Impact crusher is a new high-efficiency mining equipments ,the character is small bulk , simple structure ,high crush ratio (can reach 40),save energy ,high productivity ,the product pranularity is equality ,and has the choice of the crush funciton,is a good future equipment . But the biggest disadvantage is hammer and the impact scaleboard are very easy to abade,especially to the hardest iron stone, the abasion is very heavy ,need to change . At present ,because of the last abrade material , it has used in the choosing mining .
PF impact crusher function:
The sesies machine can deal with the size under 100-500 mm material , compression strengh no more than 350Mpa.has the future of big crushing ratio , the finished material is solid .
PF impact crusher working principle :
Impact crusher is a use of impact energy to break material of broken machinery. When the machine works, under the driving of the motor, the rotor high-speed rotation, the material into the plate hammer action zone, and the rotor plate hammer crushing crash, and was thrown back device again, and then from the counterattack scaleboard bounced back plate hammer crushing zone again, this process is repeated, material from large to small in one or two, three back cavity is repeated until the material being broken broken, to a desired size, by the discharge port. Adjust the back frame and the clearance between rotor can change material material particle size and shape of the material. Stone by the machine top speed of rotation of the turntable to fall directly; under the function of high-speed centrifugal force, and the other part of the umbrella type shunt in the surrounding rocks produce high speed impact and high density crushing stone in, against each other, and the turntable and the casing is formed between the vortex motion caused by repeated 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.
PF impact crusher character
1, the backplane can withstand high rotor rotor moment of inertia and hammer impact crushing force.
2, the machine optimization design into a low speed, multiple crushing cavity of impact crusher, the line speed than the general strikes back broken lower 20%-25%, with low energy consumption and obtain high production capacity.
In 3, the machine has three broken and a shaping function, broken than large, product shape of a cube can be selectively broken etc..
4, rational board hammer structure, with loading and unloading fast, multiple transposition and other advantages, greatly shorten the time for board hammer.
5, a new manufacturing technology, successfully developed a high wear resistance, high toughness of chromium, molybdenum, vanadium alloy materials, to solve the hard material of broken problem. Greatly improving the service life of the plate hammer.
6, the unique counterattack tooth plate, keyless connection.
7, PFY1315 hard rock strikes back broken with a multifunctional hydraulic station, a hydraulic high-speed discharging gap, stable damping and impact plate body automatic opening function etc
