In the hammer mill, the particle size is defined by the sieve size selected for the mill. The BTM provides different sieve inserts that can be used to reduce the material size to as little as mm. An application example Developers of cell cultures used to use ball mills to reduce the particle size of initial blends. Ball milling is time ...
The decision to use a Planetary Ball Mill for this application was mainly based on the fact that it produces very small particle sizes which were considered an important prerequisite for more indepth analysis of the yeast cells. ... RETSCH sieve shakers AS 200 jet and AS 200 control are utilized for particle size analysis of fine powders which ...
Example The size analysis of a gold bearing ore crushed in a jaw crusher indicated that 80 % passed through a 2000 micron sieve. Further size reduction was completed in a x m wet ball mill rotating at 78 % of the critical speed to liberate the gold. Determine the maximum size of the balls at the commencement of grinding.
