TAKE-UP LOCATION This is the take-up location as a percentage of the horizontal centers of the conveyor. The 0% location is at the head and the 100% location is at the tail. This will normally be 100% for a fixed take-up head drive conveyor profile. The program defaults to the conveyor midpoint for gravity take-up profiles.
The required take-up length is calculated as follows, where . S Sp take-up length (m) L conveyor length (m) belt elongation, elastic and permanent (%) As a rough guideline, use 1,5 % elongation for textile belts. and 0,2 % for steel cord belts. Note For long-distance conveyors, dynamic start-up calculations
With gravity-operated take-up systems the tensioning weight must generate the force F 2 in order to achieve satisfactory grip by the belt on the drive drum (spring-loaded, pneumatic and hydraulic take-up devices operate in similar fashion). The tensioning weight must be capable of moving freely. The take-up unit can only be installed after the ...

Since one horsepower (HP) 33,000 ft-lbs/min, required conveyor drive power may be expressed in HP as follows, (Te in lbs) x (V in fpm)/ ( (33,000 ft-lbs/min)/HP) HP. After calculating Te, it is important to calculate T2 slip (slack side tension required to resist slippage of the belt on the pulley.)

PPIs Conveyor Design Program is a web based application for conveyor horsepower calculation, selection of pulleys and idlers, and selection of take-up travel length for fixed take-up conveyors up to 1,000 feet long using our Stretch-Rite calculations. Its use is limited to non-regenerative conveyors that dont exceed 2,000 feet in length and fabric belts with ratings that
Oct 17, 2010 Counterweight calculation. Hi There, I am trying to calculate the take up weight for one conveyor. As I understand, I should check two criterias against sizing the take up. 1- Minimum tension in order to build the determined sag in belt conveyor between idlers. 2- Minimum tension required in slack side T2 of the drive in order to prevent the ...

Aug 04, 2020 Belt length ( (D L D S) * / 2) (2 * L) (D L - D S) 2 / (4 * L) where D L is the diameter of the large pulley D S is the diameter of the smaller pulley and. L is the distance between the pulley axles. You can find the belt length calculated with this equation by clicking on the Advanced mode button.
Jul 07, 2020 Gravity take-up units are used in this study. Conveyor belts rely on the friction between the bottom covering rubber surface and the driving rollers, and the tension device provides a contact force for the conveyor and the rollers, which enables the conveyor belt to obtain a large friction force and avoid slippage with the rollers.
1. Fixed take up device that may be adjusted periodically by manual operation. 2. Automatic take up device (constant load type) Manual Screw Take Up The most commonly used manual take up is the screw take up. In a screw take up system the take up pulley rotates in two bearing blocks which may slide on stationery guide ways with the help of two ...
The math is not as difficult as it appears. Heres the logic behind the center-to-center distance formula 2C Multiplying the center-to-center distance by 2 accounts for the belt length on the top and bottom of the pulleys Note The pitch created by differing pulley diameters is addressed later in the equation. (Dd 2) This accounts for the belt length wrapped around the outer ...

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.

The wrap factor can be as small as 0.08 for dual drive systems with rubber-lagged drive pulleys, an automatic take-up, and 420 of wrap angle, or as large as 1.2 for a single drive system, an unlagged pulley, manual take-up and 180 of belt wrap. Next it is important to calculate T2 sag (slack side tension required to prevent belt sag.) Sag ...
weighted (or gravity type) takeups to be used on commercial belt- -conveyor scale systems. Of the various methods listed, gravity take-ups are arguably one of the simplest and most commonly used means for automatically controlling tension in belt-conveyor scale systems, particularly on larger systems.
types of cord enable rubber to fully penetrate to the center core. If rubber doesnt penetrate to the core, the cord may corrode from small cuts or at the belt ends. STRENGTH DESIGNATIONS As a general rule, current fabrics in use are designated by the working tension or strength of the fabric, shown in pounds per inch of width
