The straightness of the splice is doublechecked. We process personal data collected when visiting the website. Oil pumps will be connected to upper traverses. This allows your maintenance personnel the time needed to correct the situation, preventing production loss, belt loss and the added maintenance cost of either replacing or repairing the belt. They splices with two uncured rubber to be completely after heating & pressuring by the vulcanizer, a strong belt splice relies on two important factors: the skill of the operator; and the quality of the splicing materials being used. Uncured Intermediate Rubber(Uncured Skim Rubber) is designed to use as an inter-core cord rubber replacement material in splicing steel cord conveyor belts or a tie gum in fabric belts. The belt ends are carefully laid together in proper alignment with the adhesive, and full contact is achieved with hand rollers, pressure rollers, or hammering in a prescribed pattern. Vulcanized splices require the cutting away of layers of rubber covers and fabric carcass to let the belt ends be overlapped and joined. In many cases one have to tighten the steel cords together and after a template has to be put around the cords which are tightened together and a hot epoxy is casted in the template to seal the belt fastener. One marked belt end is placed on top of the other marked belt end. A vulcanized splice is the process of bonding two belt ends together through the application of Uniform Pressure and Temperature. It has been proved by practice that the heat vulcanized joint is the most ideal joint method, which can ensure high joint efficiency At the same time, it is also very stable, the joint life is also very long, easy to grasp.

The exact location of the wear is the area where the fastener comes in contact with the drive pulley. A conveyor belt splice needs to make several times during the entire user life, hot Splicing is the best operation for conveyor belt jointing. In the actual operation, the conveyor steel cord belt breaking protection and monitoring device is mainly installed on the conveyor. Mechanical pressure deflects the frames causing loss of pressure in the center of the vulcanizer. Each third of the instructions is followed by a video of real splicing works for better understanding. The working is based on clamping forces and friction. The only way to deal with this kind of conveyor belt is to increase the overlap length of the joint. Training & Development.

Steel Cord Belt Joint Procedure Note

The belt ends have to be tensioned as much as possible to avoid sag. Muller Beltex determines the appropriate type of the Polysur® Solid belt fastener according to a number of parameters. The joint will be taken out in a short time and damaged. The wedge is manufactured from rubber and is replaceable. This area is exposed to moisture and the possibility of wear caused by bulk materials entering the joined ends. 48–53, BONNERIC M., AUBIN V., DURVILLE D., 2019, Finite element simulation of a steel cable-rubber composite under bending loading: Influence of rubber penetration on the stress distribution in wires, Measurement, Vol. 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. Precautions for conveyor belt joint vulcanization: - Things should be paid attention to in the vulcanization joint process of the old conveyor belt.

They remain completely covered by rubber after this procedure. Pages 13 to 26 are not shown in this preview. Protective Film Color, Sizes, or per roll measurement can be customized. Steel cord belt fasteners produced by other suppliers are often locked (single use only). The belt ends are bend 90° with a radius of 75 mm. 20 mm width is cut out of the upper cover so that the steel cords become visible. In practical applications, the integrity of the splice is critical to minimizing the risk of downtime. At that time, the existing monitoring and protection device could stop the conveyor only when the sharp edge penetrated a certain depth. The prime advantage of a vulcanized splice is that the hot vulcanized splice is nearly as strong as the belt itself, the splice results in longer belt life, and because of that, conveyor belt downtime is reduced. There is no need to build up worn sections when splicing and repairing a worn belt. 300 mm (12 inches) longer in the longitudinal directions. The vulcanization is initiated by plugging the heating platens in. It has high tensile strength and wears resistance. Wears faster than the belt.

The ends are shaped like matching ends of shallow steps. The alignment is checked again. The centre lines on each end must be precisely aligned. Steel cord elevator belts, such as our Polysur® Ferro steel cord elevator belts, are preferably made endless with the matching designed Polysur® Solid belt fastener. Use NDT (non-destructive testing) technology for joint quality to ensure joint strength during traction operation; 3. With steel-cord belts and finger splices, it is important that the press be large enough to cure the splice in a single setup to avoid undesirable rubber flow and cord displacement. Working platform will be removed. What is Vulcanization? Conveyor Belt joint methods are: Mechanical Joints, BELT JOINTING SOLUTIONS – COLD VULCANIZING CEMENT, hot vulcanization joints and other commonly used methods. A splice design that is seeing increasing acceptance, particularly with high-tension fabric belts, is the finger splice. 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. Semi-Permanent (dependent on splice conditions) | Permanent | | METAL DETECTORS | No | Yes | Yes | | MATERIAL SIFT-THROUGH | Yes | No | No | | BELT DAMAGE | Holes, punctures, open cut moisture penetration | No | No | | CONVEYOR DAMAGE | Yes: Idlers, Pulleys and belt cleaners | No | No | | AMBIENT CONDITIONS | No problems | Susceptible to moisture and dirt contamination.

The three parts of the belt fastener are provided with bolt holes. After several minutes allow temperature to rise to 142°C (290°F). When belts 'run-off' due to misalignment or some other unforeseen reason, the odds are that a metal splice will 'hang-up' and pull out, or 'hang-up' and rip a strip off the side of your belt. Install the belt breaking protection monitoring device on the conveyor to reduce the possible accident hazards caused by belt breaking. BAJDA M., BŁAŻEJ R., JURDZIAK L., 2016, A new tool in belts resistance to puncture research, Mining Science.

Bias spices are most common, as the angle increases the length of the bonding surface and reduces stress on the splice as it wraps around the conveyor's pulleys. Vulcanizing the Splice. Carry out repairing of belt vulcanizing machines and tools. What is Hot splicing? Heavy duty industry demands the utmost performance of components used in elevators. General cold bonding joints, hot. All gaps between the cables are carefully filled with intermediate core rubber up to the height of the cables. The curing time should be determined according to the specifications provided by the conveyor belt manufacturer and the corresponding thickness of the conveyor belt. There is a savings in labor since there is no need to shim worn sections. Upper platens are placed and aligned.

These centre points are then joined into a centre line using a chalked string. Belt must be dried | Overhead tarp is sufficient | | SPLICE FAILURE | No Warming | Warning Period | Long Warning Period |. The position and the number of bolt holes can either be calculated by Muller Beltex engineers through a calculation program, knowing exactly how much safety the clamp provides related to the belt strength, or determined by our customers engineers. Belt surface, ramps and edges are being inspected visually. SKE machinery is a service provider of belt bulk conveying system. Every elevator belt will first develop wear and tear in those areas where these foreign objects are attached to the belt, whether the application is hot or cold. Shortest possible downtime.

The solution is to install longitudinal tear monitoring protection device at the loading point. Spliced belt will be lifted and lower heating platens are removed. A pressure of approx.
