Maintenance Work for Belt Conveyors

Maintenance Work for Belt Conveyors

When it comes to actual operation of belt conveyor, if there is less maintenance, it will greatly reduce its lifespan. There is no doubt that belt conveyor occurs problems will seriously affect work efficiency. So it’s necessary to maintain components of conveyor belt timely.

Daily Care

Mechanical items: check guardrail, rollers, pulley, bend pulley, belt

Electrical items: check anti-skid device, belt sway switch, tear detection device, anti-reverse device

Weekly Care

Mechanical items: check driving wheel, guide wheel, tension device, belt pull rope device

Electrical items: check main motor, filter, power control, power system; repair main transformer wiring

Monthly Care

Mechanical items: check all parts of rope wheel, transition wheel, guide wheel and belt pulley

Electrical items: check fastening bolts, fast switch, emergency stop protection and alarm system

Great Changes in Technology of Conveyor Belt

Great Changes in Technology of Conveyor Belt

With the development of scale of mine, belt conveyor has kept on towards large scale and presents features of large capacity and long distance. Belt conveyor with long distance and multi power has achieve successful research and development, it changes the single load-carrying way that is given by rollers and adopts multipoint electric drive. This method can address the traditional problems that are changing conveyor belts frequently and belt breakdown easily. Also, the successful development of this kind of belt conveyor can reduce the cost of equipment greatly. What’s more, its advantages are reducing thenumber of transshipment or fall of ore during operation and avoiding environmental pollution.

 

The successful development of belt conveyor with 1km-100km belt length, adopting multipoint electric drive which can reduce 10%-30% investment and operation cost. Especially, it can decrease belt strength and eliminate risk of tapebreak of upward transport belt conveyor with large angle and long distance. And then it can prolong the lifespan of belt more than 5 times. Multi-power belt conveyor not only can achieve the goal of lower investment, lower consumption and resistance, but also operate stably more than 10 years. In this way can it improve the running rate and economic benefit greatly.

Risks of Conveyor Belt Running Deviation

Risks of Conveyor Belt Running Deviation

The belt running deviation is rather harmful during the operation. Actually it will affect the efficiency of conveyor capacity and lifespan of belt. So it must  turn off the machine when the belt is off tracking.

The belt running deviation is rather harmful during the operation. According to the actual operation of belt conveyor, the deviation effects on the operation and production of belt conveyors are mainly in the following aspects: 

1. Failure breakdown emergency stop device

The failure breakdown emergency stop device with protective purposes is installed on the belt conveyor. When the belt deviation occur and near the failure breakdown emergency stop device, it will causes the device to stop the machine immediately, and hence causes the conveying process to stop. This will affect the efficiency of production line, and hence increase the cost of production. Some serious cases might lead the project unable to finish on time, or even causes the undesirable contract disputes. 

 

2. Reduce the life-span of main components

Firstly, the breakdown of roller, bearings and other mechanical components, such as belt running deviates from pulley will cause the increasing of the force of roller, and hence it will increase the probability of failure. Secondly, it leads the belt to be worn out in a shorter period. The belt running deviation cause the materials spread onto the return belt. It will cause the belt and roller encapsulate to wear and tear abnormally as the materials can’t be fully removed from the return belt. Thus, the life-span of belt and roller will be shorten. Thirdly, it leads the tear and wear from the edge of belt, if the edge of belt collides with frame for a long time during the operation, it will cause the severe wear of belt edge and thus affects the life-span of belt which will leads to the increase of maintenance cost and also the operation cost. When the serious belt deviation occurs, it causes belt tearing directly. Belt deviation might lead to serious overturning of belt, causing the increasing of unilateral force ,hence it will lead to belt transverse fracture.
