This document details ABB's work for Qassim Cement Company (QCC) in Saudi Arabia, covering the upgrade of three production lines. It outlines the replacement of 50 Hz equipment with 60 Hz systems, the installation of new 33 kV and 6.3 kV switchgear, and the implementation of an AC800xA automation system.
The report also describes the commissioning, training, and short‑outage strategy used to keep plant downtime to four weeks for the raw mill and two weeks for the cement mill, as well as the integration of local control rooms and the use of ACS1000, ACS800 and ACS 2000 drives.
| Main station switchgear type | ZX1 double bus bar, 33 kV |
|---|---|
| Medium voltage switchgear | 6.3 kV |
| Drive model for raw mill and cement mill | ACS1000 Multidrive |
| Drive model for 400 V level | ACS800 Multidrive |
| ACS 2000 drive rating | 315 kW, 6.0‑6.9 kV |
| Number of electrical motors at QCC | approximately 2 000 |
Line 1 was upgraded from 50 Hz to 60 Hz.
ABB installed an 800xA control system with AC800M controllers.
QCC operates roughly 2 000 electrical motors, most supplied by ABB.
The upgrade was limited to a four‑week period for the raw mill and a two‑week period for the cement mill.
