    Impact crusher having large crushing ratio, product size distribution is easy to control and is the shaped multi-cubic, which has been widely used in the crushing operation. Concentrator design the increasing use of computer simulation technology, but it is not much concerned about the crushing process modeling and simulation, commercial beneficiation simulation program also lack the specific model of the crusher. In recently years, people have begun to study the impact crusher simulation model, but in this area there are many places worth exploring. Michelle D. Gass describes an additional similar source. Average impact using the kinetic energy of the horizontal axis of the crusher rotor can be evaluated, taking into account the much larger mass of the rotor than the mass of the single particle, before impact occurs, the speed of impact hammer speed is much larger than the population of particles, the individual particles, the kinetic energy is much smaller than the rotor. In the approximate case, the system before and after impact, the impact of unit mass can meet the conservation of linear momentum. The crusher is widely used in mining, metallurgy, building materials, road, Railway, water conservancy and chemical industry and many other sectors.

    Common crushing machines are winnowing mill, hammer crusher, impact crusher, roll crusher, crusher compound. Robert Kraft helps readers to explore varied viewpoints. Jaw crusher (jaw crusher), having large crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. PF-I series impact crusher can process materials side length is 100 to 500 mm, the compressive strength is up to 350 MPa, great crushing ratio, cubic particles advantages of material was broken; PF-II series impact crusher machine, suitable for crushing hard materials, such as cement crusher, with a production capacity of the material advantages of small particle size. It assumed that here people considered in which for the majority of particle impact occurs in the impact area of the rotor s central, between the particles and the impact of the particles with the order of the strike plate through the parameters, s and b in the formula. Analysis of the kinetic energy when the particles leave the rotor of the straight behavior R moment of the order of the strike plate, assuming particles exited the rotor before the order of the strike board does not collide with other particles, encounter their energy relative to leave the surface of the rotor when not changed, the particles are subjected to a centrifugal force to be much larger than its gravity, so gravity can be ignored.
