Grease is a fine dispersion of an oil-insoluble thickening agent - usually
soap in a fluid lubricant which is generally mineral lubricating oil. The
soap is made up of fatty acid, tallow or vegetable oil saponified with
alkali which can be hydrated lime, caustic soda, lithium hydroxide or
aluminum hydroxide. The lubricating oil component is refined base
oil-naphthenic, of medium viscosity index, or cylinder oil stock.
Structurally grease is a water-in-oil emulsion. Its appearance
is smooth, mostly translucent, soft or hard
Properties essential for performance of grease are structural stability,
lubricating quality, low and high temperature performance (which are
provided by the selected lube oil base stock), where as properties such as
water resistance, high temperature quality, resistance to break down through
continuous use and ability of grease to stay in place are provided by the
Additives eg. Graphite, modified clay, asphalt, oxidation and corrosion
inhibitors, extreme pressure additives melybdenum disulphide etc. are used
to impart specific properties as required by end application.
Unit Processes And Unit Equipment In Grease Manufacturing
- Pumping of raw material from storage tanks into day tanks
- Raw materials measurement by volume or weight using weighing scales,
meters, tank gauges etc.
- Preparing the soap by heating and premixing fat and lube oil in
kettles with counter rotating scraper stirrer operated by motor and
- Cooling of the prepared soap and balancing with oil to prepare grease
in a cooling kettle.
- Formation of grease structure by dispersion in a milling machine
under controlled moisture and temperature parameters.
- Deareation using deareator.
- Filtering through filter.
- Filling using weigh scales/ filling machines.
- Instrumentation - indicators/recorders for temperature and pressure.
- Pumps- gear and centrifugal for lube oils, vegetables oils, liquid
soap and grease at various stages of manufacturing.
- Material handling equipment like hoist, pallet trucks, and fork lifts
to handle solid fats, additives, alkali, drums etc.
- Safety and fire protection devices.
- Lab equipment
- Utilities like hot oil system, cooling system, air compressor, water
Type Of Grease
Used for simple bearings, general purpose machinery and chassis lubrication
for normal temperature applications. At about 80 deg. C. water binding the
oil and soap is lost so they separate and lubrication property is lost.
Calcium based greases are water resistant and are low in cost.
Used quite generally for ball and roller bearings. Exceptionally good for
sealed for life bearings. Exceptionally good for sealed for life bearings.
Suitable for high temperature conditions up to 175 deg. C. Soda base greases
are soluble in water. They have natural anti-corrosion and good rust
protection properties. They do not separate at high rotational speed. Their
cost is moderate.
Their characteristics are similar to calcium base greases - water
resistance and normal temperature applications. They have exceptional
stringiness and adhesive properties. Generally they are semi fluid products,
clear and transparent. They are used when adhesiveness is important.
Having combination of exceptionally good lubricity, high
temperature stability, with good water resistance. These greases are
selected for multipurpose industrial and automotive application. They are
stable up to 175 deg.C. Where many types of machines or equipment are in
operation over widely varying conditions, an inventory of several greases
and grades must be maintained if only single purpose greases are used. Here
lithium base multipurpose greases are attractive - offering in a single
product- combination of many advantages of single use greases. Cost of
lithium base is moderately high.
Not much in use due to high cost and time and other manufacturing factors
to produce to produce soap. They have outstanding shear stability and have
multipurpose applications similar to lithium base greases.
Extreme Pressure (EP):
EP agents are added to conventional greases for use where unit pressures
are high or where shock loads may be encountered. EP agents are lead,
chlorine, sulphur or phosphorus compounds. Molybdenum, disulphide (Moly) is
widely for automotive lubricating greases.
Conventional soap such as Calcium soap plus salt of low molecular weight
acid such as calcium acetate provides thickener system of unique
properties/characteristics eg. superior anti-wear, extreme pressure, good
oxidation stability, resistance to melting at high tempera getable oil
saponified with alkali which can be hydrated lime, caustic soda, lithium
hydroxide or aluminum hydroxidture.
