For many decades, wire link conveyor belts have been successfully
used in the food industry, the steel industry and the chemical
industry. The reliability and durability of the belt are the main
reason for its success, combined with the various ranges of belt
materials and the sophisticated design, which makes it relatively
simple to make variant types of belts.
For example, the belt can easily provided with carriers, flights,
side plates or additional small rollers. Furthermore, the opening
between the wire links can be tailor made by de use of wire welded
underneath (most common), springs, rings or bushes. In this way,
the drain of the belt varies from 10 to 90 per cent.
Minimal drain openings of about 0,7 millimetres can be realised by
flattening the wire links. The space between the links is then
smaller than the diameter of the link itself. The diameter of the
wire links can vary from 1.5 millimetres for very light or fine
meshed belts to 4 millimetres for heavy duty applications.
OB wire link belts are available in widths of 50 to 7,000
millimetres and in nearly any desired length and have 3 basic
The type A” is the version with lamellar or welded edges. The belt
edges are generally formed by two ore more rows of plate links. The
wire links and plate links are assembled on the cross rod which is
fitted on both sides with a welded ring or a butted head.
The type B” is the version with chain edges. The belt edges are
formed by a hollow pin chain. The links and chains are assembled on
the cross rod which is fitted on both sides with a welded ring. The
chain is mostly kept in place by welding a ring to the outside as
well as to the inside of the chain. If the ends of the cross rods
are narrowed, the inside of the chain is secured by this
narrowingand the inner ring is cancelled.
The type C” is the version with roller edges. The belt edges are
formed by two rows of plate links with a roller in between. The
wire links, the plate links and the rollers are assembled on a
cross rod fitted with a welded ring.
Wire link belts can be used at conveyor speeds varying between less
than 1 metre per minute and 50 metres per minute, depending on the
processing situation and the intended working time. The strength of
the belt and, to some extent, its ability to resist wear, are
determined by the number of plate links and, if present, the chain
on the edges.
In the belt full plate links are mounted every 250 to 400
millimetres. The belt support can be placed underneath these plate
links. In some cases the belts can also be provided with plate
links in an eccentric version, which provides additional wear
Wire link belts are used in production processes having
temperatures from 100C to +600C.
Wire link belts are made of thin round wires with an eyelet on both
sides, to which they are hinged by means of a pin. In this way, a
thin one layer belt is created with the following advantages: It is
impossible for a product to form a deposit in ‘hollow spaces’ in
the belt, which are difficult to reach.
The weight of the belt can be kept relatively low. Process fluids
and gasses can go easily through the belt.The belt is easy to
clean. The belt is positively driven by means of sprockets or
driving drum. So there is no belt slip and it is possible to use
relatively small diameters. This all adds to a perfect belt run
The belt is easy to repair.
