At cement plant, according to different raw materials preparation methods, cement manufacturing can be divided into the dry process (including semidry process) and wet process (including semiwet process). next, we will discuss the wet process of cement manufacturing in details.

Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 c in a cement kiln. in this process, the chemical bonds of the raw materials are broken down and then they are.

Example – manufacturing process of cement. cement is considered as a product which is a result of unit operation and unit process. there are various unit operations and unit processes are involved in the manufacturing process of cement. we will not go indepth into the manufacturing process and will consider the relevant things only.

Cement manufacturing process phase 1: raw material extraction. cement uses raw materials that cover calcium, silicon, iron and aluminum. such raw materials are limestone, clay and sand. limestone is for calcium. it is combined with much smaller proportions of sand and clay. sand amp; clay fulfill the need of silicon, iron and aluminum.

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.

Cement is kept in clicker (intermediate product of the cement manufacturing process) and then grinded as orders appear. second, packtoorder, where cement is kept in bulk and then packed as orders appear. further research should be made to confirm the feasibility of these alternatives.

Cement is so fine that 1 pound of cement contains 150 billion grains. the cement is now ready for transport to readymix concrete companies to be used in a variety of construction projects. although the dry process is the most modern and popular way to manufacture cement, some kilns in the united states use a wet process.

Manufacturing the cement kiln. most portland cement is made in a rotary kiln. basically, this is a long cylinder rotating about its axis once every minute or two. the axis is inclined at a slight angle, the end with the burner being lower. the rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the.

The diagram provides information about the different levels and tools required in the production of cement, and how cement contributes to the making of concrete for construction purposes. overall, the manufacturing of cement requires a dry process, while concrete production on the other hand is a wet method.

Cement storage amp; distribution • at this point the manufacturing process is complete and the cement is ready to be bagged or transported in bulk away from the plant after the grinding process, cement is pumped into the storage silos. • this silo is preventing the moisture to react with cement.
