A. Grinding roller grinds the materials directly. Its energy consumption is 10% lower than other types roller mill and 2560% lower than that of ball mill. B. No direct touch between grinding roller and disc and the special wearable alloy materials used in grinding roller shell and lining plates grant a long life expectancy of mill and save the costs on quickwear parts.

To improve the mixing homogeneity, wet grinding was adopted, and the extra water content added to each sample was fixed at 60 wt pct. The data in Table II show that the raw materials were uniformly mixed after mixing in a planetary ball mill (QMBP, Nanjing Nanda Instrument Plant, China) with a ball to powder weight ratio of 6:1 and rotating speed of 322 rpm/min for 30 minutes to form slurries.

SUMMARY AND GUIDELINES FOR MINERAL EXPLORATION AND DEVELOPMENT. 25 Brucite currently has a relatively small market (Simandl et al. 2006), largely due to the rarity of highgrade deposits in comparison to other more common magnesiumbearing minerals, such as dolomite and magnesite. Large, highgrade brucite deposits could be a source of material for a variety of industrial mineral applications ...

To reduce the size further, the powders could undergo milling, involving the use of ball mills or ring roller mills. Finally, increases in the calcination temperature and time lead to a reduction in the SSA and an increase in the crystallinity of MgO, along with the agglomeration of particles, thereby reducing its reactivity [ 5, 74, 75 ].
