Indonesia: ABB, a 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 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. ABB was selected for that project because the end customer is 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 favoured 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 maximises availability and reliability," said Rachid Hamdani, Project Director of PT Semen Bosowa Maros.
This will be the first drive system for a grinding application with permanent magnet motors in this power range. The solution has the highest efficiency among all variable-speed drive systems and will raise productivity at the plant, while minimising electricity consumption.
