Eveready Mills saves 10 % energy and a lot of money
“We do not inherit the earth from our parents, we borrow it from our children” – Chief Seattle. So it is important to conserve energy and to investigate solutions for energy savings. Rieter has followed this direction to innovate the concept of “ECOrized” in its product portfolio. The Indian company Eveready Spinning Mills Pvt Ltd. realized a 10 % energy saving in ring spinning with the suction tube ECOrized. They regard this solution as a sustainable money saving innovation.
In January 2013 Swiss Government handed over to Rieter the “Watt d’Or” award for the new suction tube ECOrized as “excellent energy project, plausible concept and outstanding innovation”.
The suction tube ECOrized for Rieter ring spinning machines replaces the existing suction tubes to reduce suction power by about 50 %. Each spinning position currently features a suction opening for extracting ends down and tangles. However, this is only needed in very few cases. So why not use a suction tube that opens fully only when necessary? The suction tube ECOrized offers this advantage and the resulting energy savings. Existing suction tubes can simply be replaced. Considerable energy savings are achieved.
Winner of Rieter’s suction tube “ECOrized”
Eveready Spinning Mills Pvt Ltd - Unit 4 located in Dindigul, Tamilnadu – South India is one of the five winners of Rieter’s “ECOrized” competition. They received a free kit of ECOrized suction tubes with free delivery and installation for one of their 18 ring spinning machines G 32, each with 1 440 spindles.
Power study in ring spinning
Three consecutive trials were undertaken by Eveready. The study compares power consumed by the standard suction tube and the suction tube ECOrized. On the G 32 with the suction tube ECOrized the frequency could be reduced to 35 Hz by a frequency inverter. The machine was running normally with good overall performance. The energy consumption of this machine was reduced by nearly 10 %.
Eveready comments on the cost saving in practice
Mr. S. Saravanakumar, executive director Eveready, gave following statement. “Any saving in the energy cost impacts the cost of yarn manufacturing positively. Many controlled studies in our mill on G 32 ring spinning machine indicate a definite 8 to 10 % saving in the total ring spinning power consumption when we use Rieter’s suction tube ECOrized.
We are also contemplating to retrofit the suction tube ECOrized on the remaining G 32 ring spinning machines. The suction tube ECOrized is a sustainable, money saving innovation in ring spinning and proved worthwhile for the company.”
