Joint Methods of Conveyor Belt

The most common joint methods of conveyor belt are mechanical joint, cold bonding joint and heat vulcanization joint. Here PK Machinery will discuss three different joint methods with you.

1.Mechanical joint

This joint method is to use belt fastener to connect belt. The most obvious advantages are convenient and economical. But this method has lower efficiency and it’s very easy to damage and reduce lifespan of conveyor belt. To connect PVC or PVG anti-flaming and anti-static belt, it’s very universal to adopt this kind of method if the conveyor belt grade is less than grade 8.

2. Cold bonding joint

This joint method adopts binding agent to connect belt. It is with higher efficiency compared with mechanical joint. What’s more, it can save investment cost. But in fact, due to the uncontrollable technological conditions and quality of binding agent, this kind of method is not very stable.

3.Heat vulcanization joint

It has been found that this joint method is the most ideal way to connect belt. It can not only   guarantee the joint efficiency and stability, but also can be easy to master and prolong lifespan  of belt. But it also has disadvantages of troublesome technology, high cost, long joint operation time, etc.

Selecting Methods of Belt Conveyor Roller

How to choose the right roller for the belt conveyor, the method are as the follows!
1.The abrasive and corrosive materials
2.The installation of the supporting roller of the equipment working conditions
Abrasive materials, such as clay, granite and black minerals may be on supporting and selection of important influencing factors, selection of wear resistant materials. To transport corrosive materials, such as salt and chemicals and need to choose resistance to corrosive materials of roller. In steel supporting roller coating or is selection of resistance to corrosion of high roller. Harsh environmental conditions especially in dusty conditions (cement, limestone, the ash) roller to have the best sealing system, provide the highest possible protection is necessary.

Daily, Weekly, Monthly Belt Conveyor Check&Maintenance Work

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.
