Correct Selection of Conveyor Pulleys for the Application
As application conditions change conveyor pulleys can be engineered and constructed to suit specific applications or selected from a standard pre-engineered range. Steel shells are normally made from heavy wall pipe, but can also be rolled to suit specific dimensions. For corrosive conditions stainless steel is an option.
Solid end disc construction, with minimum rim overhang, prevents accumulation of material. All components are accurately machined to ensure concentricity. Generally crowned finish is preferred for head or drive pulley application.
The recommended method for shaft to end disc fitting is by internal locking elements which provide a demountable keyless high torque connection. The easy release capability permits the removal of the shell from the shaft for maintenance. Other types of shaft connections are available and these include compression hub, taper fit, or welded shaft for the less critical applications. Each pulley is statically balanced on completion.
Pulleys may be covered with a wide range of optional laggings to increase the co-efficient of friction or reduce the wear on the pulley face. Cold bonded or hot vulcanised rubber can be moulded plain, diamond and herringbone grooved. The pattern is selected according to the operating conditions. Ceramic offers the best resistance to wear and very high co-efficient of friction.
Self cleaning Pulleys are an alternative, designed and constructed to perform in adverse conditions, especially where material tends to build up on the pulley face. The principle of both Spiral and Winged pulleys is the inner, self-cleaning tapered cone which discharges material away from the belt.
Build up on a pulley face, is a primary 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.
Correct selection of Pulleys will optimise conveyor belt life, preventing damage from incorrect belt tracking, and minimising material build up.
