Conveyor Belt Maintenance Common Conveyor Belt Problems

Conveyor belts rely on a precise balance of tension to work correctly. If there is too much tension or too little, things begin to go awry, and the belt can slip. Specifically, if the head pulley breaks down or even becomes overly worn, there will no longer be enough tension to keep the belt from slipping around. Get price

High Tension and Low Tension Pulley?

Mar 11, 2013At 50-75% the diameter is 914 mm and so on. Less than 50% of rated belt tension would be 610 mm pulley diameter (snubs etc). See DIN 22101, 22131, Goodyear manuals etc. A tension pulley would be one at rated belt tension (Head pulley, high-tension snub) A low tension pulley would be a snub or bend pulley with 50% rated belt tension.

5 Essential steps to maintain your conveyor belt in

May 21, 2016The tension rollers, if accumulated with excess dirt or the conveyed product, could also cause slight belt tracking. Clean all the rollers using the detergent solution. Inspect the belt tension, adjust it moderately and observe. An overly tightened conveyor belt causes excessive motor draw or breakage under load. Get price

Belt Tech: Conveyor Systems

Slack-side tension-The area of least tension on a conveyor belt; the low-tension areas will vary on the location of the snub and take-up pulleys; they are completely dependent on the individual conveyor and must be identified for each application.

Mining: Considerations in Conveyor Design and Maintenance

Apr 14, 2015For smaller conveyors the simplest take-up system often uses portable hydraulic jacks to tension the belt, and threaded screw rods with lock nuts to then hold the tension. The hydraulic jacks allow the tension to be set accurately. This take-up arrangement is common on bucket wheel excavators, travelling stackers and similar machines. Get price

Ways to maximize conveyor operation

Aug 25, 2017This means we need to understand the operating tension of the belt. There are several sophisticated ways to calculate the operational tension; your chosen belt manufacturer can make these available. By knowing the percentage of the belt's rated tension versus the operational tension, belt performance can be maximized once again. Get price

Comprehensive conveyor maintenance plan reduces tension

Aug 21, 2011Comprehensive conveyor maintenance plan reduces tension Maintenance personnel need to be up-to-date on the latest procedures in order to detect any and all issues in their conveyor. By following simple maintenance procedures, members of the maintenance team can ensure that conveyors will keep product moving for years to come. Get price

Conveyor Pulley, Drive Pulley, Snub Pulley, Take

Head/Drive Pulley is located at the discharge terminus of the conveyor. It provides the driving force for the conveyor. In order to increase pulley life and traction, it often has a larger diameter than other pulleys. Jagruti can supply pulleys with hot vulcanized rubber lagging, plain or grooved, as required by client. Different patterns of Get price
