Vibrating Screen Problems Solutions

Vibrating Screen Problems Solutions

Vibrating screen is mainly used for sand and gravel quarry screening material, but also for coal preparation, mineral processing, building materials, electricity and chemical industries for product classification purposes. Fault and treatment shaker more and more valued user, our common vibrating screen problems solutions are analyzed as follows: Shaker can not be started or amplitude is too small, you should check with Accessible, electrical motor for damage or lines component damage, whether under voltage, these three had no problems, and then check from the mechanical, material vibration sieve surface is stacked too much, if that is clear. Coupling bolt on the exciter without loss, whether the grease thickens agglomeration, then you can clean maintenance exciter, and then adjust the position of the eccentric shaft heavier block or Vice eccentric.

Vibrating screen problems solutions sieve surface material flow abnormalities, one screen box stiffness insufficient, there is a critical frequency, coupling bolts are loose vibration, even to the extent of overall vibration loose, that is tightened. Second transverse horizontal screen box did not identify, from the support leg spring bearing seat or the spring itself to find fault, for the spring seat or change the size, there may be damage caused by the screen surface network, as long as the replacement of the screen can be. If you have been due to lack of screen box stiffness, did not identify the horizontal level will cause beam fracture, is still operating as also make the material flow abnormalities. There may be improper operation, feeding extreme imbalance that is also one of the reasons. Vibrating sieve poor quality due to improper operation and more responsibility, may mesh plug into the sieve material in the fine increase and water increased, so that the oversize material layer is too thick, feeding inequality and so on. On both sides of the screen may pull Debu tight, if eccentric axle may belt drag weakness in the belt is too loose, and other mechanical problems dealt with, you can reverse spin for some time, in order to improve screening quality.

Vibrating screen although not very important to sand production line equipment, but is also essential, Vibrating screen for screening the sand transport in sand production line has to undertake the role, but sometimes there will be unable to start vibrating screen failure our engineers shaker reason we can not start the next. First look is not the power failure. Look at the current situation of the motor, if the motor is fault to be replaced with a new motor parts on it; shaker assembly line work is a combination of centralized control circuit, when certain elements of damage to the timely replacement of the element; sometimes voltage unstable and start voltage is lower than the rated voltage, ensure shaker during operation of voltage stability.

The most common is the exciter fails, we must first understand the working principle of vibrating screen, which is a principle by vibration exciter implementation of screening material, when the exciter failure can not be normal power operation also makes equipment not normal start, while the exciter member work to ensure good lubrication, not only professional and efficient but also to prevent grease thickened grease solidification occurs agglomeration, achieve its proper lubrication to check and replace the exciter lubrication suitable lubricants.
