Mining conveyor belts have changed the material transportation process in heavy industrial operations by making the process more efficient and safe. It occurs by moving excited materials efficiently from one place to another without any human labour within the process and low risk of any kind of accidents.
A Brief History of the Mining Conveyor Belt
Conveyor systems were used in mining and quarrying as long ago as the late 19th century, as coal, minerals and aggregates became more and more in demand. Earlier conveyor belt materials were leather or canvas. People turn it by hand manually. With modernization and the power of the industry these days, the conveyor belts in the mines are developed from time to time.
Functioning
Conveyor belts that you see in mining and quarrying share similarities with those in other industries. They have a continuous loop of durable material, driven by a motor, which moves along pulleys to transport materials.
However, in the mining and quarrying industry, the mining conveyor belts are usually more robust. They can withstand harsh environments and heavy loads.
Components of a Conveyor Belt in Mines
Here is a list of the must-have parts in a conveyor belt:
- Belt: The belt comprises durable materials like rubber or PVC with special reinforcement. This helps it to withstand abrasive materials and resist impacts.
- Pulleys: Heavy-duty pulleys guide and support the belt. It enables smooth movement even under high loads and harsh conditions.
- Drive Mechanism: There are powerful motors that drive the belts, allowing for efficient transportation of heavy materials over long distances and steep inclines.
- Rollers: Sturdy rollers that have bearings provide support to the belt and minimise friction. This ensures smooth operations.
- Tensioning Device: Conveyors in mining and quarrying require robust tensioning systems. This maintains proper tension, preventing belt slippage and ensuring reliable operation.
With that let’s see some of the real-life applications of belt conveyor systems for coal handling.
