If the ore is hard, comminution is not only the largest energy consumer in mineral processing. It's also the largest capital expense and operating cost. In modern lowgrade mining operations, comminution uses energy and other consumables on a scale that is unprecedented. Today, new deposits are being found in more remote areas and are trending ...

The simplest grinding circuit consists of a ball or rod mill in closed circuit with a classifier; the flow sheet is shown in Fig. 25 and the actual layout in Fig. 9. This singlestage circuit is chiefly employed for coarse grinding when a product finer than 65 mesh is not required, but it can be adapted for fine grinding by substituting a bowl ...

And each series contains a number of models. In general, the bigger the size of the ball mill, the more expensive the price. Generally, the price of a small ball mill is about 10,000 to 40,000 dollars, the price of a medium ball mill is between 40,000 to 200,000 dollars, and the price of a large ball mill is millions of dollars.
The cost of optimization is minimal since inspecting the mill and the resulting modifications such as regrading the grinding media or moving the diaphragm are labor elements that can be handled by the plant's maintenance crew. Upgrading the classifier and baghouse involves capital expenditure with a high benefit to cost ratio.
CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
Bauxite—the raw material used by primary smelters—is largely sourced overseas. Bauxite reserves are heavily concentrated in Australia, Guinea, and Vietnam. In 2021, the United States imported million metric tons of bauxite; about 70% was refined into alumina used by primary

The Ball Mill. Ball mills or tubular mills are built with diameters up to meters and lengths up to 20 meters; the drive ratings today are as high as 10,000 kW with stable operation, and maintenance of a ball mill is relatively simple . The maintenance cost and the capital cost are relatively low compared to other technologies.
