Abstract: Pipe conveyors are becoming more popular in
the bulk material handling sector. They are applied when
the installation of a belt conveyor is required in difficult
topographical conditions, rough weather conditions, and for
the transportation of dusty, contaminated, and toxic
materials. New innovations in the pipe conveyor and belt
are advanced to elaborate the growth in its capacity, length
and complexity of pipe conveyor . Enhanced belt
construction can offer better stability during horizontal
curves and resistance to twist. LRR pipe conveyors with
arubber compound can significantly lower the power
consumption and belt tension, producing capital and
operation cost savings. Dynamic analysis systems , are used
to analyse the conveyor’s starting and stopping
behaviourwhich in further can improve the design and
reliability of long pipe conveyor systems. For these three
aspects, technical backgrounds and field installations as
examples are discussed.

PROBLEM DISSCUSSED
Manikgarh cement has 7.8 km line from the mines to the
unloading station . For the Unit I there is ropeway bucket
system with each capacity of 2 MT and the total no. of
buckets are 300 having and total capacity of 600 TPH.
Inspite of this it requires more maintaince cost and power,
energy consumption and may cause accidents and failures
due to misalignment of bucket.Similarly, a new system has
been setup for unit II which comprises pipe conveyor
which has a total capacity of 750 TPH and is more efficient
as compared to ropeway system.
INTRODUCTION
Belt conveyors mainly for transporting materials, and are
widely implemented in the mining, power generation,
cement, ship port and industrial plants for several decades.
The main benefit of belt conveyors compared to other
material handling machines like trucks, trains and barges
is the higher efficiency in the mechanical system, energy
consumption and total cost over the long term, especially
when conveyor system is design optimized . Trough belt
conveyor is the ubiquitous type of belt conveyor. There are
other belt conveys serving more specialized purposes, like
pipe conveyors or tubular conveyors, high incline or high
angle conveyors, wheel-on-rope type of conveyors like
cable conveyors and Ropecon. Pipe conveyor was first
installed in 1980s in Japan , the actual advantages of using
pipe conveyor was its capabiitt to accomplish sharp
curves and seal the transporting material. Rolling the belt
into the pipe shape separates the material from the
environment. It also minimizes the area and moment of
inertia, which facilitates the bending of the pipe belt over
horizontal and vertical curves. Over the last fifteen years,
pipe conveyor saw not only increased number of
installations and growth in the size and complexity of the
system, but also better recognition by the general material
handling sector as a feasible material handling system.
India and China now represent the biggest market for pipe
conveyors. In south east Asia , Australia and South
America, a few major pipe conveyor installations are either
operating, being erected or under planning. If these initial
high profile systems get to be successful, it is reasonable to
expect that more pipe conveyors will be planned and
installed during the next decade in these areas. In further
decades south east Asia, Australia and south America
important new markets for pipe conveyors.
Inspite its obvious benefits, pipe conveyors have
additional costs and engineering problems compared to
other conveyors. Total cost is generally double comparable
to other conveyors due to increased number of idler
rollers, bigger drive size, and higher belt cost. Similarly, for
operating cost it is high due to increased power
consumption. One of the main engineering and
maintenance concerns is how to control the belt rotation,
twist and collapse, especially when the conveyor routing
has small radius curves. The manufacturing of long length
and large ton capacity pipe conveyors requires
specialized engineering that is not readymade available to
the general professionals in the material handling sector.
