Stirred media mills have been increasingly used in ultra-fine grinding. The VXPmill is a vertical high speed stirred media mill for grinding mineral ores with high efficiency. Since it is a new technology in the industry, there is little understanding on the breakage kinetics of

of the vertical mill got better, which reinforces the importance of classification system role for the entire grinding circuit. Nevertheless it will be very valuable to keep monitoring the behavior of the regrinding circuit of concentrator II, in order to better evaluate the effects of operational parameters in the vertical mill performance.

The determination of the specific energy depends among others on the mode of grinding operation. For a grinding process in a circulating mode (multi-passes), the specific energy can be determined as follows: (1) SE = ∫ 0 t N τ − N 0 d τ m P Where m P is the mass of the solid product, N(τ) is the power at the time τ and N 0 is the no-load power. If the grinding media wear is significant ...

2.2. Milling Process. As previously mentioned, the machining operations are carried out using HAAS CNC Milling VF-6 machine as shown in Figure 3(a) under dry condition.

vertical roller mill (VRM) is now successfully being used for many clinker grinding applications and is rapidly becoming the standard for new grinding installations. The first such vertical roller mill installation in the United States was part of a total plant expansion and began operation in August of 2002.

A detailed test work was carried out with an industrial semi-autogenous (SAG) mill in a copper plant in close and open circuits to specify the effects of ore characteristics and operational parameters on mill performance. In addition, the shape of mill product particles was studied to monitor breakage events as a function of ore strength.
