Progress with Grinding Aids for Vertical Roller Mills
The differential pressure between the inlet and outlet of the mill (ΔP mill) is an important process variable for the testing of grinding aidsΔP mill reflects the load and the filling level of the mill At unchanged separator settings, the increase of ΔP mill indicates more internal circulations and more fines As a result of the higher ΔP mill, the mill vibration increases (810mm/s There is an optimum stress intensity range for a particular material and feed and product size where maximum grinding efficiency is achieved Optimum stress intensity should be used for the selection of appropriate mill type and scaleup Pilot vertical pin stirred mill was more energy efficient for grinding an calcium carMedia stress intensity analysis for vertical stirred mills If we instead focus on wet grinding, we should differentiate between stirred media grinding, which can be both vertical and horizontal, and tumbling mills with manufactured grinding bodies A continuous gratedischarge tumbling mill with grinding balls does seldom have ball size below 20 mm since you then will have unacceptable media losses or Vertimill VS Ball Mill Grinding Classification
