A primary material, limestone, is extracted mainly by bench cut method between the open-air and pitting mine and is then transported to a crusher by truck.
Limestone is stored to maximize homogenized quality after passing the 1st crushing(gyratory crusher) and 2nd crushing(hammer crusher).
This is the process of powdering raw materials into small particles and storing it in silos after mixing limestone, shale, quartzite and irony materials proportionally. When the raw-mix is powdered into small particles and is mixed well, the clinker produced during the burning process is satisfactory.

A core process in cement production is burning raw material. This involves heating up to 900℃ in the preheater and putting it into the kiln to heat it up to 1,450℃. Through this, the raw material is turned into clinker after being fused. Clinker is cooled down to 100℃ passing reciprocating cooling system and stored in the silo.

The clinker in the silo is mixed together with gypsum and other materials and is grinded in the cement mill to become the finished product, Portland cement.
