• Speeding Up Your Organic Synthesis with Ball Mills

  Apr 07 2015 · Investigation of the technological parameters reveals that the type of ball mill whether it is a mixer ball mill or planetary ball mill does not influence the outcome of the reaction. However variables such as the size and count of the grinding balls the milling material and the filling degree of the grinding bowls play an important role.

• Solids Choose the Right Grinding Mill Chemical Processing

  Sep 13 2010 · There are many different types of grinding mills (Table 1). Some devices such as ball mills are more suitable for coarse materials. These mills use "large" media ranging in size from 20 mm in diameter and up to produce material from about ten microns to mesh sizes. Attrition mills are more appropriate for "mid-range" size particles.
