Impact Crusher Overview: Impact crusher, a kind of new type high efficiency crusher machine, is generally used in the secondary crushing and can be widely applied to the industries of highway, railway, mining and metallurgy. It can be used in crushing of raw materials whose comprehensive strength is no more than 320 Mpa, such as limestone, granite, gypsum, etc. Impact Crusher Features: 1.Uniformly broken multi-cavity, improving production capacity and saving energy; 2.High chromium new type wear-resistant blow bar, unique toothed impact plate; 3.Shape optimizing function makes the final product cubic; 4.New Design of low speed and multiple crushing cavities sets the rotary speed down by 20-25% and obtain high production capacity under lower energy consumption. Working Principle : Impact crusher utilizes the impact energy to crush materials. Under the drive of motor, the rotor, with the blow bars, keeps in the high-speed rotation. When the materials fall into the affecting area of rotor, They will be stroke by blow bars and be thrown to the impact devices. Then the materials are rebounded to the working area of rotor for crushing again. The high speed forces the material to rebound from the impact liner to the area where the blow bar effects until they have been crushed to the required size. The gap between the impact rack and the rotor can be adjusted to change the size and shape of the finished product.
