The Boston Shearmill provides high shear rates and tip speeds. The unit can accommodate processes that require milling of soft particles to less than 1 micron or hard particles down to 1 to 2 microns, often with just a single pass, the manufacturer says. Models are available from 15 to 125 hp, providing throughput from 5 to 250 gal, depending on feed rate and viscosity. All models feature an exclusive single mechanical quench seal, rated for 700 psi, and comply with 3-A standards.
