The structure of a belt conveyor is relatively simple, mainly consisting of a frame, drive rollers, idler rollers, conveyor belt, tensioning devices, drive units, and support rollers. 1. The frame of the belt conveyor is constructed from high-quality steel plates or aluminum profiles, and it is equipped with belt rollers, idler rollers, etc., which are used to drive and support the conveyor belt. 2. The drum that drives the conveyor belt to rotate on a belt conveyor is called the drive drum. The drive drum is powered by an electric motor via a reducer, and it is usually installed at the discharge end in order to increase traction and facilitate pulling. The material is fed in from the feeding end and falls onto the rotating conveyor belt; it is then transported to the discharging end through the friction generated by the conveyor belt. 3. The other type of idler roller on a belt conveyor is the one that is used to change the direction of movement of the conveyor belt; such a roller is called an idler roller for direction change. 4. The conveyor belt is used in belt conveyor systems to carry and transport materials. 5. The function of the belt conveyor tensioning device is to apply a certain amount of pre-tension to the conveyor belt, thereby preventing it from slipping on the drive rollers ； At the same time, control the deflection of the conveyor belt between the idlers to reduce conveying resistance. 6. The function of the belt conveyor drive device is to enable the drive roller to transmit traction to the conveyor belt through friction, thereby moving the belt and transporting goods. 7. The idler rollers of the belt conveyor support the conveyor belt, keeping its sag within specified limits to ensure its smooth operation. 8. The conveyor belt of a belt conveyor is pulled by the friction between the drive roller and the conveyor belt.
