Conveyor Pulley


Belt conveyor pulley is one of the most versatile components in conveyor systems, used to change the direction of the belt in the conveyor system or to drive the belt or to put tension on the belt. Belt conveyor pulley manufactured by RPIC cover all the basic functions required for the operation of the system, as it includes head pulley, drive pulley, motor drum, bend pulleys, take up pulley, snub pulley and tail pulley, which are specially designed conveyor layouts according to their role and position in the belt. The lagged pulley can be head pulley, tail pulley, take-up pulley, bend pulley, etc. We provide rubber and ceramic lagged pulleys.
RPIC Conveyor Pulleys are widely used in sand quarries, coal mines, metallurgy, machinery, ports, construction, electricity, chemistry, food packing and other industries.

Product Introduction

   The drum is the main component that transmits power. It is divided into three types according to their load-carrying capacity: light, medium and heavy.

Light: Bearing aperture 80-100mm, the shaft and hub are single-width plate welded cylinder structure connected by single key.

Medium: Bearing aperture 120-180mm, the shaft and hub are expansion sleeve connection.

Heavy: Bearing aperture 200-220mm, the shaft and hub are expansion sleeve connection, and the drum body is cast-welded structure.

Product Description

    Conveyor pulley stays at two ends of belt machine. The pulley can be divided into two categories: Driving pulley and averting pulley, driving pulley is the main part for transmitting the power and there are two kinds of pulley sets: Smooth surface and rubber surface, and rubber surface can be classified into smooth rubber surface, herringbone rubber surface and diamond rubber surface to meet different technical requirements. Averting pulley can be classified into smooth rubber surface and smooth steel surface.

    The products are widely used in coal mines, metallurgy, machinery, ports, construction, electricity, chemistry, food packing and other industries

     D250-D1800mm, or according to customers' requirement. 

     With belt 500mm-2200mm, or according to customers' requirement.
