Conveyor Belts Information

Economical; Low friction conveying side; Temperature variation resistantConveyor belts are a continuous loop of material that are driven by a system of pulleys or drives to carry goods. They are used in a variety of material handing applications, including food and beverage processing, manufacturing, mining, packaging, and power transmission. Some conveyor belts are designed to transport commercial goods, construction materials, forest products, or pulp and paper. Others are designed for agricultural, general-purpose, or inclined conveying applications.

Elevator belts are designed for vertical applications and have attachments such as buckets or trays. High-temperature conveyor belts are made of materials that are suitable for use at high ambient temperatures, or that are designed to handle high-temperature materials. Often, these products are used in oven conveyor belting and the conveyance of heat-treated parts.

Specifications

Belt material is the most important consideration when selecting conveyor belts. Choices include:

  • Aramid fibers
  • Cotton or canvas
  • Ethylene diene propylene monomer (EPDM)
  • Leather
  • Rubber or synthetic rubber (neoprene)
  • Nitrile
  • Nylon
  • Polyester/polyurethane (PU)/Urethane
  • Polyvinyl chloride (PVC)
  • Silicone
  • Steel and stainless steel
  • Tape
  • Wire mesh
  • Proprietary materials

Dimensions are specified in English units such as inches or yards, or metric units such as meters and centimeters.

  • Belt thickness
  • Belt width
  • Belt length

Additional specifications include:

  • Working load per inch width
  • Maximum operating speed
  • Minimum pulley size
  • Operating temperature

Features

  • Food-grade conveyor belts comply with requirements from the Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA)
  • Modular conveyor belts allow quick replacement of damaged belt sections.
  • Anti-static conveyor belts are used where electrical resistance is important, such as electronics manufacturing.
  • Perforations or tracking features are designed to engage with the pulley to prevent slippage.
  • Top cleats or ribs may be used in inclined conveying applications, and to transport granular materials and powders.
  • Open-ended conveyor belts are sold by the roll and may be cut

Standards

Multiple standards apply to different qualities of conveyor belts, from material of construction to specific applications. Following are links to representative standards.
