Boston Shearmill Wet Mill/Homogenizer for Particle Size Reduction

How it Works | Specifications | Options | Datasheet


The Boston Shearmill (BSM) series of inline wet mills surpasses the capabilities of conventional shear pumps and colloid mills by providing very high throughputs at extreme shear rates. They meet the toughest hygienic standards and are 3-A compliant.

Particle size reduction is important in the fooddairybeverage and other industries, and this product is a standout. For processes requiring milling of soft particles to <1 micron, or hard particles down to 1-2 microns, the BSM produces superior particle size reduction, often in just a single pass at high production rates.

Wet milling substances with rotor-stator machines provides several advantages. Designed to run 24/7, our wet mills mix, disperse, emulsify, pulverize, macerate, crush, homogenize; reduce solids particles with minimal dust formation; and withstand uneven flow patterns, jolts, and pressure fluctuations.

The Admix Boston Shearmill is routinely used for for tomato paste standardizationsalad dressing and mayonnaise processingpet food productionflavor emulsionspharmaceutical preps and API blending, polymer blends, and more.
