Mar 15, 2015· It is possible to predict the vertical mill product size distributions considering a specified net power draw in the pilot vertical mill using the appropriate parameters for the energy specific selection function and the breakage function, both determined using a conventional batch ball mill and a series of laboratory grinding tests.
It seems from the above that each application will be specific and will require a specific analysis. Vertical roller mills can have lower power than ball mills in most applications for dry grinding. One comment that I did not see here is the potential for differential grinding, especially in vertical mills, but also in ball mills.
promote consistent grinding • low specific power consumption: – reduce variability in the load parameters (mill table power, mill differential pressure, mill fan power) – reduce specific power (mill fan and mill table). Control technology and structure Traditional PID single input/single output control has some inherent disadvantages
Optimization of Cement Grinding Operation in Ball Mills Several energy efficient options for cement grinding are available today such as vertical roller mills, roller presses (typically in combination with a ball mill), and clinker pre-grinders with...
The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent.
the vertical mill can continue operating at its nominal capacity, uninterrupted. It simply ensures the flexibility to adapt to a wider range of feed conditions. Because of its excellent grinding economy, the HRP allows your plant to maintain the same specific power consumption (kWh/ton) as before its installation. Low maintenance, high stability

Combining wet grinding, the materials processed by ultrafine vertical mill like calcium carbonate are always characterized by high whiteness, high capacity, low iron content, low power consumption. It is the ideal pre-processing mill which should be given priority to by large-scale paper-making plants before wet grinding.
Motor power and media addition. The power drawn by the Vertimill motor is required to establish the grinding rate. Motor power should be measured using corrected power. As the grinding media wears fine enough to be carried out by the uprising velocity in the mill, the total media charge will diminish, and the power draw will decrease.
The Poly-Mill industrial mill is the ideal solution for milling a wide range of bulk products. Each milling system requires a specific solution according to the expected particule size. The Poly-Mill grinder can be fitted with several easily interchangeable milling tools to adapt the specific needs of each application.
