FlexKing Belts

Conditions at the point of loading have the greatest effect on belt life and performance. The variables which determine the amount of impact on a belt include:
• Material density
• Freefall
• Lump size
• Contact speed
The impact conditions, in conjunction with the speed of the belt determine the:
• Abrasion
• Cutting
• Wear forces
Premium Conveyor Belts
GRT FlexKing® premium conveyor belting is durable and long-lasting. The all-polyester or polyester/nylon carcass with superior adhesion skim compounds can be vulcanized with any GRT cover compound for extra resistance in demanding applications.
• High-quality conveyor belt for a wide variety of service applications.
• Designed for use in hard rock mining, log handling, aggregate, minerals, and other critical applications.
• Manufactured in widths to 72" (1800 mm).
• Tension ratings from 160 PIW to 1200 PIW.
• Available as a made-to-order product using the cover compounds.
Impact and abrasion are equal to freefall in inches: Impact equals the drop in inches from the end of the chute to the belt plus the equivalent freefall inside the chute. If the chute angle is either 30° or 45° from the horizontal, an equivalent chute freefall calculation can be assigned for different belt speeds.
The length of low-angle chutes is not a factor, since friction restricts the speed of the material to a fairly constant level, regardless of length. However, if a chute angle with the horizontal is over 45°, the impact (freefall in inches) equals the vertical distance from the top of the chute to the surface of the belt.
