The methods of storing and handling conveyor belting and the procedures for tensioning it before making the final splice are just as important as actually making the splice. Protect your conveyor belt investment with proper storage. How to store the conveyor belt?
Belts should always be stored upright in the factory package until used in a cool, dry building and in an area free from sunlight. If possible, store the belt roll suspended on a tube, bar or support stand. Where suspension is not possible, the roll should be stored on a dry surface and rotated 90° every 6 months. Rotation should be performed in the same direction used to wind up the belt. Rotating in the opposite direction could cause the roll to loosen or telescope. It is particularly advisable to rotate a large roll of belting (over 25 tons) to prevent "flat spotting" (cold flow). This flow under pressure creates a thinner belt. Although this condition may correct itself after several months of operation, it is advisable to take steps for its prevention. If the belt is supplied on a steel reel, the belt would be considered as "suspended," and therefore not need rotation. Under no conditions should a roll of belt, especially raw edge or used, be laid flat on its side. Storing the belt flat on the ground, where moisture can penetrate exposed fabric, or storing the belt roll with weight on one edge may stretch the belt. This can cause belt camber or a bowing in the belt, resulting in serious belt mistracking.
This is about belt conveyor installation.
During extended storage, the belt roll should be covered with a tarp or dark plastic. Exposure to sunlight, rain and ozone can have detrimental effects on the rubber covers. The cover should remain in place for the entire storage time.
It is important to make sure the belt is not exposed to extreme temperatures during storage. Ideal temperature for storing a belt is between 40°F (4°C) and 90°F (32°C). Temperatures outside of this range for an extended period of time can have detrimental effects on the rubber compounds.
As the length of time stored increases, and as the size of the roll of belting increases, so does the importance of the following correct storage procedures. Following these procedures will increase the life of the belt once it is installed on the system.
Even if the precautions outlined in this section are followed, it is still possible that the outside wrap of each roll may suffer excessive hardening or cracking during long-term storage. If this situation occurs, remove the outer turn of the roll to assure that optimum cover/carcass quality material is used for splicing.
