Ball Mill

12/12/2014INTRODUCTION Planetary Ball Mills are used wherever the highest degree of fineness is required. Apart from the classical mixing and size reduction processes, the mills also meet all the technical requirements for colloidal grinding and have the energy input necessary for mechanical alloying processes. The extremely high centrifugal forces of the Planetary Ball

Disruption of Phaffia rhodozyma cells and preparation of

02/08/2018Due to a thick cell wall, P. rhodozyma is difficult to hydrolyze, and only a large enzyme dosage could lead to cell disruption. Physical methods, such as the ball mill by Bead-Beater, would increase local temperature and lead to astaxanthin degradation because of the sharp attrition (16). In the present study, the cell walls of the yeast were successfully disrupted
