Fabric Conveyor Belt

A: Fabric Conveyor Belts are named according to different carcass: Nylon Conveyor belt, EP Conveyor belt and Cotton Conveyor belt.
Nylon Conveyor belt: Flexible, high tension, impact resistant, low elongation, available for the materials handling of heavy duty, high speed and medium distance.
EP Conveyor belt: High modulus, low elongation, impact resistant, excellent heat resistant, available for the materials handling of heavy duty, high speed and medium distance.
Cotton Conveyor belt: Available for the materials handling of medium distance. Fabric Conveyor Belts are named according to different cover grade.
Fabric Conveyor Belts are named according to different cover grade:
Conventional Belt: Generally used for small powder, grain and block materials.
Oil Resistant Belt: Generally used for wood, grain transportation.
Acid/Alkali Resistant Belt: Always used in Chemical materials transportation.
Cold Resistant Belt: The belt can work in some cold environment, like Northeast of China, Russia and North European countries.
Abrasion Resistant Belt: Generally used for transport the hard or shaped materials, like iron ore, diamond, copper and other minerals.

A: Nylon: Nylon is highly durable, resistant to high heat, and can withstand heavy impact. It also adheres well to rubber in the case of a hybrid conveyor belt. It is also less prone to mildew than other fabrics.
Polyester: Polyester is another synthetic material used for conveyor belts. It has many of the same benefits as nylon, but is typically less expensive and quieter during operation.
Kevlar: Kevlar is the superstar of heavy-duty conveying. It’s made to withstand flame and substantial impact. It is bulky and made from thicker fibers than most other fabric belts. Some reports say that kevlar belts also run faster and longer than their counterparts.
Natural fabrics: Natural fabrics are woven to be breathable and include cotton and wool.

A: EP conveyor belt has many characteristics such as good elasticity, impact resistance and tear resistance, which can meet the requirements of various complex environments;
The EP conveyor belt has a small fixed load elongation. The use of a small elongation polyester canvas conveyor belt has a fixed load elongation performance that is better than other common specifications of fabric core conveyor belts. It can greatly reduce the running stroke during use and is effective. To reduce the overall equipment cost is extremely advantageous for long-distance material transportation.
The EP conveyor belt has stronger water resistance. When it is used in a humid and cold environment, the adhesion of the rubber’s comprehensive strength will not be affected in any way, it will still work normally, and it will last longer in the service life;
The acid resistance, alkali resistance and heat resistance of EP conveyor belts are excellent. From a long-term perspective, it is more economical to choose ep conveyor belts;
The EP conveyor belt has few layers, thin belt body, light weight, strong plasticity during use, etc. It not only improves the conveying capacity but also reduces the power consumption rate of the equipment, and optimizes the transportation radius. Requirements for reducing energy and increasing efficiency;
The tensile strength of the cover layer of the EP conveyor belt is higher than 15 MPa, the load elongation is higher than 450 %, and the friction loss is lower than 150mm3;
The adhesive strength between the EP strong cloth layers The average value of the longitudinal sample between the cloth layers is greater than or equal to 4.5 N /mm, and the adhesion rate between the covered rubber surface and the cloth layer is greater than 4 N /mm;
The overall longitudinal thickness tear change rate of the EP conveyor belt and the full thickness longitudinal reference force elongation have reached international standards.

A: By their very nature, conveyor belts have a finite life. While it is difficult to define this life, the modes of failure are known. These failures could be classified as gradual failure or sudden failure. Gradual failures mean that the development of a defect takes place slowly; implying that a certain defect or failure development time is involved.
Some factors which govern life of splice are:
Environmental conditions – moisture, humidity, dust, handling (cleanliness) and temperature of the splice area.
Materials – age, shelf life, size of tie gum strips for the splice stage (step), type of solvents, compatibility of covers to bonder material, new to old belt splicing issues.
Mechanical – splice step design, cord spacing for the particular chosen step and cord diameter, splice length, length of butt gaps on the splice, matching belts from different manufacturers, splice curing time, layup quality, splice straightness.
Electromechanical- vulcanize calibration, temperature sensor monitors, platten.
Temperature distribution, pressure control, temperature control.
By understanding the three primary mechanisms of failure, one should be able to identify the factors that maximize belt life. The three primary failure mechanisms for conveyor belts are: Yield, Wear, and Fatigue.
Fatigue is the growth of microscopic cracks in a material caused by repeated loading and unloading. Fatigue failures are often confused with the belt becoming brittle. Most failures are caused by yield, which occurs when a belt is permanently deformed (bent). These failures are usually due to accidents or misuse. Wear occurs as the joints hinge, or the belt rubs against other components. This results in a slight loss of material and weakening of the effected zone.

