Band 6+: The diagrams below show the process of preparing raw materials for ceramic tiles, and the steps involved in manufacturing them. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The given picture demonstrates how ceramic tiles are manufactured.

Overall, the linear process comprises two specific stages including pre-preparation and processing.

Beginning first with the preparation of raw materials, initially, clay is hamonically combined with fresh water. This mixture, following that, is ground intensively in order to create moist slurry. Afterwards, filter machinery is employed to tightly press slurry until its moisture is completely eradicated. Dried slurry is then conveyed into spray dryer, where it is desicated to dried powder. Thereafter, the powder is undergone tile press to shape into rectengular pieces, ready for the next stage.

Once the preparation stage is complete, ceramic pieces are transformed to chamber, where they are dried artifically in high temparature, especially 100 to 200 degree, for 1 to 3 consecutive days so that they can be kept for a longer period. The process continues with an automated conveyor belt, with each piece being sealed with a coating and being got through glazing machine. Subsequently, the kiln is utilized to dry once again, albiet to a powerful extent,particularly 1000 to 1250 degree, in 20 to minutes before completing finished products.
