Neighbouring the plant is CMSClinker’s own quarrying concessions of key raw materials -limestone, shale and sandstone - covering 78 hectares.Incorporated in 1992, the Company began as SarawakClinker under the Sarawak Economic DevelopmentCorporation (SEDC). Its plant was commissioned in 1996with a production capacity of 2,000 metric tones (MT)per day. This capacity was upgraded in 2004 to 2,400MT per day. In November 2007, the Company which hadsince seen ownership by Indonesian and Filipino entities,was acquired by CMS Cement Sdn Bhd, a subsidiary ofMalaysian public-listed conglomerate Cahya Mata SarawakBerhad (CMS). January 2008 marked a new beginning forthe Company when it changed its name to CMS Clinker.Its current production capacity is 2,500 MT per day orup to 800,000 MT per annum. CMS Clinker is the solemanufacturer of clinker in East Malaysia.How We WorkWe aim to realize our Vision by ensuring that our clinkermanufacturing process attains the following:• Quality Products & Services• Conservation of the Environment• Incorporation of best practices in Occupational Health& Safety (OHS)• Compliance with environmental, OHS and otherlegislations & regulations• Compliance with the requirements of QMS, EMS andOHSMS, and continuously improving their effectivenessWe firmly believe these can be achieved through:• Producing consistent quality clinker• Identifying, satisfying & exceeding our customer’s needs• Minimizing material waste & wastage• Reducing dust & noise emissions• Eliminating / mitigating causes of accidents &occupational disease• Nurturing & instilling safety awareness amongst ouremployeesOur Facilities• Limestone, Shale & Sandstoneconcessions in the vicinity of the Plant• Limestone crusher plant• Combined storage hall• Boom stacker• Reclaimer• Raw Mill• Coal Mill• Kiln• Grate cooler• Silos (2 X 2500 MT and 1 X 15,000 MTcapacity)• A cost effective underground watercooling system, complete with a 33 kVPDS sub-station & fire hydrants• Philips XRF Spectrometer & PARRBomb Calorimeter to monitor rawmaterials, fuel & product qualityProduct SpecsSiO 2= min 21.50 %Fe 2O 3= max 4.00 %AI 2O 3= max 6.00 %CaO = min 65.00 %MgO = max 3.00 %SO 3= max 0.90 %LOI = max 1.00 %Na 2O = max 0.40 %K 2O = max 0.70 %CMS CLINKERCMS CLINKER SDN BHD (Co.

How is CLINKERmanufactured?Raw MaterialGrindingStep 1: QuarryingLimestone, shale and sandstoneform the main raw materialsto manufacture clinker. ForCMS Clinker, all three materialsare quarried within its plant atMambong, ensuring a continuoussupply of quality raw materials.Step 2: Crushing &Storage of Raw MaterialsDifferent crushers are used forthe three raw materials to obtainaggregates of less than 25 mmin size - limestone is crushedby a hammer crusher, shale isput through a roller crusher andsandstone is crushed by an impactcrusher. The resulting crushedmaterials are then stored in silosand storage halls.BurningStep 3: Mixing &Pre-HomogenisingProductLimestone (making up 78% of theraw material), shale (12%) andsandstone (10%) are mixed togetherand pre-homogenised using a boomstacker. This process results in rawmix. A reclaimer is then used totransfer this raw mix onto a conveyorto storage.Step 4: Pre-Grinding &GrindingThis next step involves a furtherreduction in size of the raw mix,limestone and iron ore components.These raw materials are ground witha hammer mill and two other ballmills to achieve an 82% passingrate through a 75 micron sieve. Theresulting fine raw meal powder isthen blended in the blending siloand pumped to a pre-heater. Thecoal used as fuel for the furnace isalso ground using a ball mill to a finepowder called kiln feed which hasan 80% passing rate through a 90micron sieve.Step 5:Pre-heating & BurningThe fine powdered raw meal andkiln feed are fed to the 5-stagepre-heater and kiln. Here, theclinkering process happens:Temperature Process70 – 100 o C Drying100 – 750 o C Pre-heating750 - 1000 o C Calcination1000-1500 o C ClinkeringStep 6: Cooling & StoringFrom the kiln, the hot clinker iscooled to a temperature of 120 0 Cat the grate cooler which usesseven cooling fans. The clinker isfurther crushed to smaller balls ofless than 25 mm diameter in sizeusing a hammer crusher beforebeing transferred using the bucketconveyor system to the clinker silo.Step 7: DeliveryCMS Clinker has the capacity todeliver 2,500 MT per day of clinker.FROM SHALE & SANDSTONE QUARRYTAILINGSEPARATORFROM COAL QUARRYFINESSEPARATORRAW GRINDING MILLTO ROTARY DRYER(NOT IN USE)CYCLONESEPARATORRAW HAMMER MILLCOALCYCLONESEPARATORIRONORESTATICSEPARATORUNCRUSHEDSHALECRUSHEDSHALEUNCRUSHEDSANDSTONECRUSHEDSANDSTONEFINESSEPARATORTAILINGSEPARATORRAW GRINDING MILLCLINKERPROCESS FLOW CHARTRECLAIMERCYCLONEFILTERGCTSTACKERHOMO SILOSCREW CONVEYORFEED BINAERATEDWEIGHTBINSCREW PUMPFEED BINSCREW PUMPC - 1 C - 1C - 2 C - 2C - 3 C - 3EGBINTERMEDIATESILOPREHEATERKILNCLINKER COOLERCOALPULVERIZEDBINCLASSIFIERCOAL MILLCOAL HAMMER MILLCYCLONECOLLECTORCYCLONEHAMMERCRUSHERE.
