Mobil oil ensures energy savings for Çimko Cement
1 min read
Turkish cement maker Çimko Cement is said to have experienced significant reductions both in energy consumption and gearbox operating temperatures at its Narli plant following a switch to Mobil SHC Gear gear oil.
As a result, Çimko Cement decided to use Mobil SHC Gear in all elevator gearboxes and in the rotary kiln gearboxes to help reduce unscheduled downtime, improve the energy efficiency of equipment and increase productivity.
The company looked to reduce operating costs and improve energy efficiency of its equipment. Following an initial 26-month-long trial with Mobil SHC Gear 460 on its limestone conveyor driver, which is claimed to have resulted in significant reductions in energy consumption, Çimko Cement undertook another trial for an energy efficiency comparison.
The second 16-month-long trial on two gearboxes driving the raw material silo elevator delivered average energy savings of 2.3% compared to a competitor's fully synthetic oil, following a switch to Mobil SHC Gear 320.
Mobil SHC Gear 320 has also demonstrated an average 5°C reduction in gearbox temperatures after 11,000 hours of service. Reduced fluid friction in gears – the result of low traction properties of the synthetic base stocks used in Mobil SHC Gear oils – produces lower operating temperatures and can help improve gear efficiency.
In addition, the high viscosity index of Mobil SHC Gear oils is said to deliver less change in viscosity with changes in temperature, and during the initial Mobil SHC Gear 460 field trial no change in viscosity was recorded after 16,000 hours of service. This enabled a wider operating temperature range and improved low temperature start-up. There was also no indication of oxidation after 16,000 hours of service, which can help extend oil drain intervals, reducing oil consumption and lowering maintenance costs.
