(j) Transfer terminals: In a long-centre conveyor, direction of the conveyor is changed in a transfer terminal where materials from one conveyor is transferred into another conveyor. The second conveyor is laid out at certain angle (generally 90°) to the first one. The discharge from first conveyor takes place at a higher point, and materials is directed to the second conveyor situated at a lower height, through properly shaped and sized transfer chute. This transfer is a critical operation. The transfer terminal is enclosed within a structural framework, covered in all sides, called a junction tower.
6.1.5 Aspects of Belt Conveyor Design
The major points in selection and design of a belt conveyor are:
(a) Checking/determining capacity of a conveyor.
(b) Calculating maximum belt tension required to convey the load and selection of belt.
(c) Selection of driving pulley.
(d) Determining motor power.
(e) Selection of idlers and its spacing.
