Where the alkali occurs in the cement can affect this, but to get a first approximation, we need to track the equivalent alkali content. If a change is noted in the mill certificate, air-entraining agent dosages may need adjustment.

Recently, the vertical roller mill having great grinding performance is widely applied to the raw material grinding process. However, tube mill, which has about 30% poor grinding performance as power consumption, has been still used many existing cement plant. The improvement of this tube mill grinding system is highly expected. DescriptionsProduction capacity: 75±10t/h (Closed circuit, ordinary carbonate cement, specific surface area: ≥320m2/Kg) feeding size≤5mm, moisture≤0.5%, air speed in mill ≥0.5m/s. Mill rotary speed: 15.8±0.1r/min. Charging capacity of grinding medium: 230 ton. The raw material for cement production has a high abrasion rate.

Raw mills usually operate at 72-74% critical speed and cement mills at 74-76%. 3.2 Calculation of the Critical Mill Speed: G: weight of a grinding ball in kg. w: Angular velocity of the mill tube in radial/second. w = 2*3.14*(n/60) Di: inside mill diameter in meter (effective mill diameter). n: Revolution per minute in rpm.


A 1.5 mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance in-terms of system availability and output, however power consumption was on higher side. 3.1 System Description Mill Rated capacity 150 t/h OPC at …The working principle is that cement is removed from the mill before over-grinding has taken place. The cement is then separated into a fine fraction, which meets finished product requirements, and a coarse fraction which is returned to mill inlet. Recirculation factor, that is, the ratio of mill throughput to fresh feed is up to three.
