Conveyor belts

Conveyor belts

They find their application in almost all industries as the means used to accelerate the transport, handling with products and overall production efficiency. These belts are often a direct part of the production facilities and technological units. These are mainly the wire conveyor belts, but also the hinghad belts made of metal or plastic.

 

 

Basic information

 

Types of wire belts and their description

The basic types of wire belts with their dimensions are shown in the picture No. 1:

 

Dimensions

 

a = pitch (distance between centres of two cross rods)

b = pitch - spacing (distance between centres of spiral wires)

c = diameter of spiral wire or wire loop

d = diameter of cross rod

m = mesh (distance between wires)

m1 = length of ending mesh

I = number of cross rods per pitch

L = length of belt

S = width of belt

 

Materials

Belts are produced from various materials according to their intended use. The most common materials are mild steel of standard quality, galvanised steel, stainless steel, high temperature or acid resistant steel. Metal belts can be used for temperatures from

- 200 °C to + 1200 °C.

1. Mild steel (black)

The advantage of this material is its reasonably high strength in tension at normal temperatures and its relatively low price. This material can be used successfully for belts which are not exposed to any moisture and where the working temperature does not exceed approx. 350 °C.

2. Galvanised steel

This steel has the same qualities as the previous material, but because of the  galvanised wires it can be used in a moist environment.

3. Stainless steels

These are compositions of iron and chrome or of iron, chrome and nickel. In the first case it is the steel resistant to corrosion caused by moisture  and in the second case it is the steel resistant to acids and temperatures up to approx. 700 °C. The most commonly used qualities of materials are DIN 1.4301, 1.4401 a 1.4310.

4. High temperature resistant steels

Again these are chrome-nickel steels which due to their chemical composition, are able to withstand temperatures from 600 °C up to 1150 °C. The most commonly used types of materials are made of steel with content of 2 - 5% Cr for temperatures about 600 - 700 °C and for higher temperatures DIN 1.4828, 1.4841 1.4864 (Incoloy DS) and 1.4862 (Nicrofer).
