Power and automation tech-nology group ABB has won an order from Tianjin Cement Industry Design & Research Institute, a subsidiary of Sinoma Group, for a highly energy effi- cient variable speed drive (VSD) solution for a dual pinion ball mill at the PT Semen Bosowa Maros cement plant, in Indonesia.
Equipment was delivered in March and will be commissioned in the third quarter of this year.
ABB was selected for the 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 and a vertical mill with ABB slip ring motors.
“ABB’s solution was favoured 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,” says cement manufacturer PT Semen Bosowa Maros project director RachidHamdani.
ABB has gained much expert-ise in the area of 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 VSD systems and will raise productivity at the plant, while minimising electricity consumption.
ABB’s power and automation technologies enable utility, industry, transport and infrastructure customers to improve their performance while lowering environmental impact. The ABB group of companies operates in roughly 100 countries and employs about 140 000 people.
