used hammer crushers

Our high-efficient fine crusher, a kind of crushing machinery, can make finer sand than ordinary sand making machines. The machine is a patented product developed on the basis of our former sand making machines, and can fully satisfy market requirements. Currently it is extensively applied in the field of sand making, building materials, metallurgy and chemical etc. Our impact crusher is a new type of high-efficiency crushing equipment. This crusher mainly consists of board hammer, impact plate, board hammer pedestal, rotor, and feed port etc. Being simple, reliable and energy-efficient, our impact crusher is one of the most frequently used rock crushers. impact crusher is ideally suited for breaking materials with a grain size of not more than 300mm and compressive strength of not more than 350 MPa. It can crush materials of all hardness, being an ideal piece of equipment for secondary crushing. The crushed materials with a cubic shape are widely used in the construction of highway, railway, airport, and others. Additionally, our impact crusher has obtained U.S. patent. Impact Crusher Performance and Features 1.Large feed port, deep crushing chamber, high reduction ratio (20:1). 2.Non-key connection, compact structure, reliable performance, easy operation, simple maintenance. 3.High-chrome flat hammer, wear resistance, great impact force, long life. 4.The gap between the impact plate and flat hammer is easy to adjust, so the discharge size is effectively controlled. Impact Crusher Working Principle Impact crusher involves impact to crush material. During operation, the rotor driven by the motor performs high-speed rotation, and the flat hammer installed in the rotor collides with the entered material, later the material is thrown to the impact plate to realize crushing again. With the material repeatedly being thrown to each impact plate, crushing is continuously carried out in the impact chamber, and the material will be discharged when the required size is achieved. The size and shape of the material to be discharged can be adjusted by adjusting the gap between impact rack and rotor rack. During operation, the motor drives the eccentric shaft shells to turn around through a horizontal axle and a pair of bevel gear. The axle of crusher cone swings with the force of eccentric shaft shell so that the surface of the crusher walls is close to the roll mortar wall from time to time. In this way, the ores and rocks will be pressed and crooker and crushed. Cone crusher is suitable for mid-hard rocks and ores, such as irons, copper ores, limestone, quartz, granite, gritstone, is suitable for mid-hard rocks and ores, such as irons, copper ores, limestone, quartz, granite, gritstone, etc etc. Type of the crusher cavity is decided by the application of ores. Standard type for PYZ (secondary crush), middle type is for PYD (tertiary crush); short-head type is for primary and secondary crush. CY Series cone crusher features high productivity, high quality, less machine stop tine, easy maintenance, low cost as well as unique crusher ability in primary, secondary and tertiary crushing. Frequently used hammer crushers are drying hammer crushers and ring hammer crushers. Xuanshi is a professional stone crushing machinery manufacturer in China. We primarily produce ring hammer crushers. Our hammer crushers are widely to crush medium-hard friable materials (water ratio ≤ 15%, compressive strength ≤100 MPa). Xuanshi hammer crushers are mainly used to crush coal, salt, chalk, gypsum, brick and limestone. Besides, our stone crushers can also be used to break fiber structure, broken wood, paper, as well as asbestos and cement waste. Currently our hammer crushers are increasingly used in the area of mining, cement, coal, metallurgy, building materials, highway and so on. The motor drives the rotors to rotate quickly in the crushing chamber. Materials enter the crusher through the feed port, and then they are being stricken, cut and ground into smaller particles by a hammer. There is a sieve plate under the rotor, so the materials whose size is smaller than the sieve size will be sieved out and others will be left to be further stricken and ground until they can be sieved out. The size of final product can be adjusted by changing the sieve plate. The gap between the rotor and the sieve plate can also be adjusted according to different requirement.
