Attrition Mills - Powder Metallurgy - Beyond Discovery

Milling in an attrition mill (Fig. 24) is effected by the stirring action of an agitator that has a vertical rotating shaft with horizontal arms. This motion causes a differential movement between the balls and the material being milled, thus providing a substantially higher degree of surface contact than is achieved in tumbler or vibratory mills.. Fig. 24 Attrition ball mill

Effect of homogenization method on DNA yield and fragment size

Fragment size was significantly impacted by the homogenization method as the shearing method (rotor-stator) generated a continuum of fragments starting at a high of around 15 kb (Fig. 1). The HT Homogenizer generated a narrower range of larger fragments than the rotor-stator, as did the mortar and pestle. The CryoGrinder produced a much broader ...
