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 case 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
Our designers are constantly coming up with new ideas and even more dependable components to reduce the already acclaimed low failure rate of our mills the roller grinding mill technology patented in 1928 and continuously developed since then has become synonymous with loesches pioneering engineering knowhow
Recently especially from 1980s grinding system using the vertical roller mill which has effective grinding performance is developed and applied in the cement grinding process descriptions basic equipment structure of the vertical roller mill for cement grinding is the same as the vertical roller mill of raw material and coal grindings
Grmk vertical cement mill has the advantages of compact structure and small volume it mainly includes high efficiency separator grinding rollers grinding table hydraulic loading device of grinding roller hydraulic lubrication system reducer motor and electrical components 1 separator is an efficient and energysaving powder selection
Cement grinding the clinker from the pyroprocessing area is ground in ball mills or roll press ball mill combination or vertical roller mills to form cement commonly used separators are in closed circuit grinding are o sepa sepol and sepax separators to achieve a finish cement fineness of 3000 4000 blaine surface cm2gm
Fig2 schematic process flow of vertical roller mill for grinding of raw materials vertical roller mills are adopted in 20 cement plants 44 mills in japan results table energy saving effect of the vertical roller mill ball mill specific power cost estimation
As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions they give cement plant owners a great opportunity to maximise productivity and minimise operating costs the high energy efficiency is especially beneficial in regions with limited power generating capacity or where electricity availability is limited
Ball mill ball mills with high efficiency separators have been used for raw material and cement grinding in cement plants all these years ball mill is a cylinder rotating at about 7080 of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills
Cement mill wikipedia most cement is currently ground in ball mills and also vertical roller fine grinding lessens this effect and early cements had to be stored for
After the combined cement grinding system of 48m 95m ball mill and roller press is put into production the output of the system is low and the energy consumption of cement unit products is very high and the comprehensive power consumption per ton of cement is more than 38 kilowatt hours
