Production of roofing tiles with locally available clay could reduce the cost of houses construction. Although the product is relatively new to the market, it is gaining wide acceptance in a short period of time.
Raw materials
|
The raw clay is exposed to the weather for about a year. This will improve the plasticity of the clay. The weathered clay is then cut and fed
to heavy duty pug mill crusher. The crushed and pugged clay is extruded in the form of blocks and is directed to a wire cutting table.

The blocks are allowed to dry for a few days and the dried stabs are molded with a title press. The molded tiles are dried in a continuous drying kiln. After the furnace is allowed to cool, the tiles will be unloaded for dispatch.
Alternative technological process:
The major processing stages for making roof tiles from clay are preparation of the clay soil (i.e excavation of the soil from the ground, removing “foreign” materials, probably grinding or breaking the soil into finer particles, moving the soil to molding section, adding water to the soil and making it into a “dough”, putting the “dough” into molds, firing the “green” roof tiles in a specially designed “oven”, removing the fired tiles from the “oven”, and finally staking the finished clay.
