What is Conveyor Belt Fastener

Conveyor belt fasteners are manufactured in two styles—hinged and solid plate. Hinged belt fasteners are applied as individual segments to a belt end and then connected with a hinge pin. Solid plate fasteners span opposing belt ends that have been butted together, forming a tight, sift-free splice.

Advantage of Conveyor Belt Fastener

Increased Efficiency
One of the primary advantages of fasteners is that they can help to increase efficiency in a variety of applications. Fasteners can be used to quickly and easily connect two or more components, which can save a significant amount of time and effort when compared to traditional methods such as welding or bolting.
Enhanced Safety
Another advantage of fasteners is that they can enhance safety in a variety of applications. For example, fasteners can be used to secure components in place so that they are less likely to become loose or detached, which could potentially lead to accidents.
Improved Aesthetics
In some applications, fasteners can also improve aesthetics. For example, hidden fasteners can be used to create a cleaner and more streamlined look in furniture or cabinetry.
Greater Strength and Durability
Fasteners are also typically stronger and more durable than traditional methods of joining two or more components. This is due to the fact that fasteners are designed to create a tight connection that is resistant to vibration and other forces that could potentially cause traditional methods, such as welding or bolting, to fail.
Reduced Cost
Fasteners can also help to reduce costs in a variety of applications. This is because fasteners are typically much less expensive than traditional methods such as welding or bolting. Additionally, fasteners often require less labor to install, which can further reduce costs.

How to Select the Proper Belt Fasteners and Reduce Failures

Solid Plate Fasteners
Solid plate are used where a sift-free splice is required (i.e. bulk conveying applications). The ends of the belt prevent fines from sifting through the spliced area, are considered as a permanent attachment, and are seldom used where the belt or the conveyor must be frequently disassembled. Solid plate fasteners also require larger minimum pulley diameters than hinged fasteners.
Hinged Fasteners
Hinged fasteners can be used on systems employing smaller pulley diameters. This design feature allows for a larger range of applications than is available with corresponding solid plate fasteners. Hinged fastener splices can be separated for belt removal or maintenance by removing the hinge pins. Some hinged fasteners have a sift-preventing component and can be used on belts conveying fines.
The hinge pin should be selected as carefully as the fastener itself. Select a pin of the same material as the fastener. (i.e. a stainless steel pin or a stainless steel fastener.)
Solid wire pins are the easiest to insert and are most often used on non-troughing applications. Stranded cable wire pins are recommended for troughing conveyors given their greater flexibility.
Both solid wire pins and stranded cable pins are offered either with or without an external polymer covering. This polymer "jacket" serves as a lubricant when positioned between the loops of the hinged fasteners. As such, this pin style is less likely to wear or corrode. However, they are not the preferred choice where fine abrasive materials are being conveyed, wherein a solid wire or unjacketed cable pin is a better selection.
Other hinge pin choices include nonmetallic pins for smooth running at lower belt operating tensions as well as notched or corrugated pins which reduce the likelihood of pin migration.
Hinge pin selection is as important as proper hinged fastener selection. Properly selected and installed, they contribute to maximum splice life and performance. As with selecting hinged fasteners, the fastener manufacturers should be consulted for hinge pin recommendations.
Light and Heavy Duty Options
Light-duty conveyor belts generally have a tension rating of 160 PIW or less, while heavy-duty conveyor belts have tension ratings exceeding 160 PIW. Light-duty conveyor belt fasteners include wire hooks, common bar lacing, stapled plate fasteners, plastic hinged plate fasteners, and plastic spiral loop fasteners. Heavy-duty conveyor belt fasteners include bolted and riveted plate fasteners and stapled, bolted, and riveted hinge fasteners. Heavy-duty fasteners are available for operating tensions up to 1500 PIW.
Eliminate Belt Fastener Failures
It's also fairly simple to analyze your belt to determine if there is a mechanical lacing that will extend your belt life. A minor tweak such as changing the grade of metal, type of pin, or profile of the lace can dramatically increase belt life on the same material.

