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.
