| All types of materials change dimensions when the
temperature changes. Therefore you have to consider this when calculating
a belts dimension and the frame constructions. |
| |
| |
|
|
| |
| |
| Below are the relevant factors for calculating
the expansion/contraction factors of our conveyor belt. |
| |
| Belt |
Expansion/Contraction (mm/m/°C) |
| |
|
| Polypropylene (PP) |
0.12 |
| Prolyethylene (PE) |
0.22 |
| Polyacetal (POM) |
0.09 |
|
| |
| |
| Wear strip |
Expansion/Contraction (mm/m/°C) |
| |
|
| U and V profile (PEHD) |
.14 |
|
| |
| |
| Frame Material |
Expansion/Contraction (mm/m/°C) |
| |
|
| Aluminium |
0.02 |
| Stainless Steel |
0.01 |

| Thermal Expansion
/Contraction Formula |
| |
|
| |
E = L x ( T2 - T1 ) x K |
| |
|
| |
C = L x ( T2 - T1 ) x K |
| |
|
| |
|
| |
E = Expansion (mm) |
| |
C = Contraction (mm) |
| |
L = Length/Width of belt (m) |
| |
T1 = Normal temperature (21°C) |
| |
T2 = Working temperature |
| |
K = Coefficient |
| |
|
| |
|
| Example: |
| |
|
| |
17 m long belt, 1345 mm wide.
Normal temperature of 21°C |
| |
and working temperature
85°C. |
| |
|
| |
Length: E = 17 x ( 85 - 21 ) x 0.12 = 130.56 m |
| |
|
| |
Width: E = 1.345 x ( 85 - 21 ) x 0.12
= 10.33 m |