Types of Conveyor Belt Fastener

Hinged Fasteners
In hinged-fasteners splices, a strip composed of top and bottom plates joined on one side by metal loops is placed on each of the two belt ends. These strips are attached to the belt by staples, bolts or rivets. The belt is then joined by passing a linking pin through the alternating hinge loops.
Hinged fasteners are usually supplied in continuous strips to fit standard belt widths. These strip assemblies ensure proper spacing and alignment. The strips are fabricated so pieces can be snapped off to fit non-standard belt widths.
The chief advantage of hinged fasteners is that the belt can be separated by removing the linking pin. This way the belt can be shortened, extended, removed from the structure, or opened to allow maintenance on conveyor components.
Hinged fasteners provide several other benefits. Installation on the two belt ends can be done separately and even preformed off-site. While it is not a recommended practice to join belts of different thicknesses – because of problems it can create, including sealing, tracking, and cleaning – hinged loop fasteners would allow different thicknesses of belting to be combined using fasteners matched to their respective belt halves.
Solid-Plate Segments
A second type of mechanical splice is performed with plate fasteners. This class of fastener makes a strong, durable joint with no hinge gap for fines. Plate fasteners are effective in the most rugged conveying applications in mines, quarries, and steel mills. In applications where the belt is thicker than 22 millimeters (7/8-in), plate fasteners are the only choice for mechanical fastening.
Solid-plate segment fasteners are intended for permanent joints only and are not recommended for belts in applications that require opening of the joint to change belt length or location. Solid-plate segment fasteners are typically provided as individual pieces packed loose in a box or bucket. The plate segments are installed from one belt edge to the other using stables, rivets, or bolts.
Bolted solid-plate fasteners have some unique advantages. They can be applied diagonally across the belt to allow use on pulleys that are smaller than the size recommended for the fastener. They can also be installed in a V-shaped pattern, which may be the only choice for using fasteners to join thick, high-tension belts designed for vulcanization.
One problem with bolt-fastened solid-plate segment fasteners is that they typically use only two bolts on each plate, with one on each side of the splice. Tightening down on the end of the splice means the leading and trailing edges are more compressed than the middle of the plate. This allows the middle to crown, creating a wear point in the fastener and in belt cleaners or other systems that contact the belt as it moves on its path through the conveyor.
Riveted solid-plate fasteners are designed for the most demanding, highest-tension applications. The multi-point attachment on each side of the hinge provides the highest holding power of any mechanical fastener. They can be installed without power tools, using a hammer to set the rivets and break off any heads above the belt. This is an advantage in remote or underground locations.
Clipper Wire Hook
Clipper wire fasteners offer one of the cheapest and easiest-to-install fastener options. These wire hooks work similarly to staples and binder rings. Each end of the fastener's hooks fits inside the holes of the belt seams. They clip onto both sides of the opposite belt, looping the two belt ends together. Like hinged fasteners, they provide flexibility to the belt joints. Note that they provide the most benefits to wide belts compatible with lacing similar materials.
Alligator Lacing
Alligator lacing fasteners work similarly to clipper wire hooks, but they provide more structure, less bend flexibility, and a zipper-like fitting. Unlike the other fasteners, they come as one piece that runs along the edge of the belt ends instead of tiny, separate attachments. Installing alligator lacing takes very little effort. The process requires a hammer, and can be done by hand. Alligator lacing works with various belt widths and provides uniform tensioning.

