The head pulley is located at the point that the conveyor offloads, known as the unloading end of the belt conveyor. Because it drives the entire system, it usually requires a rough coat covering the outer surface to increase the traction of its belt. The head pulley usually has the largest diameter of all the pulleys. Sometimes, a system can have more than one pulley as a drive pulley. The discharging end pulley, usually the largest diameter of the driving roller, is called the head pulley. This is located at the loading end of the belt conveyor. Sometimes it comes with a wing shape to clean the belt by letting material fall aside to the support parts. In a simple belt conveyor setup, the tail pulley will be mounted on a usually slotted rail to allow belt tensioning. In other belt conveying systems as we shall see, tensioning of the belt is left to another roller called the take-up roller.
