The belt conveyor is a key piece of equipment for thermal power plants. Belt mistracking causes higher economic costs, lower production efficiency, and more safety accidents. The existing belt correction devices suffer from poor performance and high costs. Therefore, a design method for coal conveying belt correction devices is …
When the belt drifts, the brute force trainers can cause the belt to fold into itself and fold back into the system. This can permanently damage the belt and lead to further mistracking and spillage. Brute force tracking devices treat symptoms rather than root causes of mistracking and often result in belt edge damage.
Our Holdbacks are also used on flat, overland conveyors to prevent the stress problems a loaded belt can suffer at start-up.
