The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
Differential pressure transmitters measure the difference between two pressures. Differential Pressure Transmitter converts pressure measurements, into a proportional 4-20 mA or a 1 – 5 Vdc output signal, that functions as the input to a controller, recorder, indicator or similar device.
In turn, a higher ball impact led to a fracturing of growing polymer chains, resulting in a lower DP (see fracturing tests, Section 1.2 in the Supporting Information). 36, 37 The highest DP was achieved using milling equipment made of Si 3 N 4, so we continued to use it and investigated the influence of the milling time (PPP PBM ‐4 to ‐8 ...
