Christian Pfeiffer has contracted Siemens to supply an integrated drive system and automation technology for the new CMS Cement plant in Kuching in the state of Sarawak, Malaysia.

CMS Cement is adding a new mill to its existing clinker production plant to turn the facility into an integrated cement plant, thus increasing its capacity to 2.75Mta. Christian Pfeiffer is acting as the general contractor and will supply the new mill, and contracts have already been announced for the new silo and packaging facilities. Now, Siemens has released details of its involvement in the project.

Siemens scope of supply
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 5.6 MW for the cement mill’s main drive and a 500kW, a 400kW and a 160kW motor driven using Sinamics G150 converters for the process gas fan, separator and mill filter fan, respectively.

Siemens has also supplied a Flender girth gear (DMG2) including drive couplings and auxiliary drive with extremely high performance density for use in the new plant.
Automation

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, making a major contribution towards process optimisation. Once the milling process has stabilised following commissioning, CMS will also take over additional control functions using Advanced Process Control technology components, allowing the manufacturer to benefit from a consistently high level of product quality and reduced staffing costs for operating personnel.

Installation monitoring, commissioning and staff training are being carried out on site by Siemens Malaysia.
