Tracking, or training, refers to the way in which the belt rides on the rollers. Conveyor belts should always track centrally. Mistracking occurs when the conveyor belt rides unevenly on rollers, favoring one side over the other.
2 Theoretical basis. Since this study involves the impact problem of coal block and scraper conveyor, and impact dynamics is the theory that mainly studies the deformation, motion or destruction law of objects or materials when they are subjected to the action of variable impact load within a short period of time, this paper is based on the …
Belt conveyors, bucket elevators, steep incline conveyors, and reversing shuttle conveyors, can all be used to bring seamless fluidity and automation to your coal handling operation. Additional equipment such as trippers and plows and belt feeders are available for increasing system flexibility.
Conveyor tracking problems can originate from various parts of your system. As soon as your belt starts mistracking, take a look at these potential problems: Conveyor frame: If your conveyor frame is crooked or slanted, it could be misguiding your belt. Check your framework from all angles to ensure the frame is level and square.
