Eco-Friendly Sprayable Girth Gear Lubricant for
Cement Industry
Introduction
Open gear drives are common methods
of power transmission for rotating equipment. Modern
drives are often the most economical drive alternatives
when high load carrying capacity, and long service life
under severe shock loading conditions are required.
These characteristics have made open gearing a popular
drive for rugged, rotating equipment such as grinding
mills, Kilns driers etc. These equipments are lubricated
with girth gear lubricants. In cement plant, generally
girth gears are used for crushing raw materials. These
equipments operate under different environment and operating
conditions. A wide variety of lubricants are presently
employed.
Currently, sprayable greases are used
for the lubricant of girth gears in cement plants. The
consumption of these greases is about 500 600
metric tons p.a. costing around Rs. 20 30 crores.
Moreover, they are entirely imported. These lubricants
are mineral oil based and non-biodegradable. On account
of environmental concern and government regulations,
these lubricants are in urgent need of replacement.
The practice of using copious types of lubricant is
no longer acceptable. End users are demanding more environmentally
acceptable lubricants that are economical as well as
easy to dispose off.
Keeping these requirements in mind,
the Indian Institute of Petroleum (IIP), Dehradun has
developed eco-friendly, biodegradable & sprayable
girth gear lubricant for cement plant. The performance
of this product is better than the existing commercial
product.
