It can be executed in dusty environments and is suitable for all types of belts with varying widths and thicknesses. We find this a more economical and durable method. Upper heating platens will be removed. Plugging-in again when temperature drops to 142°C. The steel cords will be cut with a special cutting tool. It should have better joint effect. Periodical Inspection of belt conveyor, belt joints and idlers and other equipment parts and immediate corrective action like repairing of weak joints. STEEL CORD CONVEYOR BELT SPLICING - STEP BY STEP. A vulcanized splice is the process of bonding two belt ends together through the application of Uniform Pressure and Temperature. Vulcanizing the Splice.
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. A pressure of approx. The longitudinal tearing of conveyor belt will not only cause the loss of equipment, but also seriously affect the production progress. 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. Rigid platens are not suitable for worn belting sections because they bridge the low spots. With an increased demand for longevity and protection against unplanned interruptions, REMA TIP TOP splicing materials deliver high quality compounds with uniform gauge, unmatched shelf life and compatibility with most major brands of conveyer belting. 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. The outers are at the inner side executed with a grip surface in order to increase the frictional resistance. As it creates the highest return to original belt strength, it is ideal for splicing, cuts or tears, holes, or breakdowns between steel cords and fabric.
If this additional part would not be applied, the warp cords could shift and could possibly be pulled out. 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. Where gaseous, static or dusty conditions exist, the danger of sparking is eliminated. The longest operation time is required, so that it will reduce maintenance cost and have the shortest possible downtime. REMA TIP TOP splicing kits contain all required materials and solutions for on-site conveyor belt splicing. Precautions for conveyor belt joint vulcanization: - Things should be paid attention to in the vulcanization joint process of the old conveyor belt. The following six chapters clearly demonstrate how to mount and splice steel cord conveyor belts. This angle and radius of the belt fastener results into a maximum allowed specification without loss of strength and a negative effect on the steelcords. The ends are shaped like matching ends of shallow steps.
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. If you are unable to complete the above request please contact us using the below link, providing a screenshot of your experience. Types Of Hot Splicing Repair Material. The knife is held at a 45° angle. Working platform will be removed. The short side bears too much force when the force exceeds the bonding force between the steel cord and the conveyor belt, this cord will be drawn out, and the adjacent cords will be drawn out one after another. The reasonable curing temperature is generally 144℃~147℃. Restricted use of cookies in the browser configuration may affect some functionalities of the website. The curing time should be determined according to the specifications provided by the conveyor belt manufacturer and the corresponding thickness of the conveyor belt. For the steel reinforced bucket elevator belt, with the structure of steel cord carcass with two layers of transverse steel wire reinforcement at the top and bottom cover, we recommend our clients to join the belt ends together with fastener/clip, which is easy to operate and good enough for application in cement and mining industry for the vertical conveying of materials with normal temperature or hot temperature at 100-120 ℃ or 150-180℃. To us, the elevator belt is the key in combination with a highly critical part, the elevator belt fastener.
Cold vulcanizing splicing is fast and high efficiency, but it is only used for the emergency joint of a variety of conveyor belts. There are two types of hot splicing material for conveyor belts, including Uncured Cover Rubber(Top Cover) and Uncured Intermediate Rubber(Tie Gum), they are used to join or repair fabric & steel cord belts by hot vulcanized belt splicing. In order to ensure the normal operation of the conveyor and avoid the long-term production stagnation caused by the fracture and tear of the conveyor belt, we need to install the conveyor belt broken and tear protection and monitoring device. Comparison Chart | | FASTENERS | COLD SPLICE MATERIAL | HOT SPLICE MATERIAL | |-----------------------|----------------------------------------------------|--------------------------------------------------------------------|-----------------------------| | STRENGTH | 50-80% | 80% | 80% | | DOWNTIME | 1 TO 6 HOURS | 4 TO 8 HOURS | 4 TO 8 HOURS | | EXPECTED LIFETIME | Short (25% belt life). Along with knowledge about conveyor belts types, construction, procedure of belt joints. Heavy duty industry demands the utmost performance of components used in elevators. It is suitable for medium and long distance, high load capacity and high speed Widely used in mines, coal yards, chemical industry, metallurgy, construction, ports and other departments.
