P. Sabapathy developed the wet grinder in Coimbatore in 1955.[12][13][14] Sabapathy introduced the grinders to other cities such as Chennai and Madurai.[14] In 1963, P. B. Krishnamurthy started Lakshmi Grinders which led to the commercial popularity of wet grinders.[15] In 1975, R. Doraiswamy invented the tilting wet grinders.[15][16] L. G. Varadaraj introduced the table top wet grinders which replaced grinders which had to be placed on the ground.[15][17]
Industry
Earlier wet grinders
As the product was invented in the city, Coimbatore naturally emerged as a center for the manufacture of wet grinders. The availability of raw material in the form of granite stones, electric motor manufacturing units and the necessary heavy equipment such as lathes, drilling and milling machines used in manufacturing aided the development of the industry.[13]
The city contributes to about 75% of the 1 lakh total monthly output of wet grinders in India.[4] The industry employs 20,000 people directly and provides indirect employment to 50,000.[13] In 2011, the cluster had a yearly turnover of ₹225 crore (US$28 million) which grew to ₹2,800 crore (US$350 million) in 2015.[4]
Recent developments
In 2007, the Government of Tamil Nadu opened a center for manufacturing raw materials for wet grinders and a research center built at a cost of ₹28.8 million (US$360,000).[18] The industry grew over ten times in the last few years due to procurement of nearly 22.5 million wet grinders by the Government of Tamil Nadu for free distribution to green family card holders.[4][19] In 2015, the Government of Puducherry announced distribution of free wet grinders to 3.37 lakh families for which it plans to procure wet grinders at a cost of ₹120 crore (US$15 million).[20]
Wet grinders are mainly sold through retail channels with the manufacturer distributing it through intermediaries. Since 2014, the sales through e-commerce channel has grown considerably helping in bulk sales and brand building.[21]
