Repair methods for vibrating screens

When problems are found during regular inspections of the vibrating screen, the vibrating screen should be repaired. The repair content of vibrating screens includes timely adjustment of the tension of V-belts, replacement of new belts, replacement of worn screen surfaces and longitudinal spacers, replacement of vibration damping springs, replacement of rolling bearings, transmission gears and seals, replacement of damaged bolts, and repair of damaged screen frame components, etc.

2. Stress concentration should be avoided on the side plates and beams of the screen frame. Therefore, welding is not allowed on these components of the vibrating screen. When the lower crossbeam of the vibrating screen cracks, it should be replaced in time. When cracks are found on the side plate, a 5mm hole should be drilled at the end of the crack in time, and then a reinforcing plate should be added to the cracked area. The disassembly, repair and assembly of the exciter should be carried out by dedicated personnel in a clean place.

3. After disassembling the vibrating screen, check the wear of the rolling bearings, inspect the gear tooth surfaces, check the connection of each component, clean the lubrication circuit in the vibrating screen box to ensure it is unobstructed, remove the attachments on each mating surface, and replace all seals and other damaged parts.

4. Special attention should be paid when maintaining the vibrating screen

(1) The disassembly of the exciter and transmission device should be carried out by experienced technical workers. Rough operation of the vibrating screen is strictly prohibited to prevent damage to the equipment. The parts of the vibrating screen should be kept clean before assembly.

(2) The new screen mesh of the vibrating screen after replacement should be re-tensioned every 4 to 8 hours until it is fully tensioned.
