Development situation of gold ore beneficiation equipment

Crushing energy consumption of grinding process occupies a large proportion in the whole processing process, therefore, the crushing and grinding equipment plays an important role in the processing, has a great impact on the energy consumption of the whole processing, is directly related to the level of the cost of mineral products. In order to reduce energy consumption, increase production capacity, early in 1980 proposed the "more crushing and less grinding" policy, over the past 20 years, China has done a lot of work in this area, has made remarkable achievements. So far, the main use of metal ore dressing production of jaw crusher and cone crusher, in view of this situation, both at home and abroad on these two kinds of equipment has been improved and developed more. The PE series jaw crusher has the advantages of simple structure, reliable operation, low operating costs; the crushing cavity depth and no dead zone, improve the feeding ability and yield; big crushing ratio, uniform product size; gasket type discharge opening adjusting device is convenient, reliable, large adjusting range, increase the flexibility of the device, which can meet the the requirements of different users; lubrication system is safe and reliable, convenient replacement parts, maintenance workload is small; the single equipment energy saving of 15% to 30%, more than double the system energy saving and low noise, less dust. Mainly used for all kinds of ores and medium - size bulk materials broken, broken compressive strength is not more than 320Mpa material, divided into coarse and fine broken two broken. Widely used in mining, metallurgy, building materials, highway, railway, water conservancy and chemical industries etc.

The most commonly used concentrator grinding device for horizontal cylindrical grinder mill, according to the characteristics of the medium can be divided into: rod mill, ball mill, mill, mill (dry and wet) or semi autogenous mill. The ball mill has the advantages of simple structure, specifications can be small or large, large crushing ratio (30`100), can be wet grinding and dry grinding, can be used to deal with all kinds of mineral raw materials and different scale of production enterprises; ball mill production stable, easy to realize automatic control. On the adaptability and applicability, the current can not be compared with any mill. The characteristics of the rod mill is the rod to rod movement with selective crushing effect, the more uniform particle crushing phenomenon, lighter, so the treatment of brittleness, density material with appropriate. Can be used as ball mill feed pre crushing, used in the treatment of open circuit crushing products, constitute the so-called broken rod mill. Ball milling process. Many domestic research institutes and universities to do much work on the development of flotation machine flotation machine, the successful development of various types of equipment, over the years in the mineral processing industry has played an important role. At present, still adopts the traditional concentrated equipment model, high efficiency thickener get promotion in a certain range. In recent years, a major breakthrough in the filtration equipment. In the mineral processing industry is mainly for the development and application of disc filter, filter and ceramic filter.
