The specifications of a granite conveyor belt can vary depending on the specific application, but here are some common factors and features to consider when selecting a conveyor belt for transporting granite:

  1. Belt Type:
    • PVC/PU Belts: Suitable for light and medium loads; good for indoor environments.
    • Rubber Belts: More durable and suitable for heavy-duty applications in outdoor and harsh conditions.
  2. Width and Length:
    • Belt widths typically range from 300 mm to 2000 mm or more, depending on the volume of granite to be transported.
    • Length is determined by the specific layout of the conveyor system and the distance between loading and unloading points.
  3. Thickness:
    • The thickness of the belt can range from 3 mm to 10 mm or more, depending on the type of granite and load.
  4. Tensile Strength:
    • For granite transport, the conveyor belt should have high tensile strength to handle the weight of the material. A typical range would be 1000 N/mm to 5000 N/mm (Newtons per millimeter).
  5. Surface:
    • Smooth or textured surfaces are chosen based on the required friction for holding the granite material.
    • Chevron belts are often used for inclined transport to prevent sliding.
  6. Temperature Resistance:
    • Granite mining can generate significant heat, so belts may need to be resistant to temperatures ranging from -10°C to 150°C, depending on the environmental conditions.
  7. Material:
    • The conveyor belt’s surface is often made from high-quality rubber with properties like abrasion resistance, impact resistance, and resistance to oils, acids, and weathering.
  8. Skirting and Seals:
    • Proper skirting and seals are required to contain material on the belt and prevent spillage.
  9. Rollers and Pulleys:
    • Heavy-duty rollers and pulleys are used to support the granite load and reduce wear on the belt.
  10. Speed:
  • The conveyor belt speed for granite can vary but is typically between 0.5 to 2 m/s (meters per second) based on the system’s capacity.

These specifications should be customized based on the volume of granite being transported, the conveyor’s environment, and the overall processing capacity.
