Belt cleaners can be installed at both the head and tail pulley and serve to ride against the conveyor belt, dislodging any material that may be adhered to the belt. These devices substantially reduce buildup on the belt, and depending on the level of carryback, several options may be appropriate.
Belt and chain tensioners reduce belt or chain slack and transmit drive torque uniformly. They also reduce noise and vibration; decrease sprocket, pulley, belt, and chain wear; and increase the life of drive components.In drives, belts and chains are installed with enough tension to create a level of friction that causes the belts or chains to grip the pulleys and the pulleys to turn.
A conveyor pulley is a mechanical device used to change the direction of the belt in a conveyor system, to drive the belt, and to tension the belt. Modern pulleys are made of rolled shells with flexible end disks and locking assemblies.

A conveyor pulley is a mechanical device used to change the direction of the belt in a conveyor system, to drive the belt, and to tension the belt.. Modern pulleys are made of rolled shells with flexible end disks and locking assemblies. Early pulley engineering was developed by Josef Sitzwohl in Australia in 1948 and later by Helmuth Lange and Walter Schmoltzi in Germany.
A conveyor pulley is a mechanical device similar to a conveyor roller that is used to change the direction of the belt in a conveyor system or to drive the belt or to put tension on the belt. A pulley is much more heavy-duty than a roller and used at either end of a conveyor or near the drive/motor.
6/19/2019· The different components of a belt conveyor system typically are electric drives, pulleys, idlers, and a long belt. A simple conveyor system may look like below: The basics of the Calculations of Conveyor Belt Design Parameters. Belt tension: The belt of the conveyor always experience a tensile load due to the rotation of the electric drive ...

With conveyor aspect ratio (conveyor length to belt width) in excess of about 5 to 1 and in installations with reversing operations, it is advisable to crown both, head pulley and tail pulley. Following this method, a correctly aligned belt can be maintained in its central position as long as there is no excessive deflection of the pulleys.
A conveyor pulley is a mechanical device used to change the direction of the belt in a conveyor system, to drive the belt, and to tension the belt. Modern pulleys are made of rolled shells with flexible end disks and locking assemblies.
Tail pulley Figure 1. Conveyor Belt In addition to being a critical factor in facilitating the movement of the conveyor belt, appropriate belt tension is crucial for other reasons such as preserving the condition of the belt. Too little or too much
A conveyor belt pulley functions at its best when it's customized to the application. MIR specializes in coatings, a vital component of pulley customization. Coatings provide the necessary coefficient of friction between the belt contact surface and the pulley so the system is driven efficiently.
Snub Pulley – A conveyor pulley used to increase belt wrap around a drive pulley, typically for the purpose of improving traction. Take - Up Pulley – A conveyor pulley used to remove slack and provide tension to a conveyor belt. Take-Up pulleys are more common to conveyors of longer lengths.
Belt conveyor used for coal processing industry whose design capacity is 4400TPH and speed of the conveyor will be 4.65m/s. The paper study about design calculations of conveyor, stresses on pulley due to belt tensions at head side, tail/take up and snub side. Above belt conveyor designed according to Indian standards (IS-11592).
Belt tension: A conveyor belt always experiences a tensile load due to rotation of electric drive, weight of the conveyed materials and idlers. Belt tension at steady state can be calculated as: ... where P p is the power to drive pulley (KW), T b is the belt tension (N), and v is the belt speed (m/s).
Tight Side Tension. Total tension to move belt and load horizontally: E 2 = E+E 1. Slack Side Tension. Additional tension required to prevent slippage on drive pulley: E 1 =E x K. Operating Tension. Determines the working strength of the belt to handle the job on per inch of width basis: T= E 2 /W. The Coefficient of Friction
With a pulley lagging system, your pulley and conveyor belt remain in contact at all times. This increases friction and prevents the belt from slipping – which would otherwise rapidly ruin your belt, especially at high rotation speeds. ... Suitable for medium and heavy belt-tension applications, our diamond-profile rubber lagging delivers ...
7/10/2017· In this video we learn how to calculate the belt length as well as the distance between the two pulleys This is common in the HVAC and building services indu...
Second, additional tension must be added to the effective Belt Tension (Te) to prevent slippage on the drive pulley. This is called Slack Side Tension (Ts), or commonly called T2. Ts = D x Te
Table of ContentsPulley Design FeaturesPulley Hub DesignShaftingPulley Lagging In belt conveyor application, a pulley's 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 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.
