The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–15 times the shell diameter (Figure 811)The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight
1 Over the past 15 years, mine-to-mill studies have focused attention on the impact blast fragmentation has on concentrator throughput Blasting provides the first opportunity for comminution – or size reduction It is also a cheaper and more efficient process, compared to both crushing and grinding
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cementMost cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills
The theoretical critical speed of a ball mill is the speed at which the centrifugal force is sufficiently large to cause a small particle to adhere to the shell interior for a full revolution of the mill
