Calculate the drive tension per width of belt by taking the Td figure found in step 1 and dividing by the belt width 3 If using a belt at an elevated temperature multiply the maximum allowable tension per foot of width (given in the conveyor specification tables) by a factor from the table below to get the working tension at an elevated temperature
Bearing Load Calculation 4 3 Mean load The load on bearings used in machines under normal circumstances will in many cases fluctuate according to a fixed time period or planned operation schedule The load on bearings operating under such conditions can be converted to a mean load (Fm) this is a load which gives
The angle of surcharge of a material is the angle to the horizontal which the surface of the material assumes while the material is at rest on a moving conveyor belt This angle usually is 5 degrees to 15 degrees less than the angle of repose though in some materials it may be as much as 20 degrees less
Belt Load At one time when the load is known per square foot: P= G 1 x C(in feet)x W (in feet) At one time when load is known by pounds per hour: P=G 2 /(S x 60) x C(in feet) Horsepower Level Conveyors: HP=(F x S x (P+M))/33 000 Inclined Conveyors: HP=((P x B)+(P+M)x F x S)/33 000 Effective Tension Pull needed to move belt and load horizontally: E= F x (P+M)
