Vulcanizing the Splice. The bars are 1-2 mm (1/16 inch) thinner than the belt. STEEL CORD CONVEYOR BELT SPLICING - STEP BY STEP. The joint will be taken out in a short time and damaged. Again, when maintenance is required on one of the pulleys for example, the belt has to be cut and the belt fastener cannot be reused and has to be considered as an unnecessary loss.
The cloth should be approx. 20 mm width is cut out of the upper cover so that the steel cords become visible. About Sai Conveyor ASSOCIATES. The edges are tapped thoroughly with a mallet. Do not tear the cover off! Another anti tearing protection device is composed of a winding hanging idler and a limit switch, which is installed in the idler of the loading point. Mechanical joints, cold-bonded joints and hot-vulcanized joints can be used as needed. Use NDT (non-destructive testing) technology for joint quality to ensure joint strength during traction operation; 3. Steel cord belt joint procedure instructions. The design of the clamp should be so that it supports the belt on the pulley surface and thus prevent wear to the belt. A steel cord splice consists of removing the cover on the two ends to be spliced, stripping the cables, overlapping them and vulcanizing them back together. If the bonding force between the steel cord and the rubber exceeds the breaking strength of the steel cord, the cord with the greatest force will be pulled first, and then the other adjacent cords will be broken or pulled out respectively. The joint area between the two elevator belt ends is the first area where wear will take place. This bias angle is generally 22 degrees; most vulcanizing presses are manufactured with this bias angle built in. For belt constructions ranging up to 2.
Splicing Kits for Steel Cord Conveyor Belts. Nylon conveyor belt is suitable for conveying non-corrosive bulk, granular, powder materials, such as coal, coke, sand, cement and other bulk materials (materials) or finished articles at room temperature, conveying bulk density of 6. The total width of the belt fastener has to be approximately 15 mm less compared to the width of the full elevator belt. So the joint of the centerline of the conveyor belt is very important work when the conveyor belt is connected. If the temperature is too high, the rubber will heat up too quickly, the temperature difference between the inside and outside will be too large, the inner core rubber has not been fully vulcanized, and the outer rubber has begun to age; - If the temperature is too low, the heat up of the rubber will be too slow, the vulcanization will be incomplete, and the joint strength will not meet the requirements. 10 bar (150 psi) is applied with oil pumps. REMA TIP TOP Steel Cord conveyor belt splicing kits and materials have been developed using our extensive knowledge, experience and proven performance in extreme applications worldwide. If this additional part would not be applied, the warp cords could shift and could possibly be pulled out. Conveyor Belt Jointing Guide Instructions _Monster Belting in China. If the pressure is low, the rubber inside the joint will not be tightly bonded with the steel rope and the rubber itself, air and other volatile substances will not be discharged, causing the inside of the joint to look like bread, which affects the quality of the joint. Everything you want to read. Hot, cold and steel cord belts. Keep record of the belt joint condition and action taken. To ensure we keep this website safe, please can you confirm you are a human by ticking the box below.
Belting can be plowed or cleaned more efficiently. Reduces one more maintenance job: the checking and repairing worn out metal splices. The cords should be carefully buffed with a grooved rotary wire brush. The steel wire cord conveyor belt, because of its weak transverse strength between the core and the steel wire, if the steel wire cord is stuck by sharp objects and continues to run in operation, it will cause the longitudinal split of the conveyor belt. End bolts are tightened thoroughly. For positioning of the bottom platen(s) of the curing press both belt ends are folded back. It is applied like a second core rubber sheet. Steel cord belt joint procedure manual. A fabric belt splice consists of two belt ends stepped down and held together by vulcanized rubber.
It must be connected in a endless for practical use, so the belt joint is a very important part of the preparation. Perform routine maintenance of equipment. Steel cord belt joint procedure for concrete. Pages 13 to 26 are not shown in this preview. Mechanical pressure deflects the frames causing loss of pressure in the center of the vulcanizer. Pressure can range from 34 to 1200 kilopascal (5 pounds per square inch to 175 per square inch), depending on the belt.
The centre lines on each end must be precisely aligned. The only way to deal with this kind of conveyor belt is to increase the overlap length of the joint. This is accomplished by a laminated platen floating on the pressure bag. In cold vulcanization, the belt is joined using adhesives of bonding agents that will fuse the ends of the belt together to form a continuous loop. Where gaseous, static or dusty conditions exist, the danger of sparking is eliminated. Splicing Kits for Steel Cord Conveyor Belts | REMA TIP TOP. Cold vulcanizing splicing is fast and high efficiency, but it is only used for the emergency joint of a variety of conveyor belts. Quality of splice material plays a major role in the life of splice, and hence the production is subject to very stringent Quality controls, inspections and testing. In a matter of minutes and ensures Uniform Pressure over the entire platen area.
The cover is cut transversally down to the cables. Our fasteners are designed as light as possible and consist of multiple sections across the belt width, so not one single beam across the full width of the belt. Wears faster than the belt. To get the most out of this page, you may first watch the animation on the left.
The vice-part is the heart of the Polysur® Solid belt fastener. The procedure is repeated for the bottom sides of the belt ends. The joining method for steel reinforced bucket elevator belt. Our Uncured Cover Rubber& Skim rubber are designed for use in step splicing and finger splicing of belts, they are tried and tested successfully domestic.
