Making The Right Choice Of Conveyor Belts - Types Of Conveyor Belts

Factors Influencing Selection Of Conveyor Belts

Conveyor belts take care of a significant proportion of transportation mechanisms performed in mining operations. These simple yet vital components can alter the way materials get transported, greatly reducing time and boosting efficiency by appreciable margins. Just as for all functional components, there are a number of factors that influence just how effectively they operate.

Load Support

This is among the most crucial factors since conveyor belts have to convey tons of material in smooth fashion. There are chances of them getting forced over junction gaps within the idlers as belts get loaded onto trough idlers. This occurrence increases risk of premature failure, with the entire system of transportation getting compromised.

One way of reducing this incidence is ensuring that heavier loads end up travelling over belts that have smaller flex radius. It bridges the junction gap, thereby reducing risk of machine-failure. Belts must in addition be designed with higher flex life to enable them conform to diverse angles without getting forced into junction gaps.

Transverse Flexibility

Belts need to be rigid yet flexible sufficiently to maintain contact with tracks all of the time. A very high belt-shift risk exists if this fails to happen that could occasion damage to the entire mechanism. There is also an increased possibility of the belt derailing although this is not a common occurrence.

Impact Rating

Heavy and abrasive materials get transported during mining operations. The belts must thus be capable of withstanding these two factors. Opting for a belt with maximum working tension that is above the required proportion is one way of ensuring they do not suffer premature failure. This pushes up the equipment-cost but is a less costly measure than suffering impacts which it is not designed to handle.

Type Of Belt Material

Conveyor belts, get designed from different materials, with the most common being PVC, rubber and urethane. All these three kinds have their positive points and negative points in certain areas. A consultation done between manufacturers and engineers should decide what type is applicable for a given application function. Features like flame retardation ability have to be accounted for in addition to equipment for detecting and suppressing fire used in mining operations, although a majority of belts end up burning under intense heat.

Types Of Conveyor Belts

Portable, permanent, cable, shiftable and high angle versions are the main types of conveyor belts available. Permanent belts are utilized throughout the life of a mine as main lines and in slopes. Portable models are used commonly in surface mining, being fairly easy assembling and disassembling. Cable belts are customized for long-distance transportation and have the ability of negotiating long radius curves. Rope cables are normally employed in places with trough idlers. The entire mechanism of Shiftable cables can get shifted in transverse fashion. High angle belts are on their part suited for slopes reaching angular inclination of up to 80 degrees.

Gearless drives customized for high power requirements are now available. It means that transporting materials with belts has become even more efficient and reliable. These kinds also requiring lower maintenance relative to conventional drive systems.
