2) Wet Process - Feed materials for the wet raw grinding circuit may involve materials stored relatively dry and, in the case of previously processed clay, in "slip" form at perhaps 60% - 70% moisture content. Emissions from the transfer of dry feed components to the mill are normally controlled by low temperature bag-type collectors.

2.2 Production process There are four basic types of cement kiln processes currently in use. They are wet process, semi wet process, semi dry process and dry process. The kiln can be considered as the heart of the plant as it constitutes clearly the most important step in the process of cement manufacturing.

Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.

Homogenization (BLENDING) In preparing raw meal, raw materials like limestone, clay and iron ore are proportioned and fed to raw mill, where these raw materials are ground and well mixed. However, this mixing is not enough to produce clinker of uniform quality. For stable kiln operation and to obtain uniform quality of clinker it is necessary ...

Achieving the high early strength of cement-based materials is a necessary condition for the rapid demolding of prefabricated buildings. In this study, kaolin treated by wet-grinding process was utilized as an accelerator in Portland cement. Wet-grinded kaolin-Portland cement system was designed, and 1–4% wet-grinded kaolin was added.

The wet process of fine grinding is the older process, having been used in Europe prior to the manufacture of cement in the United States . This process is used more often when clay and marl, which are very moist, are included in the composition of the cement . In the wet process, the blended raw materials are moved into ball or tube mills ...

The main factor primarily affecting the cement quality is the variability of the clinker activity [1] which depends on the conditions of the clinker formation, raw meal composition and fineness. A stable raw meal grinding process provides a low variance of the fineness. Figure 1. Flow chart of raw meal production
