Gapping belt conveyors create an appropriately sized gap between products to ensure that down-stream processes such as the read rate during barcode or photoeye scanning and sortation occurs efficiently and with minimal errors. Operates with most products – small or large boxes. Adjustable gapping – small to large, around 8 inches to 18 inches.

1 Introduction. Conveyor belts are a cost effective method of transporting bulk materials in many industries worldwide. In the mining industry, conveyor belts are critical components of the supply chain, and the ability to estimate belt wear rates is important to ensure that risk of failure and maintenance activities are managed optimally.

Other cases occur when the very cohesive carry-back material from conveyor belts is transferred to chute surfaces. (c) Failure Envelope - Free Flowing Bulk Solids. 4

To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r) . If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm. Typically, a safety factor is used so that the ...
