IELTS Diagram: Model Answer Band Score 9

2 天前  The flow chart illustrates the process of making cement, while the other diagram shows how different materials are combined with the product to produce concrete. Overall, cement manufacturing takes four steps, beginning with crushing and ending with cement in bags.

Iron Ore Pelletizing Process: An Overview IntechOpen

2017-7-10  The straight grate process is composed of a single furnace where an endless line of pallet cars moves. A layer of indurated pellets is arranged at the bottom of each car to protect it against the heat. The green pellets are then charged on top of the hearth of indurated pellets. A schematic diagram of this process is shown in Figure 7.

Carbon Cycle Definition, Process, Diagram Of

Carbon Cycle can be classified into two types based on the duration of the process into two types: Short term This type occurs within a relatively short period of time. It is named as such because it takes just days, months or years for carbon to flow across the various carbon reservoirs. Long term This type takes thousands of years to

Solvay process Wikipedia

2021-4-10  The Solvay process or ammonia-soda process is the major industrial process for the production of sodium carbonate (soda ash, Na 2 CO 3).The ammonia-soda process was developed into its modern form by the Belgian chemist Ernest Solvay during the 1860s. The ingredients for this are readily available and inexpensive: salt brine (from inland sources or from the sea) and limestone (from

Graph Writing # 102 Stages and equipment used in

The two diagrams illustrate the cement-making process. We can see from the given illustration that cement is manufactured first, and then it's used in the concrete production. In the first diagram, we can see that limestone is the raw material with which clay added. Firstly, the two materials are crushed to form the powder.

Flexible Screw Conveyors Convey in Any Direction

The steel tube of the smaller conveyor is located within the spiral of the other. As the diagram shows, the tube of the smaller conveyor extends beyond the inlet hopper of the larger conveyor. This ensures that the flow of the minor ingredient is introduced into the primary one at

Manufacturing of Portland Cement Process and

2021-4-19  The Fig.1. show the flow diagram of the dry process of the manufacture of cement. 1. Dry Process. In the dry and semi-dry process the raw materials are crushed in a dry state. Then, they are processed in grinding mill, dried and reduced to very fine powder-like. That dry power is further blended, corrected for the right composition and mixed

12.5 Iron And Steel Production

2015-9-10  12.5.1 Process Description1-3 The interrelation of these operations is depicted in a general flow diagram of the iron and steel industry in Figure 12.5-1. Coke production is discussed in detail in Section 12.2 of this publication, and more information on the handling and transport of materials is limestone, mill scale, and flue dust

Concrete: Scientific Principles

2007-8-3  Huge crushers break the blasted limestone into small pieces. The crushed limestone is then mixed with clay (or shale), sand, and iron ore and ground together to form a homogeneous powder. However, this powder is microscopically heterogeneous. (See flowchart.) Figure 1: A flow diagram of Portland Cement production.

Read "Rock Fractures and Fluid Flow: Contemporary

The purpose of this chapter is to provide a geological and geomechanical understanding of fracture formation, characteristics of various fracture types, network patterns, and internal structure.The geometry of fractures, their internal architecture, and present-day state of stress control fluid flow in fractured rocks. A geomechanical understanding of these properties provides an intellectual

Sedimentary rock Wikipedia

2021-4-16  Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or
