1st Phase Ingredient Processing


In this phase, basic brick raw material / ingredients such as clay, yellow soil, Koryong-to etc are ground, and mixed to suit each individual product characteristics such as clay brick, yellow brick and paving block
Raw material/ingredient	Each raw material supplied from the Quarry is processed to ground.

Sifting	Other particles and big stones are shifted and removed.

Flat mill	raw material is further ground and mixed, using water

1st grinding	Already ground raw material is again ground to the size of 1.2 ~ 1.5 mm

Silo	Ground and mixed raw material is stored to mature for 2 weeks. This process ensures even and consistent distribution of water within raw material.

Final sifting	Matured raw material is again more finely sifted and mixed to achieve optimum mixing ratio.

Optimum maxing ratio	After the final sifting, raw material is mixed in optimum ratio.

2nd grinding	Using grinder space set at 0.8mm (or below), matured and resifted raw material is very finely ground again, enabling the raw material to be ground to the size of 1mm, or less. This process is essential in achieving good quality product surface, thus improving the entire product quality to next level.