The joint will be taken out in a short time and damaged. Keep stock of required belt valcanizing material and suggest procurement action. Splicing Kits for Steel Cord Conveyor Belts. Rubber edges are applied on both belt sides, coated with solution and dried well. The function of obtaining information about users and their behavior is carried out by voluntarily entered information in forms and saving cookies in end devices. Why has the vulcanizing method been discarded by many? It is applied like a second core rubber sheet. 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. Belting can be plowed or cleaned more efficiently.
4) Steel cords with original core rubber. The time required to cure will depend on belt thickness and compound: belt manufacturers normally include time and temperature tables in splicing manuals. The cloth should be approx. We process personal data collected when visiting the website. Cold belt joint, that is, using a cold adhesive to carry out the joint. When the conveyor belt is punctured and torn by a sharp tool, the conveyor belt idler changes its position by inserting the sharp tool of the conveyor belt, thus driving the limit switch to make the conveyor statistics. Perform any other duties as may be assigned by the Engineers from time to time. 10 bar (150 psi) is applied with oil pumps. Cooking temperatures range from 120 to 200 degrees Celsius (250 to 400 degrees Fahrenheit), depending on belt type and rubber compound. The presented method is reliable and can be used for a broad range of cord diameters and designs.
During our inspections on many bucket elevators constructed by OEM's, we have studied all the information and have developed our Polysur® Solid belt fastener. The belt centre is marked on both belt ends and also at a minimum of three other points that are approx. Conveyor Belt Jointing Guide method: Cut The rubber belt into a ladder (one step for each layer of canvas). Spliced belt will be lifted and lower heating platens are removed. 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. 3) Core rubber sheets. Hot & cold joint for fabric and steel cord. Vulcanized splices require the cutting away of layers of rubber covers and fabric carcass to let the belt ends be overlapped and joined. Conventional equipment is too expensive. Carry out repairing of belt vulcanizing machines and tools. After curing time has elapsed, platens will be allowed to cool down to 80°C (150°F).
This kind of joint method is more efficient than mechanical joint, and also more economical. The exact location of the wear is the area where the fastener comes in contact with the drive pulley. 5 t / M3 of various bulk, granular, powder and other loose materials, can also be used for conveying adult articles. For all splice designs, it is important that the overlapped areas and any materials added to the joint be properly installed to minimize damage to the finished splice from belt-cleaning systems or other components. The bottom part of the vulcanizer can be used as a working table.
The unique removable rubber wear part that is fitted on the aluminum wedge section of the Polysur® Solid belt fastener prevents the belt from wear and extends durability. The vulcanization is initiated by plugging the heating platens in. This is accomplished by a laminated platen floating on the pressure bag. After several minutes allow temperature to rise to 142°C (290°F). Moreover, this central rubberized section ensures the safe use of different belt constructions with different belt thicknesses. 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. The elevator belt is the heart of the elevator.
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. For high-class splices, an air-conditioned, dust-free assembly hall with a modern vulcanization device, fresh and suitable (unvulcanized) splicing material, and experienced engineers and splicers who carry out the work in accordance with the instructions of the conveyor belt manufacturer, are required. The wedge ensures the guiding and protection of the elevator belt and procures an extra protection surface as well. High-quality Hot splicing repair materials have Long-Shelf life in common storage conditions, up to 24 months, it is suitable for long-distance transportation. 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. The fingers—each typically 30 or 50 millimeters (1-3/16 or 2 inches) wide at the base and between 850 to 1200 millimeters (33 to 48 inches) in length depending on belting specifications—are interlaced, and then the hot vulcanization is preformed. Nylon conveyor belt has the characteristics of thin body, high strength, impact resistance, good trough forming, strong adhesive force between layers, excellent flexibility and long service life. Larger fabric belt splices can be cured in two, three or more settings of the vulcanizing press without problems. Uncured cover rubber is better to be used as a cover rubber replacement material for splicing a conveyor belt. This area is exposed to moisture and the possibility of wear caused by bulk materials entering the joined ends. Use NDT (non-destructive testing) technology for joint quality to ensure joint strength during traction operation; 3.
