bentonite mining equipment when staff survey conducted in Nanjing City area mineral exploration, discovery of a bentonite mine source band, the sampling and analysis to determine the high content of montmorillonite bentonite, which is the first six high-grade and Masami recently discovered Mongolia nontronite deposit, the deposit is located in Nanjing County five of the region, an area of approximately 10.85 square kilometers, layered distribution, the color is pink, mostly white, waxy luster, with an average thickness of mining area of approximately 2.6 to 6.8 meters. The discovery of montmorillonite ore reserves of 8.8 million metric tons, the deposit is shallow, easily mined, high grade, high purity. Currently, the deposit has been approved by the relevant departments of land and resources, will be formally transferred from the pre-production stage reconnaissance phase. coal processing machinery : Coal is Vietnam's most important energy resources, has proven reserves of about 22 billion tons, and the variety, good quality, Hongji quality anthracite coal as the representative of the world-famous. Vietnamese government is focusing on the development of the coal industry in order to promote economic development and improve people's lives. In Vietnam, coal is the main fuel for thermal power plants not only, but also building materials, important fuel chemical, transportation, food processing and other industries. In addition, coal or fuel Vietnamese families and rural people. As an export commodity, coal can earn foreign exchange. Vietnam Coal has been exported to the world 30 countries and regions, including China, Japan, Korea, Thailand, Malaysia, India and the European Union. Vietnam coal mining and processing industry, the lack of deep-processing technology, small-scale enterprises, many products to concentrate even raw ore exports, resulting in waste and loss of resources, many coal mines and coal preparation plant is not high degree of mechanization need to rebuild or modernize equipment upgrades to increase the body mining production capacity to meet the targets. Vietnam's main coal mining machinery currently rely on foreign imports, including Chinese products more in line with Vietnam's national conditions, occupy a considerable share of Vietnam's coal industry has been widely loved and trusted, Chinese mining machinery and equipment, security technology equipment, powder processing equipment, clean coal processing equipment and other products exported to Vietnam prospect. coal crusher machine : China's production of crusher, according to the application can be roughly divided into ordinary (PF-type) and coal use (PFD or PFM type) of two types, namely, about 10 kinds of specifications. Common Crusher for mineral processing, chemical, cement, construction, refractories, ceramics, glass and other industrial sectors crushing medium hardness ore, rock and slag, etc., which are generally used as the single rotor and finely chopped, double rotor used as a single-stage crushing and crushing. Coal crusher is mainly used for power plant and a coal mine, generally only a single rotor. Our crusher factory mainly on heavy, heavy, heavy, built, Dahua heavy machine towards heavy, heavy mine, Mine, Shenyang Machine, universal mining machine, South mine, mine, Zhejiang, Jiangxi and other mine . Which manufacturers are the most and the largest production-type impact crusher PF1007, reasonable structure, good performance, can be widely used in a variety of medium hardness materials broken. gold crusher and separater : Many gold containing sand cemented mud pie, and some of its particle size greater than 100 mm, this mud pie, if not crushing, screening process will be excluded together with waste rock, resulting in the loss of gold. In addition, on the clay but also cemented gravel or pebbles, if not crushing losses have gold in the screening process. Gold placer material is less than 0.1 mm is generally free of gold or gold minimal. Less than 0.1 mm gold commonly known as floating gold, difficult recovery in the sorting process, while the same level of slime Quedui grain sorting process, particularly mechanical sorting process from interference. So, in the gold placer mechanical plant, always trying to be less than 0.1 mm slime off. Desliming production equipment commonly used for a variety of off the mud bucket. The chute allows the material with gold grain size width and processing capacity, thus sorting sulfur tank do not take off until the mud. Practice has proved that the re-election law dealing with gold placer most effective and economical way. Due to the different grain size gold placer gold, and a variety of effective grain size limits re-election materials handling equipment is different, so a reasonable gold placer sorting process should be a joint operation of several re-election equipment.
