Academic Writing Task 1 #23 Process and Cycle – Bricks Manufactured

You should spend about 20 minutes on this task.

The diagram below shows the process by which bricks are manufactured for the building industry.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Write at least 150 words.



The picture illustrates how bricks are produced.

The process begins when clay is dug out through the use of a digger, which is followed by clay passing through a metal grid. Fine clay is then carried by a roller after which sand and water are added to it. In the next stage, either this mixture is pressed through a frame and cut into bricks using a wire cutter, or it is put into moulds and formed into bricks. Following that, the bricks are dried in a drying oven for one to two days. The next three stages involve two kilns connected to a cooling chamber. The dried bricks are first heated from 200 to 980 degrees centigrade, before being exposed to high temperature (870 to 1300 degrees). They are then cooled within 48 to 72 hours. Eventually, they are packed and delivered to customers by trucks.

Overall, the procedure of producing bricks is comprised of ten stages which are rather simple.

The picture illustrates the procedure for producing construction bricks from clay, sand and water through ten rather simple stages.

It commences when raw clay is dug using a digger machine following which it is sifted through a metal grid into finer fragments which then fall onto a conveyor belt. In the next stage, water and sand are added and the resulting mixture is either pushed through a frame and cut into simple bricks, or is moulded into specially-formed bricks.

These are then placed in a special oven for one or two days in order to minimise their moisture content. The following three stages involve the use of a couple of kilns and a cooling chamber: bricks are first heated moderately in the first kiln to reach a temperature of between 200 and 980 degrees centigrade before being subjected to higher temperatures (870 to 1300 degrees) in the second one. Next, they are allowed to cool down for two to three days in the cooling chamber. The process ends with the bricks being packed on pallets and delivered to end users on trucks.
