Center drives: located between the conveyor ends. A drive placed at the center, or anywhere along the conveyor's length (but not at either end), is commonly referred to as a center drive, intermediate drive, or mid drive. Center drives are installed below the conveyor, directly under the transport media, and are often used when there are ...

Introduction. Pulleys are rotary components, used in belt conveyors, which have the function of transmitting movement, diverting direction or even stretching the belt. This equipment consists of four main structural components: the shaft, the hub, the disc and the cylinder. It is possible to visualize below, in Figure 1, the distribution of ...

A conveyor belt works by using two motorized pulleys that loop over a long stretch of thick, durable material. When motors in the pulleys operate at the same speed and spin in the same direction, the belt moves between the two.

The drive pulley is what moves a conveyor belt. Its surface is covered with chevrons or diamonds to create enough friction between the belt and pulley to move the conveyor belt. They can be single or double sided and have one or two drives. How many drive pulleys a conveyor system has depends on how big the system is. Bend Pulley
