Therefore, DMS methods are widely used in the separation of coal and various metal ores and nonmetallic ores. Direct separate clean coal and waste rock; separate coarse waste tailings and rough concentrate. For the ordinary gravity separation method, the lower limit of the feeding ore is about 23mm (the coal is 36mm).

Coal Crusher Types Impact Double Roller Crusher. Coal crusher, also known as double stage crusher, is a highly efficient crushing equipment. It is a new type of equipment developed for the coal industry, and it mainly crushes high moisture coal. Besides, it is mainly used to crush coal cinder, slag, shale, coal gangue and other materials.
In large coal preparation plants with a capacity of 30 million tons/year, the belt speed can reach 7 m/s and the thickness of the material layer can reach 500 mm. Therefore, in highthroughput and complex environments, the problem exists that harmful feeding materials such as iron and gangue are not easily detected, and thus fault diagnosis in the crushers lags behind.
