As a seasoned supplier of High Angle Conveyor Belts, I've witnessed firsthand the critical role these belts play in various industries. High angle conveyor belts are designed to transport materials at steep angles, which is essential in applications where space is limited or where a vertical lift is required. The choice of materials for these belts is crucial as it directly impacts the belt's performance, durability, and suitability for different environments and materials being conveyed. In this blog, we'll explore the commonly used materials in making high angle conveyor belts.
Rubber
Rubber is one of the most widely used materials in high angle conveyor belts. It offers a range of properties that make it ideal for this application. One of the key advantages of rubber is its excellent flexibility. This allows the belt to conform to the pulleys and idlers in the conveyor system, ensuring smooth operation. Rubber also has good traction, which is essential for conveying materials at high angles. It can prevent the materials from slipping back down the belt, even when the incline is steep.
There are different types of rubber used in conveyor belts, each with its own characteristics. Natural rubber is known for its high elasticity and good abrasion resistance. It can withstand a wide range of temperatures and is suitable for conveying a variety of materials, including dry bulk solids and some wet materials. Synthetic rubbers, such as styrene - butadiene rubber (SBR), nitrile rubber (NBR), and ethylene - propylene - diene monomer (EPDM), are also commonly used. SBR is often used in combination with natural rubber to improve the belt's abrasion resistance and reduce costs. NBR has excellent oil and chemical resistance, making it suitable for applications where the belt may come into contact with oils or chemicals. EPDM is resistant to weathering, ozone, and high temperatures, making it a good choice for outdoor applications or in environments where the belt is exposed to high - temperature conditions.
Polyurethane
Polyurethane is another material that is increasingly being used in high angle conveyor belts. It offers several advantages over rubber. Polyurethane has extremely high abrasion resistance, which means it can last longer in applications where the belt is subject to heavy wear, such as in the mining or quarrying industries. It also has good cut and tear resistance, which helps to prevent damage to the belt during operation.
In addition to its mechanical properties, polyurethane is also resistant to many chemicals and oils. This makes it suitable for use in industries where the belt may be exposed to harsh chemical environments, such as the chemical processing industry. Polyurethane belts can also be designed to have a smooth surface, which is beneficial for conveying certain types of materials, such as food products, as it reduces the risk of contamination.
PVC (Polyvinyl Chloride)
PVC is a popular material for high angle conveyor belts, especially in applications where cost - effectiveness is a major consideration. PVC belts are relatively inexpensive to manufacture, making them an attractive option for many industries. They also have good chemical resistance and can be used in applications where the belt may come into contact with mild chemicals or solvents.
PVC belts are lightweight, which makes them easy to handle and install. They also have a relatively low coefficient of friction, which can be an advantage in some applications where a smooth flow of materials is required. However, PVC belts may not be suitable for high - temperature applications as they can start to soften and deform at relatively low temperatures.
Fabric Reinforcements
In addition to the outer cover materials like rubber, polyurethane, and PVC, high angle conveyor belts often contain fabric reinforcements. These reinforcements provide the belt with strength and stability. Common fabric materials used for reinforcement include polyester, nylon, and aramid.
Polyester is a widely used fabric reinforcement due to its high tensile strength and good dimensional stability. It can withstand high loads and is resistant to stretching, which helps to maintain the belt's shape and performance over time. Nylon is known for its high abrasion resistance and flexibility. It can provide additional strength to the belt and is often used in combination with polyester for enhanced performance. Aramid fibers, such as Kevlar, are extremely strong and lightweight. They offer high - strength reinforcement and are suitable for applications where the belt needs to withstand very high loads or where a high degree of cut and tear resistance is required.
Sidewall and Cleat Materials
High angle conveyor belts typically have sidewalls and cleats to prevent the materials from spilling off the belt. These sidewalls and cleats are usually made from rubber or polyurethane. Rubber sidewalls and cleats offer good flexibility and adhesion to the belt surface. They can be easily molded into different shapes and sizes to meet the specific requirements of the application.
Polyurethane sidewalls and cleats, on the other hand, offer higher abrasion and cut resistance compared to rubber. They can withstand more severe operating conditions and are often used in applications where the belt is subject to heavy wear, such as in the mining industry.
Applications and Material Selection
The selection of materials for high angle conveyor belts depends on the specific application. For example, in the food industry, belts made from FDA - compliant materials such as PVC or certain types of rubber and polyurethane are required to ensure food safety. In the mining and quarrying industries, belts with high abrasion and cut resistance, such as those made with polyurethane or belts reinforced with aramid fibers, are preferred.
In the construction industry, where a variety of materials including sand, gravel, and cement need to be conveyed, rubber belts with good traction and durability are commonly used. The choice of sidewall and cleat materials also depends on the type of materials being conveyed and the angle of inclination. For steeper inclines, more robust sidewalls and cleats are required to prevent material spillage.
