The specific energies (SE) shown in Table 1 are based on net power. Prony brake calibration data was used to determine the net power for the pilot vertical stirred mills (, 2011).The no-load power draw of one of the VTM-1500 installed at Minas-Rio was measured during the unloading of the ball charge.
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.

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
The vertical slag mill is a vertical roller mill for grinding slag. The mill has simple technology, small land area, high grinding efficiency and low energy consumption. The specific surface area of the ground slag powder can be adjusted flexibly within the range of 400-550 m2/kg, and the activity is high, which can meet the various fineness requirements of customers.
seen, the vertical mill consistently presented lower net specific energy consumption than the ball mills which operate on the same circuit. The averages were 11.3, 11.7 and 6.5 kWh/t respectively for ball mill 01, ball mill 02 and vertical mill. Figure 5 – Net specific energy consumption of regrinding circuit.
