PF series counterattack crusher (counterattack broken) well broken side length less than 500 mm, less than 350 mpa compressive strength of all kinds of coarse, medium and fine materials (granite, limestone, concrete, etc.), widely used in all kinds of ore crushing, railway, highway and the production of artificial application of construction industry. This series of counterattack broken is Liming heavy industry in absorbing advanced technology at home and abroad, combined with the mining situation and development of sand industry domestic newest counterattack crusher.
PF counterattack break working principle:
Working principle of counterattack crusher and hammer crusher are basically the same, they are using the high speed impact crushing material, but each have differences, structure and working process of the following is counterattack crusher working principle.
Counterattack crusher as the main working parts with high-speed rotor plate hammer. Feeding crusher materials inside the rotor rotation range (hammer), plate hammer shock; And high speed into the counterattack plate, hit; Then from bounced back plate to plate hammer, repeat the above process. In such a process, back and forth between material and collide each other. Stuck in between the back plate and plate hammer material, by high speed rotating hammer plate milling effect. Because the material is plate hammer blow, impact on the back board, materials and plate collision between hammer milling effect of material makes the expanding of the cracks in the material and produce new cracks, eventually leading to pieces. When the particle size is smaller than the gaps between the back plate and plate hammer was discharged.
Counterattack broken application features:
Counterattack crusher processing material adopts the way of fractured shatter, application characteristics of the equipment is mainly manifested in the following aspects:
(1) broken high efficiency. General materials. Strike just tons of 1/10 of the counterattack crusher for crushing the material with high efficiency, the materials of the broken unit power consumption is only part of the jaw broken machine l / 3, so the machine production capacity big, broken than large, small energy consumption.
(2) broken than high. Can be up to 30 a broken than 40, equivalent to a coarse crushing, crushed in the crusher series, or series of crusher, fine crusher. So a mechanical can be used for two ordinary crusher series, so as to simplify the procedures and processes.
(3) counterattack crusher structure is simple, reliable operation, easy to operation and maintenance.
(4) is suitable for crushing hard materials processing, unfavorable processing hard and sticky plastic material.
(5) crusher plate hammer and counterattack plate wear big, change need regular maintenance, to adjust balance board hammer replacement.
6 crusher work noise, dust produced more.
