Maintenance Instruction of Rotor of Crusher
Crusher is the common and important equipment in mineral production. So it’s necessary to do preventive maintenance of rotors of crushers. Let’s introduce the steps of daily maintenance taking hammer crusher as an example.
Forewarned is forearmed, without prejudging the waste. Rotor preventive maintenance can greatly extend the rotor using life, reduce crusher failure, improve the utilization rate of crusher and effectively improve the crusher production. What benefits can be got from preventive maintenance of rotors?
A) What are the main content of rotor hammer dish repair in hammer crusher are?
Hammer dish installation. The cooperation of key and keyway should be paid attention and checked and each hammer dish should be tightly fitted with each other. Lock device is checked and can be changed when necessary, to prevent hammer dish removing and spindle shifting.
B) For the excessive worn crusher rotor, what are the main faults?
The main faults of the hammer crusher are: hammer shaft hole on hammer dish and the outer edge are worn seriously, hammer shaft fracturing, hammer dish cracking, and lock device failure, spindle displacement, bearing heating, bearing damaged, spindle deformation and even rupture.
C) Why is there regularly rotor work analysis, life prediction and plan to overhaul maintenance?
In hammer crusher, the high speed rotating hammer will impact and crush and grind the limestone’s. For the equipments in long working time is bearing the impact and friction of materials, rotor members are worn, deformation, damaged and will lose the normal work ability, which is inevitable. If we don’t do regularly rotor work analysis, life prediction and do planned maintenance and overhaul, once emergencies appear, these emergencies will cause severe losses that all production will stop, which is so serious to the enterprises.ore rod mill:http://www.hx-crusher.com/n230.html

D) What are the main content of hammer repairing and gradation on hammer crusher are?
The main content of hammer repairing and gradation on hammer crusher are: hammer is the main work parts in hammer crusher. Hammer dish is divided into several parts along the circumference and equipped with N hammers. Adjacent hammer interlaced and the hammer can do full circle swinging in 360 degrees. When the front edge of hammer is worn to the two-thirds of width, the hammer can be turned over to be used again. The worn hammer can do bead weld antifriction alloy and save a large amount of metal material consumption.
