Stable chemical composition and uniform grain composition are beneficial for calcination. In general retention time of the raw material in the vertical mill is 2-3 mins while the retention time in the ball mill reach 15-20mins. The cement in the vertical mill can quickly measure and revise the chemical composition and fineness.
Jun 01 2016 High pressure grinding rolls roller presses are used in both cement raw materials limestone clay shale etc. and cement grinding stages. The energy consumption is 2.53.5 kW ht and about 10 kW ht when recycling of the material is used.A HPGR consumes 3050 less specific energy as compared to a ball mill which indicates higher comminution efficiency for a HPGR.
Dec 26 2017 According to Bond 1954 the grinding efficiency of a mill depends on the ball mill diameter size of the media and mill speed. Ball mills with different length to diameter ratios for a particular power rating will produce different material retention times. The longer units are used for high retention ratios while shorter units are used where .
Oct 25 2017 The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency a Mill Geometry and Speed Bond 1954 observed grinding efficiency to be a function of ball mill diameter and established empirical relationships for recommended media size and mill speed that take this factor into account.
