The function of a take-up is to control the belt tensions at the take-up pulley. The belt loading, thermal growth or reduction, and dynamic tension waves (during starting or stopping) cause variations in belt tensions during conveyor operation. Figure 2 shows a schematic of two simple conveyors. One has a

Snub pulleys are used to increase the winding angle of the conveyor belt to reduce the traction force on the belt. The snub pulley provides a convenient interface to the conveyor belt and provides rotational movement for the speed sensor. With the snub pulley, the return belt can be made flat before entering the tail pulley.

Starting at the tail end of the conveyor, the first standard troughing idler should be located an approximate distance from the centerline of the tail pulley equal to one belt width for 20° troughed idlers, one and one half times belt width for 35 degree troughed idlers and twice the belt width for 45 degree troughed idlers.

The "driver" is usually the most important component of any moving system and it's no different with conveyors. Simply put, conveyor pulleys are responsible for driving the belt. It takes at least two to travel and are categorized as drive or head, return or tail, bend tensioning, snub tensioning or take-up pulleys. Maximum pulley life is ...

How to Choose a Mining Conveyor Belt. There are multiple moving parts and components that help power a conveyor system. Idlers, winches, bearings, couplings, gearboxes, motors, fluid couplings, and scrapers work in unison to transport materials from Point A to Point B. One of the more often overlooked parts of a conveyor setup is none …

Screw Take-up. The screw take-up design utilizes mechanical force to take-up any slack in the belt. This is done by adjusting a threaded tensioning screw integrated into the conveyor frame on each side of the tail …

Conveyor pulleys are commonly used in shipping and marine applications, as well as for industrial equipment and heavy machinery. Systems typically use multiple conveyor pulleys to increase mechanical advantage as it …

The tail pulley is located at the tail end of the conveyor and it turns freely. Now a "belt" can be put around the pulleys. The Drive Pulley turns and moves the belt around (and around, and around). But it is dangerous to have the belt hang down under the conveyor bed. So small rollers are put into the Conveyor Bed to hold up the belt.

Increased Life. The hybrid design of The Eradicator® maximizes both the life of the pulley and the conveyor belt. PCI's self reinforced design discourages wing fold over and prevents incidental damage to the pulley. The Eradicator® also maximizes belt life by reducing deformation commonly associated with high center point designs.

The tail pulley is located at the tail end of the conveyor and it turns freely. Now a "belt" can be put around the pulleys. The Drive Pulley turns and moves the belt around (and …

Tail pulleys are a vital component of a belt conveyor system. This component is subjected to danger whenever any piece of material falls onto the return side of the conveyor belt. Occasionally along its return run, the belt will collect and carry a lump of spilled material to the tail pulley on the non-carrying side of the belt.

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 discharge end of the conveyor, in ...

A conveyor consists of a continuous rubber belt stretched between terminal pulleys. One end is the tail. This is usually where the loading of the cargo takes place, but loading may take place anywhere along the length of the conveyor, and conveyors with multiple …

NOTE — The troughed angle of 15° is applicable for 2-roll belt conveyors only. 4.2.1 For return idlers, the troughing angle of 0°, 10°, or 15°, shall preferably be adopted. 4.3 Flat belt conveyor is that in which the belt runs flat on the carrying side, over an idler or a …

The bend pulleys are called that because the belt bends over them to form a loop for the take up pulley to sit in. Now for our third conveyor, this conveyor is much like the second except for one major change. The drive unit has been taken from the head pulley, and placed after the first bend pulley on the conveyor return.

material from a conveyor system has a significant effect on the environment and is one of the most common problems experienced on many conveyor systems. We address these concerns with a variety of well-thought-out products and solutions. High belt speeds bring additional challenges to conveyor rollers in bearing life, noise and power demands. We

A conveyor belt is susceptible to static electricity as the belt is continuously pulled against the end pulleys. If electrical components are being conveyed, static electricity can be hazardous. Anti-static conveyor belt measures such as conductive belts or static control brushes should be considered to protect products.

Tail Configuration - Different pulley arrangements can be selected for the tail configuration. Drive - Where the drive motor is installed at the tail end. Drive and Snubber - Where the …

equipped with a means to adjust the tension of the conveyor belt. Some tension devices will make this adjustment by increasing or decreasing the distance between the terminal pulleys (i.e., head and tail pulleys in Figure 1) on the conveyor. Other systems will employ additional pulleys along the conveyor

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 is the final summarization of the

All belt conveyors require the use of some form of take up device for the following reasons: 1. To ensure adequate tension of the belt leaving the drive pulley so us to avoid any slippage of the belt. 2. To ensure proper belt tension at the loading and other points along the conveyor. 3. To compensate for changes in belt length due to ...

TAIL PULLEY: 4″ dia., crowned, with 1-3/16″ dia. shaft. END DRIVE: Allows one-direction (unit) operation; add optional center drive for reversible application. TAKE-UP: Screw type unit at tail pulley provides 12″ belt take-up. BEARINGS: All pulley bearings are precision, heavy duty, lubricated, ball bearing units with cast iron housings.

Center drives: located between the conveyor ends. A drive placed at the center, or anywhere along the conveyor's length (but not at either end), is commonly referred to as a center drive, intermediate drive, or mid drive. Center drives are installed below the conveyor, directly under the transport media, and are often used when there …

Pulleys are used on conveyors to support and deflect the belting through the conveyor structure. Pulleys also provide a mechanism whereby the conveyor belt can be trained to run (track) true along the conveyor idlers. The following graphic indicates the location of pulleys on a conveyor. Generally, pulleys are located at the ends of the ...

Helix Wing Pulleys effectively increase the life of conveyor systems by minimizing the need for maintenance and replacement parts. Rejects material – Deflectors discharge material out of harm's ways and pulls it to the sides of the conveyor where it falls away from the pulley and belt contact surface. "Self-cleaning" belt ...

A conveyor belt works by using two motorized pulleys that loop over a long stretch of thick, durable material. When motors in the pulleys operate at the same speed and spin in the same direction, the belt moves between the two. If objects are particularly heavy or bulky — or if the conveyor belt is carrying them for a long distance or ...

Pulleys are crowned with lagging to reduce belt slippage. Return, idler, or tail pulleys redirect the conveyor belt back to the drive pulley, have internal bearings, and are located at the end of the conveyor bed or at both ends of the conveyor with a center drive. The purpose of tail pulleys is to provide tension in the conveyor belt.

The take-up device in a conveyor belt system has three major functions: 1. To establish and maintain a predetermined tension in the belt. ...
