Coal Handling Pump Problems. Two key factors cause problems when handling coal. First, coal sinks in water. Second, water collects in low spots. Combine this with a conveyor system, which operates below ground and has dust, fine particles and chunks falling from the belt. With nowhere to drain, water collects, and whatever is with it …

A conveyor belt at a coal mine became loose, ran askew and material was adhering to the corrective roller. This misalignment caused the belt edges to wear, reduced the life of the belt and increased spillage along the conveyor. These problems not only impacted the material handling efficiency but also increased the labor intensity, and created ...

The first is by collecting the cross section from the falling coal stream at a transfer point between two conveyors. This is known as Cross-Stream Sampling. The second method is by collecting the primary increment by sweeping the cross section from the material on a single conveyor belt. This is known as Cross-Belt Sampling.
