Malaysia: Christian Pfeiffer has contracted Siemens to supply an integrated drive system and automation technology for the new CMS Cement plant in Kuching, Sarawak State.
CMS Cement is adding a new grinding mill to its existing clinker production plant to turn the facility into an integrated cement plant, increasing its capacity to 2.75Mt/yr. Christian Pfeiffer is acting as the general contractor and will supply the new mill. Contracts have already been announced for the new silo and packaging facilities.
The Siemens' Integrated Drive System to be supplied to the plant consists of low and medium voltage motors together with the associated Sinamics drives, including the required converter transformer, starter, compensation system and gearbox. The supply package contains a slip ring motor of 5.6MW for the cement mill's main drive and 500kW, 400kW and 160kW motors for the process gas fan, separator and mill filter fan, respectively. The motors will be driven using Sinamics G150 converters.
Siemens has also supplied a Flender girth gear (DMG2), including drive couplings and auxiliary drive with extremely high performance density. Process control and monitoring will be taken care of by the Cemat process automation system. Based on Simatic PCS 7, this allows comprehensive transparency throughout every phase of the cement manufacturing process.
Once the production process has stabilised following commissioning, CMS Cement will take over additional control functions using Advanced Process Control technology components. Installation monitoring, commissioning and staff training will be carried out on site by Siemens Malaysia.
