CMS Cement Sdn Bhd As a core business of Cahya Mata Sarawak since 1974, CMS Cement now enjoys the distinction of being an integrated cement manufacturer, providing quality cement for customers across Sarawak through a well-established and efficient delivery system.
Our Products Portland Cement
Portland Cement (PC) is a multi-purpose cement that is most commonly used in general construction. When mixed with water, sand and aggregates, the grey coloured PC powder hardens into the material used for concrete construction. At CMS Cement, quality is guaranteed. PC produced by CMS Cement exceeds the quality requirements specified in the Malaysian Standard MS EN 197-1 which is equivalent to ASTM C150. Masonry Cement
Cemplast is the registered brand name for Masonry Cement produced by CMS Cement. It is manufactured in accordance to Malaysian Standard. The special plasticizing material incorporated in Cemplast improves the workability and water retention properties and eliminated the need to add hydrated lime to produce a workable, durable and economical mortar. Cemplast is designed specifically for producing mortars used for brick/block laying, interior and external rendering and plastering and other masonry applications.
To provide our customers with greater choices and flexibility to suit their required needs, CMS Cement carries out R&D to produce other types of cement such as Portland Composite Cement and Portland Fly Ash Cement.
International Recognition CMS Cement has been awarded multiple certifications and awards as proof of its commitment towards quality, environment and occupational safety and health. All plants are certified to ISO 9001, ISO 14001 and OHSAS 18001. All laboratories are accredited to ISO/IEC 17025. CMS Cement’s strict quality control at all stages of manufacturing, as well as, stringent testing, control and monitoring procedures ensures the quality of its finished products.

The Process Step 2
Crushing & Storage of Raw Materials
Limestone, shale and sandstone form the main raw materials to manufacture clinker. For CMS Clinker, all three materials are quarried within its plant at Mambong, ensuring a continuous supply of quality raw materials.
Different crushers are used for the three raw materials to obtain aggregates of less than 60 mm in size - limestone is crushed by a hammer crusher, shale is put through a roller crusher and sandstone is crushed by a portable jaw crusher. The resulting crushed materials are then stored in silos and storage halls.
Pre-Grinding & Grinding This next step involves a further reduction in size of the raw mix (90%), limestone (8%) and copper slag (2%). These raw materials are ground with a vertical roller mill (VRM) to achieve an 88% passing rate through a 90 micron sieve. The resulting fine raw meal powder is then blended in the blending silo and transported as kiln feed to a pre-heater. The coal used as fuel for the kiln is also ground using a vertical roller mill to a fine powder which has an 80% passing rate through a 90 micron sieve.
From the kiln, the hot clinker is cooled to a temperature of 100°C at the ‘walking cooler’ which uses ten cooling fans. The clinker is further crushed to smaller balls of less than 25 mm diameter in size using a hammer crusher before being transferred using the pan conveyor system to the clinker silo.
Manufacturing cement begins with mixing the raw materials (clinker, gypsum and other suitable minor constituents such as limestones) at a pre-determined mixing ratio. The composition is then conveyed to two chambered tube mills filled with steel balls where it is ground to the required fineness. At the Pending grinding plant, raw materials are fed
Cooling & Storing
Mixing & Pre-Homogenising Limestone (making up 78% of the raw material), shale (12%) and sandstone (10%) are mixed together and pre-homogenised using a boom stacker. This process results in raw mix. A reclaimer is then used to transfer this raw mix.
Pre-heating & Burning The fine powdered raw meal or kiln feed are fed to the 5-stage pre-heater and kiln. Here, the clinkering process happens: Temperature 70 – 100°C 100 – 750°C 750 – 1000°C 1000 – 1500°C
Process Drying Pre-heating Calcination Clinkering
Packing & Distribution
through the roller press for pre-grinding before going into the tube mill for further fine grinding. The ground material then goes through a separation process in the high efficiency separator and is collected by the bag filter. The final product is stored in cement silos.
The finished cement is extracted from the cement silo outlets and transported by screw conveyor and bucket elevator to the packing machine. Portland Cement is supplied in three types of packing – 50-kg bags, jumbo bags and bulk tanker. Masonry Cement is packed in 50-kg bags. For bulk packing,
cement is extracted from the silo outlet through a valve and into a bulk tanker, whilst the jumbo bag packing system is located below the silo. The packed cement is then delivered to customers by road or river transportation.
The main machineries at all plants were supplied and installed by renowned suppliers such as FLSmidth, Polysius, Christian Pfeiffer, Claudius Peter and Haver & Boecker.

CMS Cement has a workforce of over 750 employees. CMS Group has always regarded its employees as invaluable assets that drives the organisation towards its goal. A well-trained workforce improves the competitive advantages of the organisation. In its commitment to build a robust and holistic human capital, initiatives are rolled out such as management trainee development programmes, talent development, Koffee Talks, Town Halls and succession planning programmes. Such initiatives are vital in preparing a ready pool of qualified leaders in the company. Our Work-Life Balance Programme which was rolled out in 2013 aims to provide employees a way to manage their time between the working life and personal life.
PRESERVING THE ENVIRONMENT CMS Cement is committed to minimising adverse impact of its business activities to the environment. The installation of effective pollution control system such as bag filters and electrostatic precipitators are used to control dust emissions so as to maintain below the allowable limit imposed by the authorities. All the production facilities within the CMS Cement have established and implemented the ISO 14001 system to ensure a systematic approach towards its environmental practices. In contributing towards reducing global carbon emission, CMS Cement has initiated a programme for the clinker manufacturing process to partially replace its fossil fuel with alternative fuel, and substituting limestone with alternative raw materials. For the cement grinding process, the consumption of clinker is reduced through replacement with industrial wastes/by-products such as fly ash and slag.
