Effect of mill diameter on the rate of initial grinding in

Mar 01, 1990 The vibration imparted is in a vertical direction and its waveform is observed with the synchroscope. Figure 2 shows the shape and dimension of the cylindrical mills used. The three mills, A, B and C type, were made of steel and had the same internal volume of about 177 cm3. Stainless steel balls of 7.0 mm diameter were used as grinding medium.

palla VIBRATING MILL

Vibrating mills have hitherto proved their worth as individual machines. Vibration grinding represents an economic and reliable solution since the required product grain sizes can be achieved in a simple continuous grinding process without air classifying. For over 160 different materials, from soft to very hard, the vibrating mill
