3. Introduction
 A conveyor system is a common piece of mechanical handling
equipment that moves materials from one location to another
 Conveyors are especially useful in applications involving the
transportation of heavy or bulky materials in Industries.
 Conveyers are also used in general material handling such as
those moving boxes along inside a factory, such as agricultural
materials, such as grain, salt, coal, ore, sand, overburden and
more.

4. Types of Conveyors
 Belt Conveyor
 Chain Conveyor
 Gravity Conveyor
 Powered Roller Conveyor
 Pallet Conveyor
 Overhead Conveyor
 Magnetic Slide Conveyor

5. Belt Conveyor
 Belt- are the most common type of conveyors and are very
versatile.
 Conveyor belts are used in a wide variety of material transport
applications such as manufacturing, food processing, and heavy
industry.

6. Working Of belt
The Belt is provided with two rollers . One is the Drive and other is
the Tension Roller. Drive roller is driven mechanically by a motor .
Tension roller can be moved forward and backward directions to
release or tight the belt with our requirement.

7. Belt Material
 Belts are typically made from cotton, canvas, Kevlar, nitrile,
nylon, polyester, polyurethane/urethane, PVC, rubber, silicone,
steel cord, Teflon, wire mesh or weave.

8. Design of belt
 The Belt consists of one or more layers of
material.Generally contains two layers.
1.) An under layer-to provide linear strength and shape
called a carcass(polyester, nylon and cotton)
2.) An over layer called the cover. (rubber or plastic
compounds)

9. Properties of Belt
 Flexibility
 Transverse rigidity
 Low mass per unit length
 High strength
 Simplicity and inexpensive
 Longer life
 Should not stretch under normal working stresses ,i.e., low
relative elongation.
 Wear resistant
 Fire resistant

10. Advantages of Belt Conveyor
 Belt conveyor can be used for abrasive, wet, dry, sticky or dirty
material.
 Higher capacity can be handled than any other form of
conveyor at a considerably lower cost per tonne per kilometer.
 Longer distances can be covered more economically.
 It can be horizontal, incline or decline or combination of all.
 It is considered a labor saving system that allows large volumes
to move rapidly.

11. Limitations
 The belt needs higher initial tension.
 Conveying of sticky material is associated with problems of
cleaning and discharge causing poor productivity.
 Higher elongation of the belt (4% elongation may take place at
the working load).

12. Conclusion
 Belt Conveyor systems can improve efficiency and help to
reduce repetitive lifting and carrying.
 Many industries use Belt conveyor systems to transport raw
materials and products through the stages of a process.
 We can say that the Conveyor system is the backbone of an
industry, if there is any failure in conveying system that needs to
be fix as soon as possible.
