1.What are the crusher rotor main components ?
Rotor Mainly by the rotor shaft crusher, hammer, hammer shaft, sleeve, locking devices, bearings, bearing, seals, pulleys and other components.
2 where are mainly the crusher rotor danger zone ?
According to structural analysis by finite element stress analysis simulation can clearly see the cloud of broken rotor dangerous areas mainly in the hammer shank, hammer drive shaft hole hammer, hammer drive foreign aid, hammer shaft, spindle bearing shoulder elementary bit .
3.What are the major fault for the very old crusher rotor?
Crusher fault as follows: Hammer drive shaft hole and the outer edge of badly worn hammer shaft fracture, crack hammer plate, locking device failure, displacement of the spindle, bearings fever, severe damage to bearings, spindle deformation or fracture.
4What are the benefits of crusher rotor maintenance?
Crusher with high-speed rotation of the hammer, impact and peel crushed limestone mill, because the equipment at work for a long time by the impact and friction materials, inevitably composed of the rotor component wear, deformation, damage and loss of normal working capacity . If analysis of the rotor working status and life expectancy, so that planned maintenance, overhaul, once the emergency is caused by all production of the company’s losses.Regular maintenance can significantly extend the rotor rotor life, reduce the failure rate crusher, crushing machine to improve efficiency, can improve the crusher output.
5.How to fix the crusher rotor?
Hammer crusher hammer shaft, bent shaft inspection and repair straightening, locking device check the repair, the outer edge of the rotor hammer disk drive at the repair or replacement of hammer, hammer crusher hammer repair, replacement and grading, bearings, bearing Block, seal cleaning and maintenance.
6.how to select good crusher rotor?
Select crusher rotor mainly depends on what technology the rotor crusher designed for hazardous area is how to deal with, currently the best crusher rotor technology is the finite element analysis techniques. Now ,I will explain what the good crusher rotor choice should be payed attention to. Good crusher rotor has the following characteristics:
1) The use of advanced finite element analysis technology to effectively improve rotor design;
2) Rotor stress analysis based on the weak parts of the cloud, take high-quality reinforcement design and high-strength alloy steel;
3)The whole rotor surface tungsten titanium armor type protection design, the structure of thecrusher rotor body, greatly reducing the hammer and the end plate of the hammer plate stress concentration and enhance its strength, to effectively prevent the fracture , and can effectively prevent jammed crusher, the rotor can improve the life more than doubled.
4)With variable moment of inertia design, effectively improve the grinding efficiency and crusher production, lower fineness 20 to 30%.
5)Side plate and plate hammer on both sides of the hole around the thick shaft, and extends to the bolt holes around the thicker part of the rotary hammer has a convenient monthly alveolar, hammer directly on the plate and end plate mounted on the spindle connection string .
Different kinds of rotors
