The crushing and grinding of the ore is a preparation before the sorting. The prerequisite for mineral processing is to achieve the separation of useful minerals in the ore. Since the useful minerals have a small particle size, it is often necessary to grind the ore very finely to achieve a monomer separation. . The ore from the stope is very large. For example, the mining block of the exposed mining can reach a maximum of 1000-1500 mm, so it is necessary to crush the nugget up to 1500 mm to only a few tens of microns (1 micron-10-3). Fine particles of millimeters, the same below, often have to be completed in several stages. In terms of crushing, in large-scale plants, coarse, medium and fine three-stage crushing (also using four-stage) is adopted, so that the size of the ore block is gradually reduced to about 8 to 25 mm, and then sent to a grinding machine for grinding. . Until the useful mineral particles can achieve monomer separation, the grinding is usually one or two stages, sometimes up to three stages.
Introduction: The chemical pumps is a nationally designed energy-saving pump. The performance and technical requirements of the pump are designed according to the performance and size specified in the international standard ISO2858. We mainly produce chemical pumps for metal materials.
Advantages: The advantages of chemical pumps are reasonable layout of the whole series of water conservancy, wide range of users, "back-open" structure, convenient maintenance, efficiency and suction reach the international advanced level
Uses: Widely used in industrial, urban water supply, drainage, can also be used for farmland, orchard drainage, for the transport of clean water or other liquids with physical and chemical properties similar to clean water
According to the different materials of chemical pumps , the application fields are classified as follows:
1) Chemical pumps (stainless steel) are widely used in petroleum, chemical, metallurgy, synthetic fiber, pharmaceutical, food, synthetic fiber and other sectors for the transport of alkaline corrosive media;
2) Chemical pump (cast iron material) is used for industrial, urban water supply and drainage, and can also be used for irrigation and drainage of farmland and orchard for transporting clean water or other liquids with physical and chemical properties similar to clean water.
