Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits …
Compared with the clinker production line with higher construction cost, the clinker grinding plant does not need to purchase the equipment used in a series of expensive clinker production lines such as crusher, cement rotary kiln, coal mill, cement cooler, etc. Relevant production processes are reduced, and the required plant area is also ...

During the 1980s, the technology of vertical roller mills for clinker grinding saw several improvements. Manufacturers like Loesche, FL, and Polysius began to refine the design and operation ...
Clinker is a critical component in the production of cement and forms the intermediate product during the cement manufacturing process. It can be best described as a nodular material, usually grayish in color, which is produced by sintering limestone and alumino-silicate materials such as clay at high temperatures in a cement kiln.
It is used to grind slag, nonmetallic ore, and other block and granular raw materials into the fine powders necessary for production. In the mid-1990s, Loesche developed the VRM technology, which was first used for grinding clinker and slag [3]. Fig. 1 shows the components of a Loesche mill used for grinding.
Nowadays, ball mills are used widely in cement plants to grind clinker and gypsum to produce cement. In this work, the energy and exergy analyses of a cement ball mill (CBM) were performed and some measurements were carried out in an existing CBM in a cement plant to improve the efficiency of the grinding process.
To control setting time, gypsum has to be added to the clinker during the finish-grinding process. Typical portland cement contains approximately 5% of gypsum. At this stage, the production of cement, the binder that holds the sand and the a.ggreg::Hes in the concrete and mortar together, is completed. 1his is the most durable construction ...
