Conveyor
Belt Idlers / Rollers : Troughing and Return Rollers
Conveyor belt rollers are cylindrical rollers with a steel shaft
running through the centre. They run on bearings and are installed
into a frame that carries a conveyor belt. The rollers support the
belt, carrying the weight of the product to be moved (Troughing
rollers) as well as supporting the returning empty belt (return
rollers). The rollers have steel tubes with high-grade polypropylene
bearing housings.
All non-metal components are manufactured from high-grade polypropylene
for its structural stability and toughness.
The uniqueness of BeltMaster’s patented design relates to
the sealing arrangement protecting the bearing from the penetration
of dirt, as well as the quick assembly method.
The unique stub-axle enclosing the shaft end is produced in different
shapes to enable the rollers to fit into all existing conveyor belt
structures still in use on mines in South and Southern Africa. BeltMaster
is able to supply the standard SABS 18mm across flat (a/f), 14mm
a/f, hex-type, rubber-type and garland -type stub axles for the
rollers. BeltMaster also produces standard impact idlers.
The conveyor rollers are produced in a complete range of sizes,
ranging from rollers for a 400mm width conveyor belt, through to
those for a 2400mm width belt.
The grease packed into the bearing and the labyrinth seal is a
specially formulated compound that has water repellent properties
and a low friction coefficient. The combination of the grease and
labyrinth seal design allows the bearing to remain sealed under
harsh conditions, greatly extending the life of the roller. Current
production capacity is set up for 500 rollers per day.
Our patented design on the conveyor belt rollers allows for an
innovative assembly system, as well as an extremely efficient seal,
keeping dirt and moisture away from the bearing. The design has
proved its success under the harshest of environments – from
the salt mines in Botswana, to the humidity of sub-tropical Richard’s
Bay harbour on the Indian Ocean coast of South Africa. The rollers
are used extensively in the coalmines of Mpumalanga, KwaZulu Natal,
NorthWest and Northern Province in South Africa, and are exported
to Swaziland, Botswana and Mozambique. |
