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 11.5 times the shell diameter (Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.

If the hardness of the ore increases, the particle size in the mill discharge from ball mill 1 will increase. With the same water addition to sump 1 the particle size of Cyclone 1 overflow will increase. This will decrease the ratio, and hence the control loop will add more water to keep the ratio constant. However, the amount of slurry ...

of the Bond ball mill grindability test. For all model based methods, a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw. Morrell (1996) proposed a mathematical model for autogenous, semi-autogenous and ball mills which is based on the motion of grinding charge inside the mill.
If the cyclone keeps returning ore to the ball mill, the total volume of ore will be increasing in the grinding circuit, as is the density of the slurry. The recirculating ore is also called circulating load. If the grinding process becomes less efficient, the circuit load will climb until its volume is greater
Crushing is followed by grinding and it is quite common to use nowadays two grinding stages in a semi-autogenous ball mill circuit (SABC). The size reduction ratio in grinding gets lower the finer the material gets and from 1 mm to 100 microns often two grinding stages are required.

Aug 30, 2019 1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of ...
