Boston Shearmill CX Inline Wet Mill for Chemical Processing

The Boston Shearmill^® CX (BSM CX) series of chemical inline wet mills surpasses the capabilities of conventional shear pumps and colloid mills by providing very high throughputs at extreme shear rates.

OVERVIEW

Boston Shearmill® CX is an inline wet mill for chemical processes where product performance depends on particle reduction, tight dispersion control, and repeatable uniformity. When a shear pump or general high shear mixer can’t reach the required size distribution or stability targets, wet milling provides the intensity needed to reduce particles and improve consistency at production throughput.

Use this page to size a Shearmill® CX configuration around your flow rate, viscosity range, and particle reduction goals. For a clear “mixing vs milling” decision framework, link to the wet-milling section of our high shear mixer guide, then return here for final equipment selection.

HOW IT WORKS

Boston Shearmill CXs are constructed of a multi-slot rotor turning at high speeds in close proximity to a multi-port stator. Each shear head of the homogenizer consists of a rotor and stator, each with a double ring design. This results in three distinct, high intensity work zones at each rotor / stator location where the mixture passes:

between the first set of rotor slots or teeth and the first ring of slots on the stator
between the first ring of slots on the stator and the second ring of slots in the rotor
between the second ring of slots in both the rotor and stator

Models with three shear heads provide nine high shear work zones to handle your toughest processing needs.

They are capable of processing very high throughputs at extreme shear rates producing an average mean droplet size of 1-3 microns.
