Yunnan is known as "non-ferrous metal kingdom." Yunnan has 150 kinds of minerals found in various types, 92 kinds of proven mineral reserves, including 25 kinds of mineral reserves ranked the top three, 54 kinds of mineral reserves rank the top ten, ranking first in the minerals zinc, graphite, tin, cadmium, indium, thallium, and crocidolite. Ball mill industry is the main sales area, to create infinite value for the state, nine categories of mineral resources in Yunnan: black metal minerals, energy minerals, non-ferrous and precious metals mining, chemical non-metallic minerals, rare and rare earth minerals, special non-metallic minerals, metallurgy auxiliary raw minerals, building materials, non-metallic minerals and other minerals and stones. Ball mill drawn is the ideal stone processing of raw materials, contemporary Ball mill industry and the birthplace of the perfect combination of mineral resources.

 Ball mill is a common mineral production in the Ball mill, mill machine to change the original structure, so that the body, chassis integration, installation and on the basis of a one-plane, double row ball main bearings Spherical roller bearings, which reduces energy consumption by 30%, improve fine-grained, processing power increased by 120%. Conical ball mill is material to be broken, and then to smash the key equipment. Ball mill is widely used in cement, silicate product, new building materials, refractory materials, fertilizer, ferrous and non-ferrous mineral and glass ceramics and other production industries of all kinds of ores and other grind-able materials can be dry or wet grinding. Zheng mines produced by the machine rotating ball mill is a horizontal cylindrical device, outer gear, the two positions, lattice-type ball mill. Material from the feed device into the compound into the air shaft screw ball mill evenly the first warehouse, the warehouse there are ladder liner or corrugated liner, built of different size balls, rotating cylinder produces centrifugal force will be brought to a certain ball after the fall height, have severe impact on the material and abrasive. Coarse material in the first position to reach, after single-compartment plate into the second ball mill warehouse, the warehouse lined with flat lining, a steel Ball mill inside, the material further grinding. Powder discharged through the discharge grate plate, the ball mill operation to complete the process.
