Before the invention of conveyor belts, material handling involved incredible effort, time, and manpower. Today, conveyor belts are a crucial tool in the material handling industry and are most commonly used to transport bulk materials safely and efficiently.
Belt conveyor systems consist of two or more pulleys, also known as drums, with the belt on an endless loop. The drive pulley moves the belt while the idler pulley is unpowered and redirects the belt. Side guide rollers help protect the conveyor belt and prevent premature wear.
Companies that understand the different types of conveyor belts can choose the safest and most efficient system for their needs. We list a few different types of conveyor belts below.
General use conveyor belts
A common type of conveyor belt is solid belts made from rubber or fabrics such as nylon, polyester, nitrile, or neoprene. The right type of belt material depends on your use. For example, rubber conveyor belts are typically used in mining and milling industries, while grocery stores commonly use PVC belts.
Woven metal conveyor belts
Interlinking chains or wiring make up woven metal belts to allow for airflow. This design is made for industries that require drying, cooling, and the heating of food, electronics, glass, and more. Conveyor belt manufacturers can build woven metal belts to the company’s specifications.
Plastic interlocking conveyor belts
Plastic belts are a modular alternative to metal interlocking belts and are ideal for applications that require frequent cleaning and belt replacement. You’ll commonly see plastic belts in food handling, packing processes, or in the automotive industry.
Industries that use filter belts include water treatment companies, breweries, and chemical factories. Filter belts are made of metal or synthetic fibres and drain excess liquid, filter out toxins, and allow particulates to pass through.
Hinged belts feature interlocking hinges that are capable of rotating around the pulley system while offering a flat, solid surface. Hinged conveyor belts are often used for small products and recycling applications.
Whether you need a conveyor system to transport sensitive materials or one that can handle bulk-steel handling, conveyor belt manufacturers like Luff Industries can design and engineer a belt specific to your application.
Conveyor belt idlersLuff’s idlers are built with patented polymer endcaps with triple labyrinth seal. These specialized polymer endcaps surround a maintenance-free bearing that are sealed for life, eliminating contamination from dust and moisture. This saves companies downtime from maintenance and reduces operating costs.
Luff offers the following conveyor belt idlers:
- CEMA B: For light to medium loads and applications
- CEMA C: For medium loads and applications
- CEMA D: For medium to heavy loads and applications
- CEMA E: For tough loads and conditions
- CEMA F: For extreme heavy-duty applications
Conveyor belt pulleysWhat makes Luff’s conveyor belt pulley design superior is the concentricity of 0.0000 – 0.030” compared to the industry standard of 0.080-0.125”. The difference in constant contact with the belt translates to reduced belt wear, less stress on bearings, and less deviation of the shaft. Luff’s belt pulleys are made with heavy schedule pipe and a pulley shell capable of handling more stress. Luff manufactures:
- Drum & wing pulleys
- Spiral drum & wing
- Helix wing pulleys
- Pulley lagging
Impact bedsLuff’s impact beds are designed with a heavy-duty frame that slides apart in two sections. The unique side profile of the impact bars absorb the impact of heavy material and disperses the energy outwards. This prevents premature damage to the belt, reducing maintenance and downtime costs.
- Impact beds and slider beds
- Impact bars made with polyurethane and a UHMW cap to eliminate bold holes
