At present, there are various crushers and the crushers can be classified into extrusion type, impact type, shear type according to the main crushing force. Extrusion type crushing machine mainly comprises rotary crusher, roll crusher and so on. Its working principle is: materials crushed by the extrusion, splitting and bending force between the crushing mechanism fixed tooth plate and the movable tooth plate. This kind of crusher mixed crush materials in the crushing cavity, which is vulnerable to the formation of pulverization and easy to form the big shape product, which can't ensure product particle size and with a large power consumption. This kind of crusher is mainly used for crushing hard materials in metal, mining, gravel field and other industries. Impact type crushing machine mainly comprises impact crusher etc. This kind of crusher crush the coal by impacting with the hammer, after every impacting, the materials accelerating, then flying to the impact plate, shock, anti - shock, repeated by the same process, at the same time the materials after being hit mutually impact in the crushing cavity. This kind of crusher is difficult to control and which finally will lead to a mount of powder coal. It is worse to use this kind of method to crush the coal with higher fragility and lower hardness and it is strict with the size of the feeding. This kind of crusher is suitable for coarse and medium crushing materials. The crushing process of the key process in the coal dressing process and is also the important means to improve the technical and economic index of the coal dressing plant. Various forms of broken equipment, because of their different crushing mechanism, has different applicable scope and use. Choose a suitable crushing equipment you should according to the material properties and operational requirements. Accordingly, it is that different forms of crushing machine, because of its crushing principle is different, have different scope of application. Technological advancements have made coal mining today additional productive than it has ever been. To keep up with technology and to extract coal as efficiently as possible modern mining personnel must be highly skilled and well-trained in the use of complex, state-of-the-art instruments and equipment. impact crusher: Jaw breaker: Vibratory feeder:
