Iron Ore Mining Equipment
Iron ore grinding process, most of the grinding process, two pieces of small and medium-sized concentrator with a iron ore mining equipment. As a result of new technology of grinding fine screen again, in recent years some concentrator has two grinding into three sections by grinding. Iron ore mining equipment is generally small, the largest 3.6 m * 6 m, ball mill most stick mill 3.2 m * 4.5 m, the largest since the mill 5.5 m * 1.8 m, pebble mill 2.7 m by 3.6 m. After grinding classification is basically the use of spiral classifier. In order to improve the efficiency, part of the concentrator of hydrocyclone to replace spiral classifier.
Due to the strong magnetic ore, grinding good choose, domestic magnetic separation plant adopts stage grinding and stage grinding process, as the coarse grained disseminated magnetite using a iron ore mining equipment, microgranular disseminated magnetite with two or three period of grinding.
Concentrator generally use coarse broken, broken and fine broken in three sections of broken ore crushing process. Coarse broken multi-purpose 1.2 m or 1.5 m iron ore mining equipment, broken in the use of 2.1 m or 2.1 m standard cone crusher, fine broken by 2.1 m or 2.2 m short head cone crusher. Through the thick broken ore, its fragmentation is not greater than 1 m, and then after, fine crushing and screening ore particle size is less than 12 mm grinding groove of the final product.
