productivity of the overflow ball mill lower about 10 to 15 percent of the grid ball mill of same type . but over-crushing problem is serious to the overflow machine, while the granularity is small.
The reasons of over high material level in ball mill are three factors. the first is the water-material ratio reduces, which reduces the carrying capacity of water, leads to the rise of material level. the second is the over larged feeding material size. it increase the residence time in ball mill of.
