参考发文
The process diagram illustrates the steps involved in the production of
bricks that are normally utilized in constructing various structures like houses
and buildings. The entire process mainly consists of four different steps.
First of all, the soft clay is dug from the ground with the help of a
manually operated digger. This clay is then sifted through a metal grid onto a
roller to get rid of rocks and debris. After that, water and sand is mixed with
clay, and bricks are formed by placing the mixture in molds or by cutting them
with a wire cutter. Next, the bricks are dried in an oven for 24-48 hours,
before baking them in a kiln, first at moderate temperature of 200-980C followed
by extremely high temperature of 870-1300C. They are further cooled for 48-72
hours in the cooling chamber, and are later packed and loaded in trucks, thus,
preparing them for delivery to different places.
