With the rise of the revitalization of Africa and other developing countries in the recent years, the national infrastructure is gradually being mentioned in the national development agenda. Therefore, milling machines, crusher, cement and sand and gravel production engineering machinery accounted for a large part of China's total export volume. At the beginning of 2013, Liming Heavy Industry get a good news, the ultrafine mill exported to Egypt again.

　　The ultra-fine mill is a fine powder and ultrafine powder grinding processing equipment, it is mainly applied in Mid-low hardness, Mohs hardness <6 non-flammable and explosive brittle material. Silicon carbide micro-grinding is widely used in calcite, diatomite, barite, gypsum, alunite, graphite, fluorite, phosphate rock, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, illite , pyrophyllite, vermiculite, potassium ore, pumice, etc.

　　

Pressure micro-grinding is a superfine mill, the milling equipment , is also referred to as the high-pressure grinding, which can be used in the processing of more than 280 kinds of high fine powder ,such as, barite, limestone, ceramics, slag, etc, whose Mohs hardness of not greater than 9.3 and humidity below 6% of non-flammable and explosive in mining, metallurgy, chemical industry, building materials and other industries, and the product size can range from 80 to 425 mesh (the smallest 1,000 head).

 

　　In general, pressure micro-grinding is mainly composed of the host, blowers, ultra-fine analysis machine, finished the cyclone accumulated powder, bag filter and connecting duct piping and other components. According to the customer, it can also be equipped with hoist, storage silos, control cabinet, crusher and other auxiliary equipment.

　　The performance characteristics of Pressure micro-grinding:

　　1, the scope range large, a variety of materials all can be grinded for hardness no mre than 6.

　　2, compared with other similar mill, the grinding pressure of roller to the material can increase 800-1200Kg, under the action of the high-pressure spring.

　　3, energy saving. In the case of the same yield and fineness, and the energy consumption of the system is only one-third of the jet mill.

　　4, a small investment, high income. In the case of the same yield and fineness, high-pressure micro-grinding's prices is only one-eighth of the jet mill.

　　5, Fewer production processes ,the material below 25mm can be processed directly into the machine.

　　6, feed size large, and the disposable average particle size of the material can reach 6.5um super fine powder.

　　7, The effect of the dust of the high-pressure micro-grinding fully meet national standards for dust emissions.
