Main purpose:
The maximum compressive strength of the impact crusher can reach 350 MPa, which has the advantages of large crushing ratio and cubic particles after crushing. It is widely used in building materials, ore crushing, railways, highways, energy, transportation, cement, mining, chemical industry and other industries for medium and fine materials.
Applicable materials:
The impact crusher is mainly used in metallurgy, mining, cement, chemical industry, refractory materials, ceramics and other industrial sectors, as well as highway construction, water conservancy projects, construction sand and gravel, machine made sand processing and other fields. Due to the characteristics of its vulnerable parts, the application of the impact crusher in materials with high hardness is limited. It is more suitable for coarse crushing, medium crushing and fine crushing of various soft and medium hard ores, such as limestone, feldspar, calcite, talc, barite, rare earth, clay, kaolin, dolomite, gypsum, graphite, etc.
Application field:
It is widely used in mining, metallurgy, building materials, highways, railways, water conservancy and chemical industries. It is mainly used in metallurgy, mining, chemical industry, cement, construction, refractory, ceramics and other industrial sectors for medium and fine crushing of various medium hard ores and rocks.
working principle:
The impact crusher is a crushing machine that uses impact energy to crush materials. When the machine is working, driven by the motor, the rotor rotates at a high speed. When the material enters the action area of the plate hammer, it collides with the plate hammer on the rotor and is broken again. Then it is thrown to the impact device and broken again. Then it bounces back from the impact lining plate to the action area of the plate hammer and is broken again. This process is repeated. The material enters the first, second and third impact chambers from large to small and is broken repeatedly until the material is broken to the required particle size and discharged from the outlet.
The stones directly fall into the high-speed rotating turntable from the upper part of the machine. Under the effect of high-speed centrifugal force, they collide with the flying rocks around the turntable in an umbrella way to produce high-speed impact and high-density crushing. After the stones hit each other, they will form eddy current movement between the turntable and the casing, resulting in multiple blows and crushing. The first crusher is usually the "main" crusher.
