Conveyor Belt


a component part of a belt conveyor, serving simultaneously to bear freight and to transport it.

The belts are usually rubberized and have either a fabric base or a cable base. Fabric fillers 0.2 to 0.3 mm thick are made of high-strength cotton and of synthetic materials (nylon-6, Dacron, rayon), which handle the stress of traction. The strength of the filler is from 0.5 to 5 kilonewtons (kN), that is, from 50 to 500 kilograms-force (kgf) per 1 cm of its width. The number of fillers in the cross section of one belt varies between three and 12. The fillers are protected against mechanical action and against penetration of moisture by rubber coverings (3 to 10 mm thick on the working side of the belt and 2 mm thick on the other side). Conveyor belts with a fabric base are from 100 to 2,400 mm wide; it is possible to manufacture widths up to 3,600 mm. For significant traction stresses, conveyor belts with rubberized cable base are used; cable diameters are from 2.1 to 11.6 mm, with strength limits from 7 to 60 kN (700 to 6,000 kgf) per cm of belt width. The maximum width of a rubberized-cable belt is 3,300 mm.

Also available are metal belts, either in the form of belts rolled as one solid piece or of wire mesh belts. These are used for transporting hot or abrasive materials. Such belts are made of carbon steel or stainless steel; they are from 0.6 to 1.2 mm thick and usually up to 800 mm wide. If greater width is needed, the sheets are joined longitudinally by welding.
