traditionally vertical roller mills operate with feed around 80100 mm size but reducing this to lower size has proven beneficial to capacity enhancement in number of plants; with ball mills the vertical roller mills are the mills traditionally used for process-ing granulated blastfurnace slag and for grinding composite cements. from the energy aspect they are superior to grinding plant circuits with ball mills, even when combined with high-pressure roller presses. for drying and grinding
the ball mill has low energy utilization efficiency.at present, there is a tendency to replace ball mill with vertical mills and roller presses, but the ball mill has the advantage that the particle shape is approximately spherical, which is conducive to raw material calcination and cement hydration hardening.grinding aids for ball mills. cement grinding aid for vertical grinding mill machine water the best grinding aid for vertical cement mill grinding aids are used in the cement mill ball mill vertical roller mill horomill to increase the productivity save electrical energy andor to increase the fineness and improve defined cement properties eg

aug 13, 2015 vertical roller mills are widely used in the concrete and mining fields, and are also used to process coallime and gypsum. these units can process both raw and recycled materials, while helping to reduce waste and preserve virgin supplies of these materials. capacity:the vertical roller mill adopts dynamic powder selecting device, which comes with high powder-selecting efficiency and convenient adjustment of fineness. after crushed by crusher, the large materials become small ones and are sent to storage hopper by elevator, and then evenly sent to the upper distribution plate of the turn plate by vibrating
applications of the vertical roller mill for cement grinding are less prevalent. the two-compartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding installations although the vertical roller mill now has emerged as a viable alternative to the ball mill system and has increased its share of the market for cement mills the first introduction of a positively acting mixture for mills were grinding aids. per cent for ball mills and from per cent for vertical roller mills. grinding clinker replacement materials re
vertical cement mills are able to reach production values which are significantly higher than the ones achievable with traditional ball mills, in some cases up to 300 th. empirically, It can be estimated through a simple heat balance that in ball mills only 10% of the energy is used to increase cement fineness, the rest being dissipated basically in form of heat.
