IELTS PART 1- CEMENT PROCESS
The diagram illustrates how to produce cement with combining all of the materials and how this cement needed in for the building purposes. Overall, it is important to bear in mind that the process to product cement needs some complex processes and the concentrate production combines four different materials.
To begin with, the first diagram reveals that, the clay and limestone are rushed before the powder, the result of first step, passed through a mixer. Next, the produced power passed through rotating heater. Before producing a raw cement materials, the powder has already heated passed on a grinder machine to become raw cement. Ultimately, the cement is packed and ready to be delivered.
The second diagram shows how much the materials needed for producing a concentrate. First of all, it is needed a cement (15%), water (10%), sand (25%), and plenty of small stones (50%). Next, all of the materials are mixed in a concentrate mixer machine. By the time, the machine rotates to overwhelmingly combine all of the materials to create a concentrate for building construction.
