One main factor of impacting the belt conveyor service time is the conveyor belt quality. Therefore high quality of conveyor belt is required in purchasing. Another main factor is that the sweeper is highly reliable to make sure no more material adhered to the return belt, in case they are next sent to the surface of the drive pulley and bend pulley, thus bring damage to the belt and shorten its service time:
Due to how to greatly expand the service time of the belt conveyor, Followings are some suggestions:
- Avoid belt slipping on the drive conveyor pulley. Please find the reason and give prompt adjust if slipping appears.
- Check the conveyor belt joints frequently. Damaged conveyor belt joints should be repaired or replaced in time.
- Check the service condition of the belt conveyor roller regularly. Properlubricating grease should be added into the sealing machine in the maintenance, and also inflexible rotating rollers should be replaced immediately.
- High quality of lubrication should be added into all rotating parts of belt conveyor periodically according to the requirement.
- Ensure the good work condition of the cleaning device and replace damaged parts in time.
- Regularly check the conveyor belt tensity. Prompt tension is needed if the belt is loose. Meanwhile please notice the belt position, timely adjust should be made when it’s off tracking.
Belt conveyor is a kind of continuous conveying equipment. Can be widely used for quarry, coal, steel, chemical and other kinds of industries. Operating the belt conveyor safety, not only can make sure the safety of the operator, but also can longer the service life of the belt conveyor. PK machinery will introduce the safety operation regulation of the belt conveyor:
- The belt conveyor should start without load and should not feed material until it operating regularly. Forbidden feed the material before starting.
- Fixed belt conveyor should be installed on fixed foundation. Before the mobile belt conveyor operating officially, wheels should be holdback through triangular wedge or brake. To avoid move during operating, there should be an 1 meter channel between each machine if multi-set belt conveyor operating parallelly.
- Before using the belt conveyor, we must check whether all the moving parts, belt buckles and bearing device is normal or not; whether the protective equipment is completely or not. Belt tensioning degree should be adjusted to the appropriate level before starting.
- Forbidden stand on the conveyor belt.
- If multiply sets belt conveyor connection with each other one by one, we should start the one in discharge end first, then start the other sets according to their order. You can feed the material once all of the equipment operating normally.
When using the belt conveyor, less daily check and maintenance or do not pay attention to maintenance will greatly reduce the service life of the belt conveyor, when the belt conveyor problems occur, it will affect the work efficiency, so regular inspection for belt conveyor parts is needed.
Daily check
Mechanical items: inspect the guardrail, bridge, roller, pulley, turnabout pulley and belt.
Electrical items: inspect the anti-skid device, deviation switch, emergency stop switch, tear detection device, anti-reverse device.
Weekly check
Mechanical items: inspect the driving wheel, guide wheel section, reducer, inspect the machine's tail, check tensioning device and pull rope device.
Electrical items: inspect the main motor, inverter, filter, repair and inspect the main transformer wiring, electrical control, power system.
Monthly check
Mechanical items: inspect the rope wheel, transition wheel, guide wheel, driving wheel, belt wheel, tensioning car and check the oiling.
Electrical items: inspect the fastening bolts, fast switch; the maintenance and repair of commutator, limit protection, emergency stop protection and the alarm system.
