Overland Conveyors
Belt
Conveyors is one of the cheapest mode for transporting bulk material from
one place to another, particularly for transportation from mines to the
plant or rail head/port. These long conveyors are normally installed following
the contour of the terrain which, in most of the cases, necessitates curves
in both horizontal and vertical planes. The development and popularity for
installation of overland conveyors has increased several folds in the past
decade owing to the availability of high strength steel cord belting and
sophisticated dynamic model analysis for assessing the behaviour of the
conveyor along the curves.
The long overland conveyors have resulted in multiple benefits to the actual
users in terms of lower capital cost, reduction in manpower requirement,
less maintenance and minimal operating cost. In case of routing the conveyors
over the terrain having firm ground, real civil footings are avoided and
the conveyors are supported over concrete sleepers to transfer the load
from the equipment.
Depending on the total length of the overland conveyor system, availability
of power along the route and accessibility to the site, the total length
is suitably divided and number of conveyors along the route are fixed. This
is carried out with the primary objective of reducing the cost of belt and
the cost of electrics.
With the customers seriously looking for an alternative to conventional
haulage of material from one place to the other through mobile equipment
involving lot more manpower, the overland long distance conveyor will be
the ideal substitute in the near future, reducing the dependence of actual
user on large manpower.
Macmet is the first engineering company in India to indigenously design,
supply, erect, test and commission a long distance overland conveyor for
the Kymore Works of ACC Ltd. to transport limestone from the mines to the
plant. The total route length of the conveyor is approximately 10.6 km covered
by 2 nos. overland conveyors of 5.3 km long each.
Macmet has currently undertaken design, supply, erection and commissioning
of a 3.7 km long cross country conveyor for Birla Corporation for their
Satna Cement Works. The conveyor will carry 1200 tons of limestone per hour
at a speed of 3.5 m sec.
Macmet has also undertaken design, supply, erection and commissioning of
a 9 km cross country conveying system for OCL Limited (Dalmia Group). The
system consists of 13 conveyors of 1000 mm belt width which will carry 750
tons of crushed limestone from Lanjiberna Mines to their Rajgangpur Plant.
The conveyors will be equipped with dustless chutes.
