A laboratory air-classifying impact mill was used for the dry grinding, and a stirred ball mill attritor was used for the wet grinding. Products of as near the same size distribution as possible were prepared by each method, i.e., nominal minus 27 micrometers ..mu..m with a mean particle size of 10 to 12 ..mu..m.
Since for the ball mill design we are using 80 passing, the required value of C2 for the ball mill will be equal to1.20. C3 is the correction factor for mill diameter and is given as 3 2.44 0.2 3 However, it is important to note that C3 0.914 vessel used in producing the ball mill was got from a
Since the early 1800s companies have manufactured machines that were engineered to process wet materials. As time went on people formulated new products that required microscopic particles. As the demand increased for these materials the ability of the older ball mills were not able to keep up.
Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
