How a Ball Mill Works

Ball Mills work by using balls to grind materials. Materials such as iron ore, pain and ceramics are added to the ball mill. Next, the ball mill is activated so that it rotates — either on its vertical or horizontal axis. As the ball bill rotates, the balls bounce around while striking the enclosed material. The force of these strikes helps to grind the material into a finer, less-coarse medium.

For a ball mill to work, critical speed must be achieved. Critical speed refers to the speed at which the enclosed balls begin to rotate along the inner walls of the ball mill. If a ball mill fails to reach critical speed, the balls will remain stationary at the bottom where they have little or no impact on the material.

No industry puts its Pumps through the ringer quite like mining. When the price of commodities such as gold spike in the short term, there is no time to lose--companies have to act fast to extract whatever they can as quickly as possible. While this flurry of activity is great for stockholders, it is not ideal for equipment. Many pumps end up falling prey to a myriad of problems that range from corrosion to being crushed by heavier machinery. To protect mine dewatering pumps to the fullest extent, consider these six common threats that pumps may encounter during mining operations.

In the mining industry, Hydrocyclones are mineral processing equipment used in slurry pulps to separate coarse and fine particles according to their size and density. The mixture [slurry pulp] is injected into the hydrocyclone in such a way as to create the vortex and, depending upon the relative densities of the two phases, the centrifugal acceleration will cause the dispersed phase to move away from or towards the central core of the vortex.

Coarse particles exit the bottom of the device (underflow) while fine particles are carried by the central air column and exit at the top (overflow). In metal processing applications, the product stream is the overflow (fine particles) and is typically sent to flotation circuits. The product stream is the underflow (coarse particles), as fines are separated from the final product as a means of quality control.
