INTRODUCTION
A conveyor system is a commonpiece of mechanical handlingequipment that moves materials
from one location to another.
Conveyors are used for movingsupplies in a fixed line of travel.

TYPE OF CONVEYORS
In construction industry, mostconveyors are made by beltconveyor.
Two basic types of conveyors:
- gravity-type roller or wheelconveyor
- portable power-driven beltconveyor.

CONVEYORS
The gravity-type roller or wheel conveyor
can be installed with one end lower than theother to take advantage of gravity or it can be
installed level and the load pushed alongmanually. Several sections can be put together and
developed into a continuous system formovement of material on the ship duringunderway replenishment or verticalreplenishment.
The conveyor can also be used on piers, instorerooms, or wherever a steady flow of suppliesis desired.

CONVEYORS
The power-driven belt conveyor consists of an endless belt mounted on a frame
and driven by a pulley connected to a drivemotor.
The belt travels over a series of rollers or asliding bed. The belt conveyor can be used to transport
materials over a fixed path of travel up inclines ofas much as 25 degrees.
It has less mobility and flexibility than truck andscrapers Mainly used when large volumes of material are
to be moved along one route.

Other Types of Conveyor
Truck Conveyor: The Truck Conveyor is used with end dump
trucks to convey material from the truck up to 8ft to the side.
The independent controls allow the operator toconsistently place the material exactly where it isneeded by extending or retracting the conveyor .
This unit is self contained with diesel hydraulicpower for versatility.
An easy and fast connection to the truck hitch, avariable side to side conveyor length andreversible belt direction make this a productivetruck attachment.

Other Types of Conveyor
Screw Conveyor: Moves material of granular or fluid consistency by
a helical screw shaft that rotate concentricallywith a axis of a hollow pipe tube or open trough.
It can move material up an incline of 15 degreesup to 45 degrees with the horizontal. Frequently used to move cement in a concrete
plant. When space allows, this is a very economical
method of elevating and conveying. as the angle of inclination increases, the
allowable capacity of a given unit rapidlydecreases.

Compressed Air/Pneumatic Conveyor:
For moving cement/finely ground material
With a compressed air in a pneumatic pipe or
hose The cement hog is like a vacuum cleaner that
chews into loosely packed cement in a bargesstorage bin or other such container.
Is more expensive than other types of conveyorin both installation and operating cost.
