Grinding clinker to finished cement consumes more energy than any other comminution process. world production of cement in was million tonnes and the energy required for comminution was 40-60 kwh/tonne depending on the clinker characteristics and the fineness of the finished cement. machines used include single and multi compartment ball mills, hpgrs, vertical roller mills.
In the manufacturing of cement, clinker grinding is an important process in obtaining a high quality product. as the main requirement is to obtain a consistent fineness of the ground clinker, there are important factors to be considered such as, for example, the feed rate of clinker into the finish mill in an open circuit system, the addition.
It can not only grind cement clinker but also process cement admixture, such as gypsum, fly ash, furnace slag, coal gangue, etc., realizing a stable, high-quality and automated cement production. unlike the cement production line , the cement grinding plant is usually established around the sales market, which saves a lot of transportation.
