When the exact weight of the belt is not known, use average estimated belt weight (see Table 6-1) W m =weight of material, lbs per foot of belt length: Three multiplying factors, K t, K x, and K y, are used in calculations of three of the components of the effective belt tension, T


This article presents a conveyor belt fire classification model that allows for the determination of the most effective firefighting strategy. In addition, the effect of belt design parameters on the fire classification was determined. A methodology that involves the use of numerical simulations and artificial neural networks was implemented.


A conveyor belt is susceptible to static electricity as the belt is continuously pulled against the end pulleys. If electrical components are being conveyed, static electricity can be hazardous. Anti-static conveyor belt measures such as conductive belts or static control brushes should be considered to protect products.
