The Impact crusher is used in secondary crushing of material, and the impact crusher processes various kinds of material with crushing compression strength not more than 350 mpa, featuring firm structure, stable performance, large capacity, even producing granularity ,convenient maintenance and economical running expense, and widely applied in the areas of mining ,construction material,smelting, railway, highway, water conservancy, etc. The hammer crusher hammer was hanging condition, wear and tear occurred, the front and rear and side, relative to the plate hammer, hammer wear and tear is more serious, hammer metal utilization ratio is only about 25%. And the rotor body itself may be subject to wear and tear. Hammer Mill wear seriously affected by the bottom of the sieve-plate, grille should all replace, and replace the sieve of the work more complicated.
When the materials enter the field of the hammer, it is impacted by the hammers, thrown onto the impact plate, and crushed. The stuff springs from the impact plate, is impacted by the hammers again, and thrown onto impact plate. This process will last until the stuff meets the requirement and falls from the machine. Adjusting the distance between impact frame and rotor frame can change the shape and size of the output. When some foreign stuff enters the machine, the impact frame will fallback, the stuff falls from the machine. This device can prevent machine from damages.
The Impact Crusher Machine rotor revolves in fixed direction by means of driving action of triangle belt that connects with motor. Above rotor, there are two sets of suspended impact plate. Material enters into rotor through charging hole and feeding guide plate. The plate hammer fixed on rotor strikes onto impact plate and then fall from it to mutually shock material blocks that are successively delivered upward by rotor. Therefore, material block will be moved recurrently and repeatedly in the crushing chamber that is composed of rotor, impact plate, guide plate and chain curtain, by means of which intense shock phenomenon will come into being, and the material block will be crushed along its natural crack or concave and bulge.wet magnetic separator:http://www.hx-crusher.com/magnetic_separator.html
The Impact Crusher Used for mineral dressing, chemical, cement, building, refractory materials, ceramics, glass and other industrial sectors in intermediate crushing and fine crushing of diversified medium hard ore, such as limestone, calcined lime, clinker aggregate, slag, cullet, calcium salt, crude ore, building material, coke, coal, etc.
Broken rotor only counter to install six panel hammer, special tools can be easily board hammer replacement, the replacement of a board of only one frequency hammer time. The bottom of the grinding chamber grinding rod replacement also requires only several minutes, greatly reducing the repair and maintenance time and costs. The hammer crusher hammer up to more than 100, with the replacement of a hammer to spend a lot of time and manpower, repair and maintenance costs higher. The bottom of the screen plate and its replacement is also troublesome.
