Correct selection of conveyor pulleys for the application

Conveyor pulleys can be specially engineered or selected from a pre-engineered range. Steel shells are made from heavy wall pipe, but can suit specific dimensions. Stainless steel is ideal for corrosive conditions.

Solid end disc construction, with minimum rim overhang, prevents accumulation of material. All components are machined to ensure concentricity. A crowned finish is preferred for head or drive pulley application.

The recommended method for shaft-to-end disc fitting is by internal locking elements that provide a demountable keyless high torque connection. The easy release capability permits removal of the shell from the shaft for maintenance. Other shaft connections include compression hub, taper fit, or welded shaft for less critical applications. Each pulley is statically balanced on completion.

Pulleys may be covered with a range of laggings to increase the friction co-efficient or reduce wear on the pulley face. Cold bonded or hot vulcanised rubber can be moulded plain, diamond and herringbone grooved. Ceramic offers the best resistance to wear and very high friction co-efficient.

Self-cleaning pulleys are for adverse conditions, especially where material builds up on the pulley face. Build-up on the pulley is a cause of belt and splice damage. Wing style pulleys can be used for large lumps, sharp and sticky materials. Spiral type pulleys are used for dry, free-flowing materials.

The correct selection of pulleys will optimise conveyor belt life, preventing damage from incorrect belt tracking, and minimising material build-up.
