ABB, the leading power and automation technology group, has won an order from Tianjin Cement Industry Design & Research Institute Co. Ltd, a subsidiary of SINOMA Group, for a highly energy efficient variable speed drive solution for a dual pinion ball mill at the PT Semen Bosowa Maros cement plant in Indonesia. The equipment will be delivered in March 2016 and commissioned in the third quarter of 2016. The order was booked in the third quarter of 2015.
ABB was selected for that project because the end customer had been satisfied with earlier deliveries for the first cement grinding line at the plant, including a gearless mill drive (GMD) and a vertical mill with ABB slip ring motors.
“ABB’s solution was favored for several reasons, not least because of the high-level of efficiency offered by the permanent magnet motors used and the absence of a gearbox in the system, which maximizes availability and reliability” said Rachid Hamdani, Project Director of PT Semen Bosowa Maros.
ABB is a leader in drive systems for grinding applications with more than 45 years of experience in delivering ring-geared and gearless mill drives to the cement and mining industry.
This will be the first drive system for a grinding application with permanent magnet motors in this power and torque range. The solution has the highest efficiency among all variable speed drive systems and will raise productivity at the plant, while minimizing electricity consumption.
