Conveyor for material extracted from mines or quarries

摘要

The conveyor belt has two opposing profiles (3) with their transverse section in the form of capital 'sigma' and welded at their median part (4) to a metal sheet (5) that forms the width of the conveyor. The median part of the profile extends further than the two outer edges of the profile (3), allowing welding of the sheet to the profiles by a high energy source such as a laser beam or electron bombardment. A second metal sheet (8) is welded to one of the outer edges (3) of the profile to close the conveyor. Welding is again carried out by a high energy source such as a laser beam or electron bombardment. A traction chain is welded to the first plate.
