Aug 18, 2014 2.SNUB PULLEY Mounted close to the drive pulley on the return side of the belt, the snub pulleys primary job is to increase the angle of wrap around the drive pulley, thereby increasing traction. Its secondary purpose is reducing belt tension, which is important in maximizing conveyor component life. May be lagged for longer wear life.
Snub pulleys can therefore optimise the cost of your conveying system, since they reduce the belt tension which means that a conveyor belt with a lower belt strength can be used for the same purpose. When using conveyor belts with a textured surface, Ambelt recommends the use of pulley lagging.
The secondary position is the area from just before the point where the belt leaves contact with the head pulley to just before the belt contacts the snub pulley. This mounting position, still within the discharge point or over a dribble chute, causes the remaining carryback to
Snub pulleys. A snub pulley improves the traction of the drive pulley, by increasing its belt wrap angle. Drive pulleys. Drive pulleys, which can also be the head pulley, are driven by a motor and power transmission unit to propel the belt and material to the discharge. Bend pulleys. A bend pulley is used for changing the direction of the belt.
Mar 11, 2013 A low tension pulley would be a snub or bend pulley with 50 rated belt tension. You have to then look at the vector force on a pulley to rate its shaft and shell and bearings. If the belt tension is Tmax, and the head pulley has a belt wrap of 180 degrees, then the pulley force is 2 x Tmax, or Tmaxpillow block.
The tension pulley has an arrow on it to indicate the direction of rotation. Install the tension pulley so that the arrow is pointing clockwise when looking at the outer side of the derailleur. If you hear abnormal noise as a result of looseness in a pulley, you should replace the pulley.

Guiding pulleys, also called control pulleys, are adjustable snub pulleys. Guiding pulleys are usually cylindrical. Observe the minimum diameter for counterflections according to the indication in the product data sheets. To achieve good tracking, the arc of contact at the guiding pulley
Similar to the head pulley, this can be mounted in external bearings. It can also have internal bearings. On short conveyors, the tail pulley often serves as the takeup pulley, providing tension on the belt. Snub Pulleys. This type of conveyor belt pulley is located close to the drive pulley.
3. Snub Pulley A conveyor pulley used to increase belt wrap around a drive pulley, typically for the purpose of improving traction. 4. Take-Up Pulley A conveyor pulley used to remove slack and provide tension to a conveyor belt, they are more common to conveyors of longer length. 5. Bend Pulley
The use of a Snub Pulley is to prevent belt slippage which means costly downtime. Mounted close to the drive pulley on the return side of the belt, the Snub Pulleys primary job is to increase the angle of wrap around the drive pulley, thereby increasing traction. Another function of Snub pulley is to reduce belt tension, which is important ...
4.2 - Dimension of pulleys According to the position that they occupy in a belt conveyor, the pulleys must withstand the forces imposed by both belt tension and conveyed load. To be as efficient as possible both for replace-ment and for new installation, proper selec-tion of pulleys

Conforms to IS 8531-1986. Each Pulley is designed according to position in conveyor, considering all tension parameters. Pulleys are statically balanced. All components are standardised and compatible, hence less cost. Rubber Ceramic Lagging. Drive pulley lagging is usually provided to increase traction between belt and pulley.
Likewise, the snub following the head pulley should not be required as a training means, since it is relatively ineffective in its position following the strong head pulley influence. The take-up carriage has a strong influence on the running of the belt at that point, and due to its movement as belt length changes, is subject to misalignment.
Pulley Lagging Services. Pulley Lagging for all styles and types of head, tail, snub, bends, take-ups and drives. Pulley lagging increases the traction between the belt and the pulley, which in turn reduces load and wear on the drive, belt, pulleys, bearings and take-up. Lagged in shop or in place on system.
May 30, 2017 transfer the motion from the drive pulley to the belt. In other words, the belt must maintain a grip on the drive pulley in order for the belt to be set in motion.
