PF Series Impact Crusher is absorbing foreign advanced technology, combined with domestic sand and gravel industry specific mining conditions and the development of the latest generation crusher. It uses the latest manufacturing technology, the unique structural design, processing was finished cube, no tension and cracks, grain shape is good, can crusher feed size of not more than 500mm, compressive strength no more than 350MPa of various coarse, medium and fine material (granite, limestone, concrete, etc.), widely used in ore crushing, railway, highway, energy, cement, chemicals, construction and other industries for a variety of medium hardness materials for secondary and tertiary crushing, such as: limestone, clinker , slag, coke, coal and so on. Its particle size can be adjusted discharge, broken specifications diversification.
PF impact crusher works
PF impact crusher mainly consists of frame, rotor, drive mechanism, the back plate of several components.
Crusher is a use of impact energy to break material of broken machinery. First, the material from the feed inlet into the machine crushing chamber, driven by the motor, the high-speed rotation of the rotor, then the material falling from a height, coinciding with the machine rotor high-speed collision, the material into the plate hammer area, and board hammer rotor impact crusher, and by the broken material also acquire kinetic energy from the collision of the rotor, high speed toward the broken plate counterattack, counterattack and then from playing board Back plate hammer again crushing area, this process is repeated, the material descending into the chamber repeat counter crushed promptly discharged from the discharge port, thus completing the entire crushed back-breaking job, impact crusher is divided into two chambers and a three-chamber type, is broken after the material through the vibrating screen to match the required particle size sieve out, does not meet the requirements of the material is returned to continue crushing impact crusher, this closed loop, to complete the crushing operations. Gap adjustment between the impact rack and rotor material change to reach the expected size and shape of the material object.
Advantages PF counterattack crusher
1, the feed opening, high crushing chamber to meet the high material hardness, block degree, the product powder less;
2, the back plate and the board hammer gap can be easily adjusted, effective control of the particle size after crushing product was cubic shape, particle shape is good;
3, compact structure, machine rigidity, the rotor has a large moment of inertia;
4, high-chromium plate hammer, impact resistance, abrasion resistance, mechanical wear small, the impact force;
5, using the new rotor, increasing the impact force;
6, full-function crushing, crushing ratio, high productivity, low energy consumption and high overall efficiency.
7, expansion sets connected, simple structure, easy maintenance, economical and reliable.
