The most critical areas to install training idlers are 30 ft before the tail pulley to ensure proper tracking over the tail pulley and through the load zone. Other important areas are just after the belt leaves the head pulley, before and after the gravity take-up, if present, and lastly a toughing tainer 10 ft before the head pully to ensure the conveyor belt is centred on over the head pulley. Self-training return and troughing idlers should be installed on 100 ft to 200 ft centres, unless the conveyor structure is out of square and then it may be required to install them on 50 ft centres. In the end, belt tracking is essential to a well-running conveyor system. It is far less expensive to fix the problem than to let it drag on year after year, causing additional problems to the conveyor material handling system.
