The diagrams below show the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes. Sample answer 1:- The given both process charts illustrate the steps and material which are used to make cement and how is concrete is produced for the construction of the building.
AGICO provides EPC turnkey projects and various professional equipment for cement production line, stone crushing plant, cement grinding unit, fly ash processing plant, and VSK cement plant. In addition, we also offer the cement plant upgrade and retrofit service according to customers’ specific needs.
Cement Cement Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.

Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.
Equipment for pyroprocessing includes kilns, electric arc furnaces and reverberatory furnaces. Cement manufacturing is a very common example of pyroprocessing. The raw material mix is fed to a kiln where pyroprocessing takes place. As with most industries, pyroprocessing is the most energy-intensive part of the industrial process.
12/29/2017· Cement concrete is a major building material in the world which is widely using because of its marvelous structural properties. The ingredients of cement concrete are cement, fine aggregate, coarse aggregate and water respectively. In general, ordinary Portland cement is used to
The first step in cement production is to introduce limestone and clay. These materials pass through a crusher that produces a powder then, this powder goes into a mixture. After this, the product passes to a rotating heater which works with heat. Next step, the mixture goes into a grinder where the cement
7/28/2020· In the cement production diagram, firstly, limestone and clay are gathered and passed through a crusher. Then, the powder obtained from crusher is moved to the mixer to make a homogene mixture. Next, rotating heater welcomes the material from the mixer.
10/22/2015· Rotary Kiln Kiln is cylindrical rotary equipment rotating on supporting rollers. Due to the inclination of the cylinder and slow rotation of the material, the materials roll in hoop direction. On the other hand, the materials move from the high end to the low end, where they are decomposed, burnt, cooled in succession.
At the first stage, limestone and clay are crushed through crusher machine and changed to powder. These powders are mixed together by mixer and gone into rotating heater which works with heat. After that these materials are gone into grinder and changed to cement which are packed to bags.
While the use of cement in concrete has a very long history ( Malinowsky, 1991 ), the industrial production of cements started in the middle of the 19 th century, first with shaft kilns, which were later replaced by rotary kilns as standard equipment worldwide.
Pyroprocessing includes such terms as ore-roasting, calcination and sintering. Equipment for pyroprocessing includes kilns, electric arc furnaces and reverberatory furnaces. Cement manufacturing is a very common example of pyroprocessing. The raw material mix (raw meal) is fed to a kiln where pyroprocessing takes place.
The most common raw rock types used in cement production are: Limestone (supplies the bulk of the lime) Clay, marl or shale (supplies the bulk of the silica, alumina and ferric oxide) Other supplementary materials such as sand, fly ash/pulverised fuel ash (PFA),
Cement concrete pipes are widely used as drains, pipes under culverts etc. Cement concrete brick masonry is more famous because of the size of block, ease of construction and strength etc. Water tanks and septic tanks are generally constructed by cement concrete rings.
Other plastic waste segregated from electrical and electronic equipments can also be transported to nearest cement plant for co-processing. Thus all segregated combustible fraction can be transported to nearest cement plant as alternative fuels or raw material (AFR).
Food processing equipment used during this process are Sieves/Screens (Size sorting) Sorting Machinery; Machine Vision Sorting Systems; Sorting Conveyors; Disc Separators (Shape sorting) Equipment used in dry process in cleaning. B) MECHANICAL PROCESSING EQUIPMENT