Different Type of Fastener Installation Procedure

Bolt Solid Plate
This kind of conveyor belt fasteners are easy to install on-site using templates, punches and boring tools: first place the template in place. Then, spray lubricant through the template holes and drill or drill holes at both ends of the belt. Insert the bolt into one end of the belt. Fold one end of the belt back and insert the bolt into the other end.
Align the bolt with the template teeth and place the other end of the belt on the bolt. After removing the template, insert the top plate and threaded nuts into the bolts. The woven tape passes through the board and is tightened as you tighten the board (tighten the two outer boards, first keep the tape in place). Tighten the nut; hit the plate with a hammer. Break the ends of the bolts and grind them flat.
Bolt Hinge
Align the template with the end of the belt and nail it into the center arrow away from the belt. Spray holes with silicone lubricant and punch holes in the belt. Place the fastener on the belt with the hinge facing up. Insert the bolt and tighten the nut by hand to engage the lug on the fastener. From the outside to the inside, use a wrench to fully tighten the nut to ensure that the fastening teeth penetrate the bottom surface of the belt. Insert the gauge pin into the fastening ring; unscrew the bolt and grind it flat. Insert the filling tube with the gauge pin as the guide. Once in place, remove the gauge pin. Repeat the above steps on the other end and connect the two ends together. Insert the gauge pins into the two sets of fixing rings. Insert the hinge pin from the opposite end and pour out the gauge pin as you go. Place a washer on the hinge pin and secure it in place.
Rivet Articulation
Use tool to firmly fix the belt, fasteners and guide block in place. Insert up to 8 rivets at a time. The tool aligns belts, hinges and guides to ensure perfect lace.
Alligator Stapler
Align the conveyor belt fastener to the belt, use the alligator preparation tool to lock it in place. Open the staples. The tool inserts two nails at the same time and can then easily move along the belt to drive the next pair.
Scissors Wire Hook
Once the belt are ready for use, guide the belt through the clamp and over the belt support frame, and then lock the belt clamp. Rotate the adjustment head counterclockwise until the roller touches the hook after placing the roller on the hook. Return the lace head to the end of the lace and turn the knob one and a half rotations (counterclockwise). Then, using a drill bit or manual override, drive the broach head across the width of the belt at a low to medium speed. Turn the adjusting knob counterclockwise half a turn, and repeat this operation until the hook is embedded in the belt that is 1/3 to 1/2 of the diameter of the wire. Finally, remove the lace needle, loosen the belt clamp, and remove the belt from the lace.
Alligator Lacing
Install this one-piece fastener strip using only a hammer. The lacing is held tightly in place by clips and a gauge rod as the teeth bite into the belt to complete the splice.
Plastic Rivet and Plastic Spiral Lace
Installations of these non-metallic fasteners should be performed by professionals with extensive training and experience. Accurate Industrial's belt technicians will install these fasteners to ensure the highest possible quality and lace life.

Frequently Asked Questions

Q: How to choose conveyor belt fasteners

A: The characteristics of your belt will determine which buckle you should use. If you need to replace fasteners, please check your conveyor system and pass the following information to Accurate Industrial:
Thickness: Measure the thickness of the belt at the connection location. Don't simply assume that the belt is still at the same thickness, it is when you buy it. The friction with the pulley and the conveying material causes the top and bottom surfaces of the belt to be squeezed and worn, thereby reducing the thickness of the belt. If you want to scrape the belt-remove part of the cover so that the fastener can better grasp the carcass of the belt-remember to deduct the depth of the scraping from the thickness decision. Conveyor belt fasteners suitable for this final thickness are still the final choice of competitors.
Tension and belt ratings: Further limit the area by paying attention to the tension ratings specified by the belt manufacturer. Belts used to carry heavy loads generally require higher tension to overcome friction and resistance to prevent the belt from sagging into the parts of the conveyor. The belt has a tension rating of 160 pounds per inch and can be tied with metal hooks, iron bars, nail plates or plastic hinges. Belts used in heavy-duty applications require stronger hardware connected with bolts or rivets.
Pulley Diameter: Find the pulley 90 degrees or more around it on your conveyor belt and measure its diameter. Wing (self-cleaning) pulley increased by 25%. This number will indicate which lace options are available for you to choose from. Larger pulleys are needed to push larger and heavier solid plate fasteners. Smaller pulleys can only drive lighter fasteners. Hinge fasteners allow the strap to pivot or bend around the pulley. This creates a larger surface area for grip and gives smaller pulleys more traction. But solid plate fasteners are more robust and durable. When the pulleys are large enough to drive them, they are usually the preferred style. Plastic ties can be used in applications where metal fasteners cannot be used, such as metal detection tapes.

