Euro counterattack broken as a use of impact for ore crushing of large and medium-sized crushing equipment, is more and more widely used in building material, metallurgy, mineral processing, chemical industry, etc. The euro back broken particularly suitable for crushing medium hardness brittle materials, it can be used to break limestone, coal, iron ore, sandstone, cement clinker, aluminum ore, molybdenum ore and other materials of coarse crushing, crusher, finely. Due to the euro counterattack crusher crushing effect is remarkable, in some small and medium-sized factories and mines, alternative broken jaw broken machine, roller crusher and cone.
Euro counterattack break the points for attention during the maintenance:
(1) the euro counterattack crusher operation in the process of routine inspection should be done regularly, when found to have abnormal sound or bearing temperature higher than 700 c, it is necessary to stop the machine immediately to check and eliminate the fault in time before I can continue to boot.
(2) after the machine working normally feeding, feeding wants even, should prevent iron with hard objects. Must stop feeding before stop, stop within the material is broken and then power motives.
(3) the counterattack broken after repair or adjust the discharging mouth, should first turn the rotor by manpower, confirm rotor and other parts without friction and sticking phenomenon and flexible rotation, can start the motor.
(4) should always check whether the bearing seal is good, bearing grease should be filling every month, every three months shall all be clean oil change and replace felt.
(5) check whether the fastener is loose, check should focus on the rotor side compression screw of clamp plate hammer, prevent loose pressure plate, plate hammer at both ends with daughter, and the body touch attack, damage to the parts.
(6) to ensure that the operating personnel and equipment safety, are prohibited in machine repair, adjust and clean up, forbid to open the door.
(7) when broken product particle size is too large, should stop check board hammer wear, to prevent the rotor is worn. When the board hammer adjust 180 due to wear and tear. Again, when using, should make every board hammer equal in weight and balance, to prevent vibration in the aftermath of the machines on.
Euro back to break the application
Euro counterattack plate hammer and the rotor is rigid connection, and there is a large crushing cavity, the material has a certain activity space. The impact crusher materials to make use of high-speed rotation of the rotor, the hammer plate under the action of the material not only is broken, also get larger velocity and kinetic energy, the rack of the impact plate impact crushing the lumen, or as the impact between each other between pad material crushing. As early as 1965, by the design and research institute of anshan coking refractory to counterattack crusher crushing coking coal feeding experiment. And with cage crusher and hammer crusher production capacity, power consumption, maintenance and maintenance aspects of comparison. Through the experiment, break in the above aspects are better than that of the cage crusher and hammer crusher. Counterattack crusher not only has simple structure, energy saving, big crushing ratio, and more has unique advantages in product granularity. So it’s in metallurgy, coking, chemical industry, building materials, refractory materials and other industrial sectors has been widely used.
