INTRODUCTION
AND IMPORTANCE
• Material handling is a necessary and
significant component of any productive activity.
• It is something that goes on in
every plant all the time.
• Material handling means providing
the right amount of the right material, in the right condition, at the right
place, at the right time, in the right position and for the right cost, by
using the right method.
• It is simply picking up, moving, and
lying down of materials through manufacture.
• It applies to the movement of raw
materials, parts in process, finished goods, packing materials, and disposal of
scraps.
• In general, hundreds and thousands
tons of materials are handled daily requiring the use of large amount of
manpower while the movement of materials takes place from one processing area
to another or from one department to another department of the plant.
• The cost of material handling
contributes significantly to the total cost of manufacturing.
DEFINITIONS
• “Material handling is the movement
and storage of material at the lowest possible cost through the use of proper
method and equipment”.
• “Material handling embraces all of
the basic operations involved in the movement of bulk, packaged, and individual
products in a semisolid or solid state by means of machinery, and within limits
of a place of business”.
• “Material handling is the art and
science of moving, storing, protecting, and controlling material”
Objectives
The primary
objective of a material handling system is to reduce the unit cost of
production. The other subordinate objectives are:
1. Reduce
manufacturing cycle time
2. Reduce
delays, and damage
3. Promote
safety and improve working conditions
4. Maintain
or improve product quality
5. Promote
productivity
ü Material should flow in a straight
line
ü Material should move as short a
distance as possible
ü Use gravity
ü Move more material at one time
ü Automate material handling
6. Promote
increased use of facilities
ü Promote the use of building cube
ü Purchase versatile equipment
ü Develop a preventive maintenance
program
ü Maximize the equipment utilization
etc.
7. Control
inventory
Types of
Equipment
Conveyors
Powered Industrial Trucks
Cranes
Slings
Conveyer belts
Screw conveyers
• A screw conveyor or
auger conveyor is a mechanism that uses a rotating
helical screw blade, called a “flighting”, usually
within a tube, to move liquid or granular materials. They are used in many bulk
handling industries.
Pneumatic
conveyers
• Pneumatic conveying systems are operated by gas
under pressure. They have improved agitation caused by a controlled process of
material addition which greatly reduces batch time.
• A pneumatic system’s
contained transfer can charge powder into a vessel under vacuum or pressure,
and even with liquids (e.g. solvents) present in it.