A: Cord Fabrics
Filaments of Kevlar yarns have only 1.5 denier linear density. The cord constructions use Kevlar yarns as the strength member laid in warp direction, usually with a light weft of nylon or polyester to hold the cords together.
Straight Warp Fabric
In the preferred straight-warp the Kevlar warp cords are place by a series of binder V\ (of nylon) and weft yarns. This ensures that the straight-warp weave has minimum crimp and, hence, obtains 90% of the strength of the fibres in warp direction.
Using a “stacked” or double warp construction the elongation goes maximum 5%. Using straight-warp weaves; it is possible to achieve breaking strength of up to 150 kN/m. This construction offers the cost-saving benefits of a single ply plain woven fabric and, also, provides high transverse impact and penetration resistance, thus eliminating the need for breakers.
Solid Woven Construction
Kevlar fibres have disadvantage of being brittle, and they can be damaged by lateral pressure and friction. This demerit of Kevlar fibre can be overcome by solid woven construction. The solid woven construction causes the Kevlar warp to go through crimp, resulting in a higher elongation break. Because of the heavier construction, belt breaking strengths of up to 4000 kN/m are achievable. These constructions have high impact and tear resistance. Belt joining is achieved with metal fasteners or with standard finger splices. This type of construction is limited to medium or high tension belts
Cabled Cord Construction
The cable cord construction is used in ultra-high tension belting ranging up to 5 400 k N / m breaking strength. Adhesion to rubber is built into the cable of Kevlar, which allows direct replacement of steel cables within the steel belt manufacturing process.
Another advantage with this construction could be gained with splices designed similar to those used with steel cable cord belts. Unfortunately, this type of belt construction has some of the disadvantages of the steel cable reinforced belts, such as being expensive to manufacture and having poor tear resistance along the belt and between the cable reinforcement.

A: Fabric reinforcement:
Our fabric conveyor belts are reinforced by 2-5 rot-resistant plies made of synthetic EP or PP fabric. These fabrics possess a good tensile strength/weight ratio, have excellent flexibility and troughability, low elongation, high impact resistance and good chemical resistance.
Covers:
The carcass of the fabric belts is protected by covers. Cover qualities or grades are characterized by the conveyor belts’ chemical and physical properties. Inclined systems require cleats or fabric conveyor belts with grooved surfaces. Cover thickness depends on the properties of the transported material and on loading conditions.
Skim layers:
Rubber skim layers in the fabric conveyor belt’s carcass provide excellent adhesion between the plies and efficient distribution of tension. They also absorb impact stress caused by dropping material.

A: A fabric belt conveyor, essential in modern industry, efficiently transports goods using a strong, flexible belt made of bonded or stitched layers of synthetic fibers.
The core of a fabric belt conveyor’s design lies in its layered composition. These layers usually include a top cover, a carcass made of fabric layers, and a bottom cover. The carcass, the belt’s primary strength and load-bearing part, is made of multiple layers of fabrics like polyester and nylon, enhancing its strength and durability. The fabric conveyor belt specification often outlines the belt’s dimensions, material composition, tensile strength, and other critical parameters that determine its suitability for various applications.
The choice of fiber in a fabric conveyor belt is crucial to its performance. Polyester and polyamide are the most common fibers used in these belts. Polyester provides high strength, low stretch, and excellent resistance to water and mildew, making it ideal for the warp – the lengthwise yarns in the fabric. Polyamide, known for its high impact and abrasion resistance, is often used in the weft – the crosswise yarns. The combination of these fibers in a fabric belt conveyor ensures a balance of strength, flexibility, and durability, catering to a wide range of industrial applications.

A: Cover Grades
Fabric conveyor belts are available in different resistance types to suit the challenging conditions they might encounter. These include:
Wear-resistant: Essential for belts handling abrasive materials. These belts can withstand constant wear and tear, prolonging their lifespan. Heat-resistant: Designed for transporting materials at high temperatures, such as in foundries or steel mills. These belts can resist degradation at elevated temperatures. Flame-resistant: Crucial for applications in environments where there’s a risk of fire or explosion. These belts are treated to be self-extinguishing.
The specification of resistance types in the fabric conveyor belt specification allows users to select a belt that best fits their operational environment, ensuring safety and longevity of the belt.
Reinforcement Properties
Reinforcement is a key feature of fabric belt conveyors, involving the use of fabrics like polyester, nylon, or a blend of both to provide strength and stability. The reinforcement properties include:
Low Elongation: This ensures that the belt stretches minimally under load, maintaining consistent length and tension in operation.
Good Adhesion to Rubber: The fabric layers effectively bond with the rubber or synthetic cover, providing integral strength and preventing layers from separating under stress.
The reinforcement properties ensure that the belt can withstand the mechanical stresses of load-bearing and motion, while maintaining its structural integrity over time.

A: Resistance: fabrics must be resistant to wear, traction, and tearing to ensure a long lifespan of the transporter.
Dimensional stability: the fabrics used must maintain their dimensions and shape even under mechanical or thermal stress
Chemical resistance: fabrics must be resistant to chemicals used in industrial processes, such as acids, alkalis, and solvents.
Temperature resistance: fabrics must be able to withstand high or low temperatures depending on the application of the conveyor.
Flexibility: fabrics must be flexible to adapt to the shape of the conveyor belt.
Low deformation: fabrics used must resist deformation caused by the weight of the materials being transported.

A: The working principle of the conveyor belt is straightforward: the belt rotates around a series of pulleys, which are powered by an electric motor. The motor drives the pulleys, which in turn move the belt. The belt is supported by idler rollers along its length, which enable it to move along the rollers, providing support for the material being transported.
As the belt moves along its path, it passes over a series of rollers or idlers, that provide support for the belt and allow it to move smoothly. The idler rollers are typically made of steel or other durable materials, and they are spaced apart along the length of the conveyor to provide consistent support.
In order to load or unload materials onto the conveyor belt, a loading chute or discharge chute is typically used. These chutes are designed to guide the material onto the conveyor belt and prevent it from spilling on the ground. For example, in a quarry, a front-end loader may be used to load material onto the conveyor belt, which then transports the material to a processing plant.
Overall, the working principle of a conveyor belt is simple yet effective. By using a continuous belt that is powered by an electric motor and supported by idler rollers, materials can be transported over long distances or along an incline. With their versatility and reliability, conveyor belts have become an essential component of many industries, from mining and quarrying to manufacturing and logistics.
