The Status of Hammer Crusher in Cement Production

The hammer crusher is one of the main equipment for intermediate and fine crushing the brittle materials with less than intermediate such as limestone coal and other used in metallurgy, building material, chemical and water - power industry, with a feature of big crushing ratio and even product graininess.Hammer crusher can be divided into: single-section hammer crusher, high-efficiency hammer crusher, sand maker, vertical shaft hammer crusher and reversible hammer crusher. This hammer crusher is applicable for both dry and wet crushing. Hammer crusher is widely used for medium or fine crushing for medium hard and brittle materials by departments of mine, cement, coal, building material, metallurgy, chemical industry, road construction, gas chemical industry and thermal power generation, etc. Coal gangue, coke, slag, limestone, phosphate rock, salt, whiting, gypsum stains, alum, brick and tile, etc. can be crushed by this equipment. The compression strength of the materials shall not exceed 100MPa, while the moisture content shall be lower than 15%.According to statistics, more than 80% raw materials of cement production line are crushed though hammer crusher in primary crushing and impact crusher as secondary crushing equipment, or merely use hammer crusher as crushing equipment. So hammer crusher plays a very important role in cement production line. At present, 2325 double rotors hammer crusher of hongxing company is the first developed and the biggest hammer crusher, which claimed the title of “aircraft carrier of crusher. Limestone raw material of cement factory has the features of heavy production task, labor Intensive and working for 20 hours every day in the normal condition. However, during the whole working process, hammer crusher act as the main machine, once it occurs problems, it should be stop immediately to check and maintain. These problems will cause huge economic lost, the most serious thing is, once the machine occurs problems, the manufacturer do not provide immediately service, the machine owner will lose more.
