GRT FlexKing® Belts

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.

FlexKing® Impact Resistance
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 plus the speed of the belt determine the:
• Abrasion
• Cutting
• Wear forces

  

Impact and abrasion are equal to freefall in inches: Impact = 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. (See Table 4 below).

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 dis-tance from the top of the chute to the surface of the belt.
