In the present scenario, Cement Plants are installed with very big capacities to the tune of 3000 to 7000 TPD. A small variation in raw material quality even for small duration may results in big variation of cement quality. To reduce the variation in cement quality, various efforts are being made right from mining to cement grinding.

Rawmill - Wikipedia

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a …

Kiln Operation Procedure - Cement Manufacturing Process

Start dust transportation from Kiln/Raw Mill bag filter/EP. Start main bag filter/EP fan at minimum speed and adjust the speed and damper of the fan to achieve natural draft. Increase bag filter/EP fan speed (alternatively damper position) so that a slightly negative pressure (normally – 30 to – 50Pa or according to your plant SOP) is obtained.

Process Fans Used in Cement Industry - Reitz India

Fans in cement industry are heavy duty and perform two basic functions i.e., supply of air or removal of exhaust gases and material handling. There are many process fans that find applications in cement industry such as raw mill fans, induced draft fans, cooling fans, raw mill exhaust fans, coal mill fans and cooler exhaust fans.

Cement Industry - an overview | ScienceDirect Topics

To make cement, the clinker must first be cooled. Prior to being crushed in the cement mill, the gypsum produced in the kiln is separated from the main product stream. The output from the cement mill may be blended with other constituents to meet certain specifications depending on the end use. The packaged product is then shipped to the consumers.

Purpose of this fan is totransferthe coal powder,the rugged and anti wear design is for overcome the high. dust working condition and pressure shock.

The purpose of a cooler is, obviously, to cool the clinker. This is important for a several reasons: From an engineering viewpoint, cooling is necessary to prevent damage to clinker handling equipment such as conveyors. From both a process and chemical viewpoint, it is beneficial to minimise clinker temperature as it enters the cement mill.
