Boston Shearmill®
High Intensity Wet Milling, Homogenizing & Particle Reduction

High Intensity Wet Milling, Homogenizing & Refilling - Boston Shearmill®The Boston Shearmill and Boston Shearpump series of sanitary in-line high shear mixers surpass the capabilities of conventional shearpumps by providing very high throughputs at high to extreme shear rates. They are designed for continuous duty, running 24 hours a day / seven days a week! This series of in-line emulsifiers and wet mills will mix, disperse, emulsify, pulverize, macerate, crush, homogenize, and reduce solids particles. They withstand uneven flow patterns, bumps, jolts or fluctuations in pressure.
