Linear Vibrating Screen: Usage Tips and Common Pitfalls

Precautions
The linear vibrating screen equipment utilizes the excitation of a vibration motor as the vibration power source. This makes the materials be tossed on the screen mesh while moving forward in a straight - line motion. Materials enter the feed inlet of the screening machine evenly from the feeder. Through multiple - layer screen meshes, several specifications of over - size materials and undersize materials are generated and discharged from their respective outlets. It is characterized by low energy consumption, high output, a simple structure, easy maintenance, a fully enclosed structure without dust dispersion, and automatic discharge, making it more suitable for assembly - line operations.

The screen frame of the linear vibrating screen has two types: wooden and steel. The wooden screen frame is convenient for screen replacement, yet it is prone to damage, so it needs to be checked frequently. Due to the large screening output of the linear vibrating screen, the wear and tear of the screen mesh and bouncing balls are relatively high, and they also require regular inspection.

Problems detected during the regular inspection of the linear vibrating screen should be repaired. The repair work of the vibrating screen involves promptly adjusting the tension of the V - belt, replacing the new belt, replacing the worn - out screen surface and longitudinal padding strips, replacing the damping springs, replacing the rolling bearings, transmission gears, and seals, replacing the damaged bolts, and repairing the damaged parts of the screen frame components.

The side plates and beams of the screen frame should avoid stress concentration, so welding is not permitted on these components. In case of the cracking of the lower cross - beam of the vibrating screen, it should be replaced promptly. When cracks are found on the side plates, a 5 - mm hole should be drilled at the end of the crack promptly, and then a reinforcing plate should be added at the cracked part. The disassembly, repair, and assembly of the exciter should be carried out by full - time professionals in a clean environment.

After the vibrating screen is disassembled, check the wear condition of the rolling bearings, check the tooth surface of the gears, check the connection of each component, clean the lubrication circuit in the box to ensure it is unobstructed, remove the adhered substances on each joint surface, and replace all the seals and other damaged parts.
