The process of making cement starts from the mining of raw materials which become the raw material of cement maker, which is limestone and clay in Baturaja.
The breaking and crushing process will produce fine raw materials.
Refined raw materials are transported to storage (limestone storage and clay storage) and mixed with silica sand and iron sand to make raw meal.
Raw meal will be ground in the raw mill after the drying process and the result is stored into raw material storage silo.
After initial heating in the Preheater, the next process is combustion in the clinic, using coal fuel. The result of this process is called clinker. Once cooled, the clinker is stored in the storage.
Clinker produced by Baturaja Factory is partially milled at Baturaja Plant and partly brought to Palembang and Panjang Factory for further process in both factories.
In the factories, the clinker is milled, and added auxiliary raw materials such as gypsum, before being put into the cement mill.
The result of grinding clinker with gypsum is called Portland Type I cement, ready to be bagged and sold to the market. Semen Baturaja is available in bulk and zak packaging.
