Wet Milling vs

Media milling is known as the classical wet milling technique this process treats a dispersion of concentrated drug in an aqueous or non aqueous liquid medium with milling balls The process is advantageous in its economic value and ease in scaling up However there are also significant drawbacks to this method Due to intensive mixing forces in the vessel erosion of the mill balls is

Bond formula for the grinding balls size calculation

  C the mill drum rotational speed of the critical speed D the mill internal diameter m At result B = 25mm or less necessary to use the correction factor the grinding balls average diameter should be mm in the feed mixture We draw your attention a larger grinding balls need to use for future loads As practice shows

THE OPTIMAL BALL DIAMETER IN A MILL

 

The ball impact energy on grain is proportional to the ball diameter to the third power 3 E K 1 d b 3 The coefficient of proportionality K 1 directly depends on the mill diameter ball mill loading milling rate and the type of grinding wet/dry None of the characteristics of the material being ground have any influence on K 1.

Process Parameters Optimization of Silica Sand

  For milling speed since previous works usually used high speed ball milling which is more than 100 rpm the best speed for low speed ball mill is unknown Since higher speed results in higher collision between grinding balls and powder 7 the three highest speeds of the ball mill will be used which are 100 rpm 95 rpm and 90 rpm.
