IELTS Academic Task 1: Process Diagram — Industry & manufacturing
Original practice prompt written in exam style — not a real exam question, and not a prediction.
The diagram below shows the process of making bricks for the building industry. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. The process is as follows. First, clay is dug from the ground by a large digger and placed on a metal grid, where it is broken into smaller pieces that fall onto a roller. Next, sand and water are added and the mixture is either pushed through a wire cutter or placed into moulds to form the brick shapes. The bricks are then dried in a drying oven for 24 to 48 hours. After drying, they are baked in a kiln, first at a moderate temperature of 200–980°C and then in a second kiln at a high temperature of 870–1,300°C. Finally, the bricks are cooled in a cooling chamber for 48 to 72 hours before being packed and delivered to customers.
Examiner focus: Seven stages from raw clay to delivery: the middle of the answer should contrast the drying, firing and cooling times and temperatures.
