What is a Pulley on a Conveyor? Agriculture Queensland

A conveyor pulley in a conveyor belt system is one of the most essential parts of any mining machinery. Conveyor pulleys are mechanical devices used to change the direction of a conveyor belt and consists of a head pulley and a tail pulley. Other components of pulleys include end discs, locking elements, bearing assembly, shell and staff. 

H.E.M.E in Central Highlands specialises in conveyor overhaul and fabrication, and we are the experts in conveyor belt systems. Listed below are some of the most common types of pulleys used by professionals. 

Live Shaft Pulley

A Live Shaft Pulley has a shaft fixed to either end, allowing the shaft and body of the pulley to rotate simultaneously. The bearing assembly is installed externally on the end disc. This is the most frequently used pulley in the mining industry and can be customised to suit many conditions.

Dead Shaft Pulley

The bearings are inside the shaft of a Dead Shaft Pulley, only allowing the body to move around the shaft. This eliminates the bending movement that can occur through the locking element, making it more stable.

Gearless Drive Pulley

This pulley is installed with a low-speed synchronous motor directly to the shaft. This allows greater power and flexibility as mining vehicles increase in size and capacity. A gearless drive pulley can reduce power usage and increase efficiency by reducing the need for gearboxes and high-maintenance pieces of equipment. 

Stub Shaft Pulley

With a Stub Shift Pulley, each end disc comes with two separate stubs attached, removing the locking element. This drastically reduces the weight of pulleys in confined and hard-to-reach places. This type of pulley requires a high level of design as they are quite intricate. 

Different types of pulleys are required for different jobs, so many sure to pick the right one. If you need advice on conveyor overhaul and more, call H.E.M.E on 07 4982 3001 or contact us online to get a quote.
