Effect of Ball Mill Treatment on the Physicochemical ...

Abstract: The effects of ball mill treatment (0, 2, 4, 6, 8, and 10 min) on the physicochemical and digestible properties of scallops (Chlamys farreri) protein (CFP) were investigated. The CFP particle size decreased with increasing ball-milling time. The content of free sulfhydryl (SH) of CFP increased from 13.08 0.25 mol/g protein to 18.85 0.24 mol/g protein when the ball-milling …

THE OPTIMAL BALL DIAMETER IN A MILL

(2) 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.

Ball Mill - SlideShare

18.11.2008· 2. Basic principle Ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system. There is a specific operating speed for most efficient grinding. At a certain point, controlled by the mill speed, the load nearest the wall of the …
