 Writing task 1 Sample 54 - bricks manufacturing process

Sample Answer 1:
The given diagram shows different stages of brick manufacturing for the building industries. Generally speaking, brick production involves 7 steps, starting from the digging stages and ending at the delivery stage.

As is given in the graph, the first step of brick manufacturing is digging the clay with a large digger. This clay is then filtered and processed in a roller machine and then mixed with sand and water. In the third stage, the mixture is either kept in a mould or cut in a wire cutter to make the raw shape of the bricks. In the next step, the shaped raw bricks are dried for 24 to 48 hours in a drying oven. After that, the dried raw bricks are kept in a kiln, both in moderate and high temperature, up to 1300 degree centigrade and then placed in a cooling chamber for about 48 to 72 hours. This process makes the brick to be packed and delivered in the final two steps. The delivery process is the final process of brick manufacturing and as it is noted, brick making is a moderately complex process that requires some predefined works to make it usable.

Model Answer 2:
The diagram gives information about the manufacturing process of construction bricks. Overall, brick manufacturing requires some controlled stages and complex equipment.

To begin with, the clay is collected by a digger machine and then the clay is passed through a metal grid to grind them. The smashed clays are transported to a roller and sand and water are mixed with this. The mixture later either moves through a brick cutter, which shape of bricks, or is placed into a mould in which the shape of a brick is formed. Afterwards, these brick-shaped parts are put into a drying oven and stay there for 24 to 48 hours. Next, they are transferred to the first kiln for heating, whose temperature is moderate, 200 to 980 C. After this, they are heated in the second kiln under the high temperature from 870-1300C. Subsequently, in a cooling chamber, they are cooled for two to three days before they are packaged and delivered to the construction sites.

To summarise, the whole process consists of generally seven steps during which the raw material is dried, heated, cooled and packaged.

Sample Answer 3:
The diagram illustrates the brick manufacturing process in an orderly manner starting from the digging of clay. As is seen in the given illustration, brick manufacturing is a complex process and involves 7 stages until they are ready to be sold in the market.

The process is initiated by digging clay with the help of a heavy machinery digger. This clay is then refined through the metal grid which throws the refined clay on the rollers. Sand and water are mixed and this mixture is either moulded or cut using a wire cutter to give the bricks a raw shape. These bricks are put in a drying oven for one to two days. The dried bricks are then passed to kilns with moderate (200 to 980 degree C) and high temperature (870 to 1300 degree C) and finally placed in a cooling chamber for 48-72 hours. After cooling down the bricks, they are placed on a pallet for packaging and to be loaded on a lorry for delivery.

In conclusion, the process of manufacturing bricks is a complex process which passes through several stages before the bricks are ready to be used.

The diagram describes the brick-making processes. It is obvious that making bricks is a long and complex process that follows several steps - starting from the large clay digger machine stage and ending by the package and delivery stage.

Once the sticky earth is collected and separated from the soil, the clay is moved immediately to the metal grid which turns it into brick-manufacturing raw material. It is sent through the roller to be mixed later with sand and water and dropped to two different brick makers which are the wire cutter and the mould.

Once ready, both two brick types are transferred to the drying oven which takes between 24 to 48 hours to be completed so that it can be sent to the kiln steps. Firstly, the clay is fired in a moderate kiln with a temperature between 200°C and 980°C then it goes automatically to a higher temperature kiln with over than 870°C to a maximum of 1300°C. Then finally, they are transferred to the cooling chamber which takes between 48 and 72 hours to end the operation. After being packaged the bricks are ready to be placed in transport then delivered to building industries.

The diagram illustrates the procedure for the production of bricks for construction purposes.

Overall, it can be seen that it requires a sophisticated process for manufacturing bricks, which consists of 7 stages, starting with the digging of clay and ending with the packaging and delivery. Moreover, several instruments, such as roller, drying oven, kiln and cooling chamber are needed for this.

The process begins when the clay is dug by a digger and is passed through a metal grid, which converts it into finer fragments. When this stage is completed, the fragments are carried by a roller before adding water and sand to it. Afterwards, this mixture can be transformed into bricks either by using a wire cutter or by putting into a mould to give this the shape of bricks.

The next stage starts by transferring the delicate and fragile bricks into drying oven where it is dried for 24 to 48 hours. This is followed by shifting of the bricks to moderate temperature kiln (200-980°C) and high-temperature kiln (870-1300°C), respectively. After completion of subjecting the bricks to a high-temperature kiln, they undergo cooling for 48-72 hours in the cooling chamber, following which they are packaged. The last stage is when they are delivered by a truck for further construction purposes.

The given diagram depicts the different steps involved in the brick manufacturing process. Overall, brick production comprises seven stages, starting from the digging stage and ending in the delivery stage. First, the clay is dug out by a large digger machine, which put the clay over a metal grid to remove rocks and other particles. Then, with the help of a roller machine, the clay is mashed carefully to obtain a fine powder, which is subsequently mixed with sand and water. At this point, the brick manufacturer has two options to make rectangular clay bricks: the wire cutter or the mould. Once the raw bricks are shaped, they are carried into a drying oven where they remain between 24 - 48 hours. After that, they are kept in a kiln, undergoing temperatures from high to moderate, reaching up to 1300 degree centigrade, and then are placed in a cooling chamber for around 48 - 72 hours. Finally, the bricks are packed and are ready to be delivered.

Fantastic, Mentor.
The diagram illustrates the process involved in brick production before they can be used for building purposes. Overall, we can see that after the clay has been mixed with water and sand, it is passed through many stages before bricks are being packaged and ready for delivery. In the first three stages, clay is being collected by a digger and then refined on a metal grid which eliminates the big pieces before being processed on a roller. The clay is then mixed with sand and water. The resulting mixture is either put inside a mould or passed through a wire cutter to form the square shape.The next stage is collecting all the bricks and they are then sent to a drying oven and kept there for 24-48 hours. After that, they are transferred to two kilns, one has a moderate temperature (200 -980 degree C) and the other has a higher temperature (870 -1300 degree C). Later, the hot bricks are stored in a cooling chamber for 48-72 hours. The final stage involves the packaging of the bricks and they are then ready for use.
Present continuous, passive and present perfect are not common when it comes to describing a process.
Hello. Thank you very much. Your lessons help me a lot and I need more solutions on Flow Charts. Thanks again :-)
