ABB wins order for variable-speed drive system

World Cement,

ABB has announced it has secured 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 in the PT Semen Bosowa Maros cement plant, which is located in Indonesia.

ABB previously delivered a cement grinding line to 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 maximises availability and reliability,” commented 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.
