subject: The Mining Machinery Supplied By Hongxing [print this page] Hongxing machinery is able to supply the largest range of ore mining machinery for the customers.There are many kinds of minerals. Based on the nature of mineral and industry uses, ores are classified into metal ore, nonmetalliferous ore and flammable machine rock. According to the types of metal containing, ores can be divided into the single metal ore, multi-metal composite ore. Ore mining usually through the following steps: crushing and screening, grinding and classification, material separation, concentrates and residue processing, dressing conduction, etc.
Crushing and screening equipment
At present, the medium and small ore mining factories adopt second paragraph or three-stage crushing process; Large scale ore mining enterprises adopt three-stage crushing process; As the block of undressed ore is too big, some large factories also use four sections of broken open process. The typical crushing and screening equipments in ore mining plant are jaw crusher, impact crusher, cone crusher, and sand maker.
Grinding and classification
In the ore mining factory, grinding operation is falling behind the crushing processing. However, this operation continues crushing processing to ore is an important part of the ore separation. The quality of the grinding product has direct impact on the level of the choosing index. The combination of grinding machine and classifier grinding process is called a ore-milling classification process. The grinding process should make its final product size up the following operation needs. Besides, the grinding process should be simple, flexible and has certain adaptability. The main grinding process equipments are ball mill, grate ball mill, wet grinding machine, Raymond mill, autogenous mill, semi-autogenous mill, vibrating screen and spiral classifier, etc.
Material separating
Material separating mainly includes three patterns: heavy election, magnetic separation, the flotation, electric separation, pick processing, the chemical separation and microbe mineral processing. According to physical and chemical property of the mineral stone, we choose different ways. The main production equipments are magnetic separator, flotation separator, screw chute, concentrator table, high strength magnetized magnetic separator, etc.
The modern enterprise's scientific management method our principle to keep abreast of the societys development.
