CASE STUDY : LAFARGE Rawang Plant, Malaysia (CS12)


About LAFARGE Malayan Cement

Lafarge Malayan Cement is a manufacturer of building products. The company is organized into two business units: cement and aggregates and concrete.

The company’s cement operations are located in Malaysia and Singapore. In Malaysia, it operates a nationwide network of facilities which include three integrated cement plants in Langkawi, Kanthan, and Rawang, one grinding plant in Pasir Gudang, and distribution channels by road, rail, and sea. In Singapore, the company’s Lafarge Cement Singapore (LCS) subsidiary produces and markets various types of cement including oilwell cement, which is exported to East Asian countries, and a range of dry-mix cement products.

Aggregates and concrete activities take place in Malaysia, Singapore, and Vietnam. In all three countries, the company operates through Supermix, a provider of ready-mixed concrete.

         
 


Silo capacity: 5000 ton

Amount of cement in silo: 2600 tons



 

Lafarge Malayan Cement — Rawang Works had one of its silos blocked for over 2 years and so requested a total cleaning operation….

 

BUT WHY CARDOX?

Reliability & efficiency …
Cardox Tubes produce a pressure of up to 3000 bar!! And by installing specifically designed Sockets to accommodate Cardox Tubes, Cardox strikes right at the heart of the build-up!

Cost savings …
Lafarge knew that unlike other silo clearing methods such as whips, using Cardox meant the silo did NOT have to be shut down and so the old cement was still saleable!

 
         

 

         
   

Schematic view of silo.

 

 

 

The old cement was blocking the air slides as well as bridging preventing the flow of cement from the silo.

 

 

 

Cardox Sockets installed above discharge gates and lower air slides proved the ideal solution to blocking of silo and can be used whenever there is build-ups.

 
         

 

         
 

View of build-up from top of silo.

Build-up stretched virtually all the way up the silo’s 35m height.

 
         
 


Sockets are welded onto discharge  area to accommodate Cardox Tube either side and above Discharge gate where blockage occurs.

 


Plug is removed to reveal blockage above discharge gate.

 
         
 

Cardox Tube inserted into build-up ready to be activated. Tube is directly above air slides.

Discharge chute moments AFTER Cardox Tube is activated.

 
         
 

Many hard lumps were removed from silo after Cardox Tubes were activated.

 
         
     
 

Tankers now being filled with cement. Cement is free flowing again as can be seen by the dust coming from second portholes in tankers.

 
         
 


Silo is completely cleaned.

 

Cardox helped remove 2400 tons of useable material which are loaded into tankers and sold! We effectively saved Lafarge > US$100k by using the Cardox System.

We then proceeded to remove the remaining 200 tons of build-up hard material and cleaned the entire silo.

 
         

 

The Cardox System is both versatile and safe for silo cleaning, clearing of build-up, blockages and rock excavation. It has been proven to many as the most EFFICIENT, RELIABLE and COST EFFECTIVE method used today.

The SiloWhip System is the MOST POWERFUL silo whip in the world. Although it is purposely build to take on the hardened build-up commonly found in cement and clinker silos, it is GENTLE enough to clean out other materials.
