How to exclude Mine shaker fault?

[ print ] [ collection ]   Relative to China crusher, our situation is not much change in the following we will explain your vibrating screen with the following characteristics:

A mining shaker (mining screens) can not be started or the amplitude of small
Approach: Check the electrical barrier-free motor for damage, whether the voltage is low; such as there was no problem, you can check from the machinery, see mine using a vibrating screener whether the accumulation of too much material, is clear; cleaningrepair the exciter, and appropriate adjustments to the eccentric shaft heavier block or Vice eccentric position.
Two, mine (mine shaker with sieve) noise
May be bearing damage, loose bolts, beams break, and spring damage, apart from the bolt can be tightened, the other three conditions need to be replacement parts.
3, the mine shaker rotating slower (mining Screening), bearing the heat
Causes and treatment methods: the maintenance of peace did not keep up with the bearing lack of grease, if it is new and added fats, is the quality problems or too full of fat, low-quality oil bearings so that blocking the labyrinth seal jam, so the grease The quality is very important.
4, the mine shaker (mine screen) side panel cracks, beams fracture, structural damage
Not suddenly such a situation occur in the critical frequency of long working hours, there may eccentric block of each block of the weight error is too large, causing structural damage, siding cracks, and even beam fracture, replacing the damaged parts. Tighten the bolts, the patch wallboard crack necessary to prevent crack extension, do not forget a few vents in the supplement to strengthen the board, board to play in strengthening the two hit two 6m / m holes.
(Mine, mining shaker with sieve) screen surface material flow abnormalities
Causes and treatment methods: lack of stiffness of the screen box, there is a critical frequency, coupling bolts vibration loose, even to the full extent of vibration loose fastening; horizontal screen box got the right level of support from the supporting leg spring seat or spring find itself wrong, change the spring or to change the bearing size, may also cause the screen surface network damage, as long as the replacement of the screen can be. Been due to insufficient stiffness of the screen box did not identify the horizontal level, will cause the beam fracture, is still operating also make the material flow abnormalities. Is also possible that improper operation, feeding extreme imbalance is also one of the reasons.
6, the mine using a vibrating screen (mine sieve) poor quality of screening
Reasons: improper operation; mesh blockage, increase the fine increase and water into the screen material, the sieve material layer is too thick; uneven feeding. The screen on both sides of tension; mechanical problems are dealt with can come to a period of reverse rotation, in order to improve the quality of screening.
