Dear teacher, could you give me some comments on this task?

The diagram illustrates the process that is used to manufacture bricks for the building industry.
Summarize the information by selecting and reporting the main features and make comparisons where relevant.
Write at least 150 words.

Here is the diagram (I dont know how to copy the image directly so I only could copy the link)

The flow chart depicts the process of brick production in construction industry. Overall, there are seven main stages in this process, beginning with clay excavation and culminating in transportation of products to potential customers.

Firstly, clays are dug up from the ground by a large excavator. Subsequently, with the assistance of a roller, raw clays are broken into small pieces via a metal grid. Afterward, the mixture of clays, sand and water is poured into a mould or a wire cutter, which will help shape the bricks rectangular and evenly.

In the following stage, wet bricks go through dehydration process. Here, an oven will be utilized to dry bricks within one to three days. Once being dehydrated, those bricks are fired in a special kiln at temperatures ranging from moderately 200^oC up to 1300^oC. The immediate products are then cooled down by a chamber in the period of three or four days before being packaged. The entire process concludes after the finished bricks are transported to merchants and ready to be purchased.
