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 large effect upon the ...
In a cement plant, the air flow to a raw mill is monitored. The objective of this monitoring is to achieve the highest possible efficiency of the raw mill. Controlling the supply air to such a vertical mill can also lead to considerable energy savings, as the maximum air volume does not always have to be used, but can be adapted to the process.
Cement Separator. Cement separator, also called cement mill separator, is the necessary equipment in the powder classifying system of cement, chemical, mineral, and other industries. It can respectively collect the qualified fine powder and coarse powder from the airflow after they are ground by the grinding equipment to a certain extent.

A raw mill fan is located between the cyclone separator and the bag filter. The circuit will be designed to allow gas re-circulation from the raw mill fan back to the inlet of the mill. The duct of the mill inlet is to be equipped with a fresh air intake in order to adjust the mill inlet temperature.

After separation by the cyclone, the raw meal passes out through a one-way valve which prevents hot gas from coming up the feed pipe. The more stages are used, the more efficient the preheater is. But each stage increases the pressure drop across which the kiln fan must work, and with more than six stages, the fan power requirement is prohibitive.
Hey; Our plant is an offline PC kiln with 5 stages preheater and bypass system. Last week a big explosion happened in our preheater riser duct towards Cyclone-5. The results of this explosion are: 1- Riser duct towards cyclone-5 damaged completely (Bricks and castable pieces found 1000 meter far from the preheater)

Aug 31, 2020· 31 Aug, 2020, 11:30 am. Use of alternate fuels in the Cement Kiln leads to excessive preheater exit temperatures. The Cement plant in Jakarta, Indonesia with a capacity of 7800 TPD, planned extensive use of alternate fuels in the kiln. This was leading to excessive Preheater exit temperatures up to 4300C and was limiting the fan capacity.
A multi-stage cement calcining plant suspension preheater has a calcining combustor flow connected with a cyclone separator in the uppermost stage and helical duct inertial separators in the remaining stages which are lower in height and in pressure drop than conventional cyclone separators and permit reduction in height of the preheater tower and use of a lower horsepower fan to move kiln-off ...

Cyclone preheaters are also called suspension preheaters. In the new dry process of cement manufacturing, the raw meal must be preheated in the preheater before entering the rotary kiln for calcining.The quality of the preheater in a cement plant directly affects the stability of calcining temperature and cement clinker quality in the kiln.

For cement plants, maximizing machinery reliability and availability is one of the key ways to positively impact profits. Because cement plants operate continuously for long periods of time, unexpected failures from electrical equipment such as a Raw Mill Cyclone Fan will require the whole cement plant to shut down resulting in expensive repairs or a replacement, as well as multi-day downtime.
Raw meal enters (at 50 0 C) in the riser duct of second cyclone (from top) and is picked up with the hot gases to first (top) cyclone, where raw meal is separated from gas stream and passed down to second cyclone. Heat transfer takes place in suspension phase between hot gases and raw meal.
