RSK Brick Manufacturing Unit in located near Chinnathadagam village in Coimbatore district. Our Polytechnic College second year Civil Engineering students and Staff members visited the brick manufacturing unit at 11.45 PM by College bus.
The Various Processes are involved in the manufacturing of bricks,
Fine sand and soil materials are used as raw materials for the Preparation of Clay. Sometimes the brick earth is collected from outside the Manufacturing unit.
The manufacturing unit has Plastic clay machine which uses wire cut brick moulding method. The bricks are cut by wire and spacing between two wires equal to the thickness of bricks. 35,000 bricks are manufactured per day.
Brick unit consists of arranging the wet bricks in many rows on their edges. A little space for circulation of air is kept for each brick. A portable temporary place is provided to protect the bricks from rain. Drying duration for the bricks is taken 2 to 5 days. It is mainly depending upon the weathering agencies.
We saw the place where the bricks were burnt, the chimney as well as the casting of bricks from the mixture of raw materials.
The aims of burning bricks are as follows
The materials used for burning of bricks are coal, lignite as well as waste materials of paddy and groundnuts. The sand they used for particular type which was suitable for a brick. First of all the raw materials were mixed in proportions, kept in front of sun for drying for two days and then applying for burning at 500 degree Celsius for 2 days and then kept for cooling for about 15 days. Functions of each chamber contains loading, during, preheating, burning, cooling and unloading at the same time. There were around 100 skilled workers in company.
This visit was really useful for learning practical knowledge and informative for Civil Engineering team to know about manufacturing of bricks and a large scale industrial planning.
