summary: the main trends concerning grinding processes in the cement industry are still higher efficiency reduction of the power consumption and system simplicity. in the of new orders vertical mills have increased their share to over 60 % and ball mills have fallen to less than 30 %. it is somewhat surprising that the number of different grinding processes and mill types used by the
the clinker grinding ball mill filling volume is generally 30% to 35% of the mill volume. wet ball mill the filling factor of roughly grinding to 40% of the total volume of the filler as a boundary a high filling rate is greater than 40%. the bulk density of the grinding ball mill grinding efficiency clout larger than the surface area of the

cement vertical roller mill used in clinker production line … vertical roller mill own included the crushing and grinding right into a single whole that have completely satisfied the various specifications from the clients …
however a vertical roller mill for cement grinding generally requires the use of grinding aid to achieve the most efficient operation with a stable grinding bed and a low level of vibrations. vertical roller mills grinding an opc of low fineness say around 3000 cm 2 /g blaine can operate without grinding aid but even when grinding
ball mills that are commonly used for finish grinding have high energy demands consuming up to 30-42 kwh/t clinker depending on the fineness of the cement. complete replacement of ball mills by vertical roller mills vrms with an integral separator as opposed to the use of vrms as pre-grinding to ball mills is regarded as a breakthrough.
there are six grinding systems available for the grinding of clinker . conventional closed circuit system consisting of ball mill bucket elevator and high efficiency separator. pre - grinding with a roller press and subsequent finish grinding in a ball mill operating in either open or close circuit.
