Aug 22, 2010· This article will discuss the methodology for the calculations of belt conveyor design parameters with one practical example of the calculations and selection criteria for a belt conveyor system. Calculations include conveyor capacity, belt speed, conveyor height and length, mass of idlers and idler spacing, belt tension, load due to belt, inclination angle of the
conveyor belt is normally referred to as the "carcass." In a sense, the carcass is the heart of the conveyor belt since it must: 1. Provide the tensile strength necessary to move the loaded belt. 2. Absorb the impact of the impinging material being loaded onto the conveyor belt.
replacing the belt as this might result in damage. For the multiple belt drive, always change all belts at the same time. Failure to do so may shorten the service lives of the belts or cause personal injury. Warning Do not burn belt within a closed space, or hazardous gas can be produced, and you might die or suffer serious injuries by toxicosis.

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
Types of Belt A / B / C / Z Section Belts: These type of belts are known as classical vee belts. If the section is suffixed with an 'X', this indicates that the belt is cogged to allow fitting at tighter angles. SPA/SPB/SPC/SPZ Section Belts: SP denotes that the belt is a wedge belt. Again, an 'X' suffix indicates a

The following method is used to determine the tension at any point along the conveyor: 1. Calculate the length correction factor. 2. Look up the mass of moving parts in Table 10. 3. Calculate the mass of the load from the design capacity and the belt speed. 4. Calculate the maximum effective tension under constant speed operation.
In the case of perforated belts please note: calculate the load-bearing belt width b 0 based on the number of per-forations which decrease cross sec-tions. Staggered perforations in partic-ular can reduce the load-bearing belt width considerably. Reduce the figure for the load-bearing belt width b 0 by a further 20 % to take tolerances for per-
Belt Widths The belt widths are as follows: 18, 24, 30, 36, 42, 48, 54, 60, 72, 84, and 96 inches. The width of the narrower belts may be governed by the size of lumps to be handled. Belts must be wide enough so that any combination of prevailing lumps and finer material does not load the lumps too close to the edge of the conveyor belt.

Belts have a higher capacity and longer belt life than trapezoidal belts. It's difficult to make a true quantitative comparison between the backlash of a trapezoidal tooth drive and PowerGrip GT3 drive due to the difference in "pulley to belt tooth" fit (see Figure 3 ).
V-Belts will transmit power satisfactorily over a wide range of tensions. An experienced user can develop a feel when a drive is tensioned within this range. However, in order to optimize belt life and performance and to avoid undue stress on shafts and bearings it is desirable to calculate and measure belt tension based on drive loads.
Calculations while a theory is based on experiments, which are an exhaustible source of knowledge. A theory and calculations are inseparably bound. Without a verified theory taking all the factors into account one cannot make accurate calculations and so one cannot optimally design a belt conveyor. Tension force is calculated