Q: What Defects Fastening of Rubber Cloth by Incorrect Fasteners may Bring？

A: In the dynamics of the conveyor belt movement, passing through a transmission drum (shank end) is especially important. The belt is working with bending here and being subject to maximal cargoes, that is why the diameter of a drum is a basic parameter for calculations here. Elastic rubber turns the drum around without any problems, but adding of the fasteners significantly increases the resistance of the repaired part. If fasteners are chosen incorrectly, both the belt and the drum will suffer from an increased waste. When a lock of a too big size is installed, the belt will over slip and the surface of the drum will have some additional impulsive loads. That is why the lower the size of the driving drum is, the lower the sizes of the locks should be.

Q: How Conveyor Belt Fastening is Performed

A: The technology is well-prepared, you will not have to stop the production process for a long time or dismantle the conveyor.
The damaged part is marked and cut in a strict perpendicular manner across the cloth
The first step is marked and cut on the cloth until the necessary cord is reached ( it is required to do it to preserve a smooth surface of the belt). Depending on the width of the belt and loading of such steps, it is necessary to make up to three of them from both sides
After putting one end on the other we receive the same width of the repaired part as the main belt has.
Drill the required number of holes and a fastener is put into each of them (from above and in the lower part), tightening them with a belt fastener bolt
Elastic rubber makes it possible to place the washers at the same level with the belt that will include the drum waste. Some extra threads from the lower part of the belt are eliminated by the breaker, and the repairs are over.

Q: What is the name of belt fastener?

A: In heavy-duty applications like coal, cement, mining, and aggregate, there are two main belt fastener types: Hinged Plate and Solid Plate. These fasteners are installed into the belt using bolts, rivets, or staples (depending on belt type and application).

Q: What are the different types of belt splicing?

A: Here's an overview of the three most frequently utilized and effective belt splices – finger splicing, skive splicing, and clipper splicing.

Q: What is the process of belt splicing?

A: preparation of belt ends, marking and cutting the steps, removal of excess material, grinding the steps, centring and attaching the belt ends, adding fresh material for splicing, inserting the splice into the press and curing the splice. Special equipment (press, special splicing tool etc.)

Q: What is belt splicing length?

A: The overall splice length will be given by L = X + [S. (n-1)] Where n is defined, as the number of plies and s is the step length. All splices shall be made by stripping back the plies at the two ends of the belt in the required manner.

Q: Is belt splicing a trade?

A: Fenner Dunlop's Belt Splicing Traineeship has become trade recognised in Western Australia. This recognition means that now we offer our employees a learning pathway that combines a national certification and trade papers through our Enterprise Registered Training Organisation (RTO).

Q: How do mechanical conveyor belt fasteners work?

A: Mechanical fasteners use a combination of plates and bolts to create a strong, flexible joint. These fasteners are designed to withstand the stress and tension of the conveyor system.

Q: When should conveyor belt fasteners be used instead of vulcanization?

A: Conveyor belt fasteners are preferred when frequent belt replacement or repairs are needed, as they offer a quicker and more cost-effective solution compared to vulcanized splicing.

Q: What materials are conveyor belt fasteners made from?

A: Conveyor belt fasteners are commonly made from materials such as steel, stainless steel, and other durable alloys to ensure strength and longevity.

Q: Can conveyor belt fasteners be used for different belt types and sizes?

A: Yes, many conveyor belt fasteners are designed to be versatile and can be used with various belt materials, thicknesses, and sizes, making them adaptable to different conveyor systems.

Q: How are conveyor belt fasteners installed?

A: Installation methods may vary depending on the type of fastener. Generally, they involve aligning the belt ends, inserting the fasteners, and securing them in place using nuts or other locking mechanisms.

Q: Are conveyor belt fasteners reusable?

A: Some mechanical fasteners are designed to be reusable, allowing for easier belt maintenance and replacement. However, it's essential to follow manufacturer guidelines for reuse.

Q: What maintenance is required for conveyor belt fasteners?

A: Regular inspection for wear, damage, or loose components is crucial for maintaining the integrity of conveyor belt fasteners. Prompt replacement of any damaged parts is recommended to prevent downtime and ensure safe operation.
