Impact Crusher is to use high-speed impact hammer plate and back plate of the rebound effect, so that materials and broken by repeated mechanical shocks. Hammer solid plate installed in the high-speed rotation of the rotor, and along the crushing chamber by a number of pieces of different angles back panel layout.
Materials into the role of board when hammer by the board before the first impact hammer and broken the first time, and at the same time kinetic energy, high-speed into the back plate. Back plate materials and broken again after the collision, the hammer bounced back to the role of the district board to reconsider the impact hammer by the board. So repeatedly until they were broken into and the required size from the plane. And the hammer crusher compared to counter-attack crusher greater than broken, and can make better use of the entire rotor high-speed impact energy. However, due to the wear plate can easily hammer, it shattered in the application of hard materials is also limited, often used to rough broken, or the chronology of broken limestone, coal, calcium carbide, quartz, dolomite, sulfide ore, gypsum and chemical raw materials in the following hard-brittle materials.
