Explanation for the tabular sections

Area related belt mass m"G

Data on the size parameter m"G apply only for the cover gauges as listed providing the following range of tolerances:
  • Tabular section 1.1 +1.7/-1.0 kg/m2
  • Tabular section 1.2 +/- 2.2 kg/m2
  • Tabular section 2.1 +1.2/-0.6 kg/m2
  • Tabular section 2.2 +1.5/-0.8 kg/m2
With other cover gauges, the following deviations per mm cover result:
  • Cover type X 1.10 kg/m2
  • Cover type Y 1.15 kg/m2
  • Cover type V 1.50 kg/m2
From the area related mass of the conveyor belt m"G the length related mass m’G can be calculated, taking into account belt width B in m according to the following equation:
  • m’G = B • m"G

Belt thickness dG

The data on belt thickness dG only apply for the cover gauges as listed above with a tolerance range of + 1.0/-0.5 mm for all tabular sections. The thickness of the belt carcass dGk can be calculated, taking the total cover gauge of top and bottom sides dDpges according to the following equation:
  • dGk = dG - dDpges

Minimum Pully Diameters (to DIN 22101)

The pulley diameters in a belt conveyor system depend on the design, on strains and on the type of splice of the conveyor belt. For determining the minimum diameters, the following pulley groups will be distinguished:
  • Group A: Drive pulley and other pulleys in the range of higher belt tensions
  • Group B: Deflection pulleys in the range of lower belt tensions
  • Group C: Snub pulleys (change in belt moving direction = 30°)
The minimum pulley diameter for Group A pulleys can be roughly determined by utilizing the thickness value of the tensile member in the belt as follows:
  • (DTR min)GR.A = Material Characteristic Value dGK
Tensilie member material in belt longitudinal direction
material characteristic value
E (Polyester)
108
P (Polyamide)
90
St (Steel cables)
145

A pulley diameter so obtained shall be rounded up to the next higher value of the table below, in which there are shown for each minimum values for group b and C, too.
Minimum pulley diameter DTR min without lining (Quoted in mm) depending on utilizing the admissible tension in the steady operation state.
