    Vibration mills in the manufacturing technology of slurry

    Aug 12, 2008 One of the CWSF manufacture steps is the comminution of coal sludge to have a particle size required by the combustion conditions. Vibration mills, which are more compact and energy-intensive that drum mills, can be used in the CWSG manufacture process. The rheological characteristics of CWSF obtained from unbeneficiated waste coal were determined

    The vibrating mill belongs to the group of mills that make use of impact forces. However, in contrast to the so-called impact mill, the size reduction in vibrating mills is primarily caused by the impact energy of the grinding media rather than by friction or by acceleration of the feed material. Figure 3 illustrates the vibrating mill with its
