Within these limits a rod mill is usually superior to and more efficient than a ball mill. The basic principle for rod grinding is reduction by line contact between rods extending the full length of the mill, resulting in selective grinding carried out on the largest particle sizes. This results in a minimum production of extreme fines or

Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency. Autogenous mill

Mill Speed Critical Speed. Mill Speed . No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product.

Comparative batch tests on ball mill feed with the current and an alternative ball charge may show increased grinding rate through the size of interest, but lower rates at coarser particle sizes. Locked cycle tests are then needed to determine whether a net increase in grinding efficiency will result.

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non ferrous metals. The ball mill can grind various ores and other materials either wet or dry.
