Mixer Mill MM 400 11 Feed material: hard, medium-hard, soft, brittle, elastic, fibrous Material feed size: ≤ 8 mm Final fineness: ~ 5 µm Setting of vibrational frequency: digital, 3 - 30 Hz (180 - 1800 min-1)(PDF) Selection and design of mill linersThe appropriate design of liners continues to be an issue on many mills worldwide. Loss of milling capacity especially at liner change, uneven wear lives along the mill.Optimization of mill performance by usingliner design purposes. Many simulation tools exist to obtain the necessary information about media trajectories. Data are used to avoid the risk of liner and ball damage by projecting balls directly on the shell liner. Figure 3b illustrates this issue. Obviously, a good liner design .design of ball mill pdf(PDF) DESIGN AND FABRICATION OF MINI BALL MILL.
