Belt conveyor pulley is a mechanical device which can guides the belt running, changes the belt direction and tensions the belt etc.They are dimensioned according to the characteristics of each conveyor and the position they occupy in a belt conveyor, the pulleys must withstand the forces imposed by both belt tension and conveyed load.
As the belt is the more expensive component, the pulley selection should be adjusted to accommodate the belt.Using the appropriate sized pulley will allow the belt to operate at its full tension rating without placing undue stress and compression on the inner plies.Minimum pulley diameters for conveyor systems are calculated for various belt.

Table of contentspulley design featurespulley hub designshaftingpulley lagging in belt conveyor application, a pulleys purpose is primarily three-fold, 1 support the belt in directional changes, as designed in the conveyor, 2 transmit driving power to the belt, and 3 guide or train the belt.The drive pulley imparts the driving force to the belt and may be located at the head or.
The tension in a conveyor belt decreases as the belt travels around the drive pulley, causing the belt to contract.In order to prevent slip, the lagging must deform circumferentially to match the belt contraction.The belt traction force causes this lagging deformation but, if beyond the limit friction, will allow slip.As the belt contracts it.
The pulley must withstand the forces imposed by both belt tension and conveyed load.A proper selection of pulley enables conveyor belt to be as efficient as possible and easy for replacement or new installation.The selection of pulleys requires few data to determine the construction characteristics and dimensions of pulley.
Belt conveyor pulley series product description damon industry has launched belt pulley series products which are specialized for the belt conveyors, by high strength welding and precise processing, dedicate to provide you the high strength and high quality belt pulley.
You dont need to fill-in all fields or to do the selection step by step.The selecalc engineering programs are a unique family of belt selection aids and calculation programs created by the habasit application engineer team.Selecalc offers evaluation of application cases, selection of best fit of belt and supports conveyor design.
Conveyor pulley selection guide.Snub pulley a conveyor pulley used to increase belt wrap around a drive pulley typically for the purpose of improving traction takeup pulley a conveyor pulley used to remove slack and provide tension to a conveyor belt takeup pulleys are more common to conveyors of longer lengths.Get details conveyor handbook.
Determine the face length of the conveyor pulley the face length of a conveyor pulley is a derivative of the conveyor belt width.In bulk-handling applications, an adequate pulley face length is one that is 2 or 3 inches greater overall or 1 to 1.5 inches greater on each end than the overall width of the conveyor belt.
Conveyor belt drive selection.The ideal location for the drive of a belt conveyor is the place which minimizes belt tensions both during the acceleration and running periods although circumstances may dictate that a drive be located somewhere between the ends of a conveyor locating it at the head end when the conveyor has to be powered to drive it is preferred.

The ultimate strength of the belt in kilonewtons per metre width is shown along with the number of plies.Pn10004 designates a belt with four plies of polyester warp, nylon weft fabric and an ultimate full-belt tensile strength of 1000knm.Alternatively the belt can be often described as 4.
Conveyor and pulley parts.Head pulleys the head pulley is located at the discharge point of the conveyor it usually drives the conveyor and often has a larger diameter than other pulleys for better traction the head pulley is usually lagged with either rubber or ceramic lagging material tail and wing pulleys the tail pulley is located at the loading end of the belt.

With a standard conveyor belt, the belt tension increases steadily from the tail up to the head station and then decreases very quickly during the run over the drive pulley.On the test stands, the increasing belt tension is achieved by slowly moving the pulleys apart.
