Return/Tail Pulley A conveyor pulley used for the purpose of redirecting a conveyor belt back to the drive pulley. Tail pulleys can utilize internal bearings or can be mounted in external bearings and are typically located at the end of the conveyor bed. Tail pulleys commonly serve the purpose of a Take-Up pulley on conveyors of shorter

- A conveyor belt must run "True" to avoid damage to the edge of the conveyor belt. RULE 1 The basic and primary rule of tracking a conveyor belt is simply “The belt moves towards that end of the roller it contact first.” The conveyor belt will travel where directed if it has been manufactured, slit and spliced correctly.

6 System components In its simplest form, a belt conveyor consists of a driving pulley (often the head pulley), a tail pulley, the tensioning device, a conveyor belt, and the supporting structure with the belt support (slider bed or carrying rollers).
Pulley, which is provided to increase/decrease, warp/contact angle of belt on nearby pulley, is called Snub Pulley. Take-Up(Tail) Pulley Pulley, which can be moved to keep belt tight, is called take-up Pulley.Take-Up Pulley may be a drive pulley or an idler pulley.

Continental welded steel conveyor pulleys with a.D. hubs and bushings.,-The 3/4" per foot taper of the 0.0. provides a 32 to 1 locking ratio on the shaft.
Also known as self-cleaning pulleys, wing pulleys are primarily used on the tail end of bulk handling systems where loose materials have a tendency to reside on the underside of the conveyor belt, causing damage to one or both components. Wing pulleys incorporate a non-continuous contact surface comprised of individual wings or fins.
Belt Conveyors are also a great option to move products through elevations. Incline Belt Conveyors from low to high and Decline Belt Conveyors from high to low. This manual is short, with quick and easy reading paragraphs, very practical for calculations of belt, chain conveyors and mechanical miscellaneous, in the metric and imperial system.

Check drive pulley, tail pulley, snub roller (if used in drive assembly) and return roller assemblies to ensure these com-ponents are square with unit bed (see ‘Belt Tracking’ section later in handbook for detailed information). The unit must be installed at level elevation across the width to pre-vent erratic belt tracking.

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

#3 Conveyor Belt Tracking Guide BASIC RULES I. The basic, and primary rule of tracking a conveyor belt is simply "THE BELT MOVES TOWARD THAT END OF THE ROLL IT CONTACTS FIRST." II. The conveyor structure must be "TRUE" (relative to center-line) and LEVEL (side to side).
the loaded conveyor at the design velocity of the belt V, in fpm: (1) To determine the effective tension, T e,it is necessary to identify and evaluate each of the individual forces acting on the conveyor belt and contributing to the tension required to drive the belt at the driving pulley. T e
belts are replaced, return idlers and pulleys are replaced and structure is worn through. Material build up on the belt and hardware causes track-ing problems, that will lead to edge damage, that leads to new belt and new idlers. We urge you to use scrapers on the head pulley and plows in front of the tail pulley
Nov 30, 2016· Take up pulley may be a tail pulley or a idler pulley. (d) Bend Pulley : The bend pulley is used for changing the direction of the belt either 180 degree or 90 degree. (e)Tail Pulley : Tail Pulley is provided at the tail end of the conveyor belt. 3. Continuous Weighing Devices. They are used for measuring the load being carried by the conveyor
If conveyor belt slips, check the following according to your belt type and location. Check the slack on the drive pulley for signs of wear or accumulated debris. If a clean belt slips, an increase in belt tension is required. Adjust the belt at the tail pulley (both sides evenly) in
