Conveyor belts form the backbone of the mining operation, delivering materials and fine from the mines to the mining plant. Conveyors are also used in conjunction with stackers and reclaimers to manage the distribution of mined materials. There are, however, a few different types of conveyor belts. The types of conveyor belts used are dependent on the work required.
PVC Conveyor Belts
PVC conveyor belts, or otherwise known as solid woven conveyor belts, are used in the mining sector to transport aggregates, materials, and fines from the mine (whether open-pit or underground) to the mine plant and/or the stacker system. PVC is used both in underground and above-ground applications and is known for its anti-corrosive properties. PVC is also flexible, putting less strain on the conveyor support. It is resistant to damage, resistant to impact damage and cannot be damaged by oil and bacteria. PVC conveyors are also very easy to install, and there are numerous different kinds of PVC belt weaves with different levels of strength and resistant properties.
Rubber Conveyor Belts
Rubber conveyor belts are used in both the mining as well as industrial applications. As a cheaper alternative to the PVC and nylon weave conveyor belts, rubber conveyor belts still provide the corrosion resistant properties, and flexible support for delivering materials, however, rubber conveyor belts are not as resistant to tearing and impact damage as the solid woven belts.
Wire Reinforced Conveyor Belts
Wire mesh conveyor belts or those wire belt systems are more rigid than the PVC and rubber conveyor belt systems. However, they can be used in a number of applications of which rubber and PVC cannot. This includes any process that involves the application of heat. For this reason, wire belt systems are used in many industrial processes for manufacturing. Heat resistant conveyor belts are mainly made from metal composites with varying levels of limited anti-corrosive properties. Wire-reinforced PVC belts are also constructed for the mining sector whereby they may be less flexible and more difficult to install and manage, but they can perform while carrying incredibly heavy loads.
Food Industry Conveyor Belts
Much like the metal conveyor belts, food industry conveyor belts are mainly made from metal composites. The food industry often requires complex conveyor systems for the various stages of the food production process, so each wire belt system needs to be custom designed for the operation at hand. These belt systems also require heat resistant properties, but they also have to be treated in such a way that will not result in food contamination.
