89 Belt Tension Calculations W b =weight of belt in pounds per foot of belt length. 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
ادامه مطلبThe best way to lubricate a conveyor system is to use different lubricator tools for each component of the system. For example, for the pins inside the chain, a brush-style lubricator works the best. A brush-style lubricator has a reservoir on the top, and a brush on the bottom. When using the brush, you can open the reservoir, the oil will ...
ادامه مطلبThe major development, apart from self-advancing supports, allowing high production longwalls to evolve was the "Armoured Face Conveyor or AFC" which was originally developed in Germany and was frequently (less so nowadays) referred to as a "Panzer" conveyor.

ادامه مطلبWith a rubber mallet gently tap the bolts in the direction you need the belt to move. For example, if you need the conveyor belt to move to the left (when standing at the infeed end of the conveyor and facing the discharge end of the conveyor), gently tap the bolts on the left-hand side. This will result in the snub roller moving.

ادامه مطلبThe aspect ratio of a conveyor belt is the thickness of the top cover in relation to the thickness of the bottom cover. The problem with belts with poorly-designed aspect ratios is that the larger mass of rubber will shrink more than the smaller. Consequently, if a belt has an inordinately large top-to-bottom cover ratio, and the top cover ...
