Brief Introduction
PF Series Impact Crusher uses the latest manufacturing technology, unique structural design, its end product is cube size, no tension and cracks, its grain shape is good, which can break particle sizes less than 500mm, compressive strength is no more than 350MPa medium, fine materials (granite, limestone, concrete, etc.), widely used in ore crushing, railway, highway, energy, cement, chemicals, construction and other industries on a variety of medium hardness material, it could crusher limestone, cooked material, slag, coke and coal. The particle size, specification diversification can be adjusted.
Compared with hammer crusher, this impact crusher offers larger crushing ratio, with full use of high-speed impact energy throughout the rotor, impact crusher is usually used for crushing, breaking limestone, coal, calcium carbide, quartz, dolomite, sulfide iron ore, gypsum and chemical raw materials under medium-hardness brittle materials.
This ideal feed size is 100-500mm; Fineness adjustment could be satisfied by the space between the hammer and impacting plate.
Features
1. Large feeding size, high crushing chamber to meet the high material hardness, large block, and less product powder;
2 Easy adjustments of hammer and impacting plate.
3. Compact structure, machine rigidity, the rotor has large impacting energy;
4. High chrome hammer, impact resistance, abrasion resistance, large impacting force;
5. A new type of rotor to increase the impacting force;
6. High productivity, low energy consumption, high overall efficiency.
7. Simple structure, easy maintenance and reliable.
Working Principle
PFP impact crushers are generally used as primary crushers for crushing quarry rock, which are designed for crushing low abrasive and medium hard materials. The materials fed to the crusher trough its large feeding opening are crushed in two stages while impacted by the rotor's hammers to the adjustable primary and secondary impact plates. The materials will not pass to the secondary impact plate until being crushed and reduced to the size which the primary impact plate is adjusted to and will not pass to discharging chute until being crushed and reduced to the size which the secondary impact plate is adjusted to. By this adjustable impact plates the maximum size of output material can be controlled.
