The pitch line of the belt leaves pulley A at point a. In order to contain this point the center plane of pulley B would have to coincide with XX. Similarly, the belt is delivered from b on the under side of pulley B, into the plane Y 1 Y. The result of this action is that the belt works toward the left and tends to leave the pulleys.

A train system was replaced with a chain of belt conveyors. The main conveyors at this project are the tunnel conveyor PC 2 and the overland conveyor PC 3. Tunnel conveyor PC 2. With 16,820 m pulley center distance and 471 m lift this conveyor is still one of the largest conveyors worldwide.

The former is far more common, and the latter not appropriate for timing and standard V-belts unless there is a twist between each pulley so that the pulleys only contact the same belt surface. Nonparallel shafts can be connected if the belt's center line is aligned with the center plane of the pulley.

Launch the conveyor belt in the reverse run, to the tail pulley. The belt must be empty. Check it during three entire revolutions. Re-launch the conveyor in the current direction and wait another three revolutions. Rectify the tension to center of the belt: if you tighten on the left side, the belt must moves to the right (See figures B & C)

5 CONVEYOR PULLEY SELECTION GUIDE Pulley/Core Diameter – The outside diameter of the cylindrical body of a conveyor pulley, without coating. Finish Diameter – The outside diameter of a coated pulley (core diameter + 2 times the coating/wrap thickness). Face Width – The length of a pulley’s cylindrical body.This area is intended to act as the contact surface for the conveyor belt.

Crowned pulleys are designed to assist in tracking belting in conveyor systems. There are several approaches to the design of crowned pulleys, but they all have the same basic design feature, the center of the pulley has a larger diameter than the outer edges of the pulley, thus the “crown.”

common belt conveyor profiles and tensions. For simplification, the text and diagrams in this chapter are principally con-cerned with vertical curves on the carrying run of the belt conveyor. Concave Vertical Curves A conveyor belt is said to pass through a concave vertical curve when the center of curvature lies above the belt. (See Figure 9.1.)
