Aggregates and cement should be ordered in good time. Stocks should be suffi cient to prevent stoppages due to lack of material. As a rough guide, using aggregate cement ratio of 8:1 by loose volume, three and a half bags of cement and a cubic metre of aggregate will be enough to make about 400 standard bricks.

After crushing, the raw materials are transported to the plant by conveyor. Before homogenized, the plant stores the material. Too finely ground, the materials are transferred to the raw mill, to produce raw mix. The raw mix is preheated before it goes into the kiln, and by the flame, it can be heated to 2000 °c to produce clinker.
