What is the Impact crusher?
PF Series Impact Crusher is a new product that absorbs advanced technologies at home and abroad. This Series equipment can crusher material which max feed size is less than 500mm, compression strength is not more than 320 Mpa (eg: granite, limestone, concrete etc.) With its excellent performance and good performance, Impact Crusher is widely used in highway, hydroelectric, artificial stone and sand, crushing and building material industry ect.
Impact crusher classification:
Impact crusher according to their structural characteristics can be divided into the single rotor impact crusher ( back broken) and double rotor impact crusher ( back broken). Rotor turning, single rotor impact crusher the reversible rotary and not reversible turn two big types. Double rotor impact crusher can be classified to rotate in the same direction, reverse rotation type and the opposite direction rotation type three types. According to the internal structure, single rotor impact crusher is divided again with even grate plate and without regularity grate plate two forms. Double rotor impact crusher can be divided into the rotor at the same level and the rotor is not at the same level in two forms.
Impact crusher how it works:
Stone from the machine top directly into the high-speed rotation of the turntable; under the function of high-speed centrifugal force, and the other part with umbrella type shunt in the surrounding rocks from a high-speed collision with a high density of crushed stone in, against each other, and the turntable and the casing is formed between the vortex motion caused many of the against each other, friction, crushing, from the lower part through discharge. The formation of closed cycle of repeated, by screening equipment control to achieve the required particle size. The crusher ( back broken) by high speed rotation of the rotor plate hammer for breaking into the cavity, the material to produce high speed impact and broken, and the broken material along the tangent direction at high speed into the crushing chamber and the other end of the back plate, was again broken, and then from the strike plate to plate rebound hammer, continue to repeat the above process. During the trip, the materials and clashing role. Because the material is plate hammer blow, and the counterattack plate impact as well as the material mutual collision, the material continuously produce cracks, loose due to crushing. When the particle size is less than the impact plate and the plate hammer when the gap between, was discharged.
Impact crusher technical characteristics :
、Multiple cavity is crushed, suitable for crushing hard rock, high efficiency and energy saving.
、Low and big feed port, convenient production line layout and increase the size of feeding material.
、The unique tooth type counterattack scaleboard, new wear-resistant materials so that the plate hammer, back lining and lining board with longer life.
、Full hydraulic open, easy to repair and replacement of wearing parts, product shape of a cube, nesting adjustable particle size, simplified crushing process.
Impact crusher working principle:
PF Series Impact Crusher use impact energy to crush materials. When the impact crusher works, the motor drives the rotor rotate of the impact crusher with high speed. When the materials get into the area which the hammers effect, under the impact function of the hammer at a high speed, the materials are thrown to the impact device above the rotor continuously. And then the materials are rebounded from the impact liner to the area where the hammers effects for being recrushed, then discharged from the discharge port. Users can adjust the space between Impact Rack and Rotor Support, and then get to the expected size.
Impact Crusher Features and Benefits:
、Simplify the Crushing process.
、Many cavity to crush, suitable for crushing hard rock.
、Hard stone crushing, high efficiency and energy saving.
、the shape of the products are cube, the discharge opening size can be adjusted.
、Hydraulic start-up which is convenient for maintenance and replacement of wear-parts.
、New anti-abrasive material which prolong service life of impact hammer, impact plate and liner.
、Low and big feed opening make the production line easy to arrange and increase the size of feeding material.
、High-chromium plate hammer, unique Impact plate, especially for hard rock crushing, high efficiency and energy saving.
、Reasonable design of leveling plate making the finished material finer and cubic-shaped without internal cracks.
