If a vertical roller mill is used for raw grinding in cement industry then a large raw mill fan is installed. Usually cement industries use centrifugal fans to carry out this process. 4.
The Cement Manufacturing Process - Advancing Mining
In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement.

Raw Material Preparation - an overview | ScienceDirect Topics
The test process was divided into the raw material preparation stage and the brick-making stage. In the raw material preparation stage, the muck was dried in an oven at 105°C for more than 24 hours; then a grinder was used to crush it to less than 0.25 mm in diameter. In the brick-making stage, the process of making unfired bricks can be divided into the raw material …

cement - Extraction and processing | Britannica
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.

Manufacturing Process – Continental Cement
Raw meal now enters the huge rotating furnace called a kiln. It's the heart of the cement making process—a horizontally sloped steel cylinder, lined with firebrick, turning approximately four revolutions per minute. The kiln is the world's largest piece of moving industrial equipment.
Raw Mill In Cement Plant,Cement Making Plant
A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. It's mainly used in grinding raw materials and end products in cement plant. Raw mill is made up of feeder part,discharging part,rotating part,transmission part (reducer,samll transmission gear,motor,electric control) etc.
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 …
