Colloid Mill

Colloid Mills are your best answer for particle deagglomeration and primary particle size reduction.

Commonly used in the chemical and personal care industries, colloid mills are used to grind the primary particles of solids in a liquid slurry into much smaller sizes. The intent is to create a finer suspension of the solids within the liquid phase. Sonic’s colloid mills are also used to deagglomerate and disperse solids. Agglomerates form when solid particles fuse together. The grinding action of the mill breaks apart these particle clusters so the resulting finished product has a superior appearance and performance.

Sonic’s RotoMill has one of the most robust designs on the market today with oversized bearing chamber and movable shaft chamber.  This makes for a very stable, long running colloid mill.  The same unit allows for single or double flush sealing options without using a larger head.

Overview of Colloid Mill and Colloid Mill Systems

We offer standard units as well as customized systems that incorporate components upstream and downstream. These might include tanks, feed pumps for highly viscous fluids, pressure and flow instrumentation and PLC controls. Colloid Mill Systems are designed to help customers make the best products possible. Highly viscous fluids, like grease or mayo, typically require a feed pump to improve flow rate output of the mill. Gravity flow often isn’t enough. Sonic specializes in system customization to tie your entire process together. We design and fabricate our own PLC controls cabinets and programs to automate your process and provide safe operation.

HOW IT WORKS

Our Colloid Mills feature three shear points that subject material to a higher degree of grinding than conventional mills. A rough slurry is forced into a cavity formed by a spinning Rotor and fixed Stator and centrifugal force propels the material to the outside of the Rotor, causing intense hydraulic shear that breaks agglomerates and mills the solids within liquids. This allows for a smooth looking final product with improved shelf life.

Sonic’s RotoMill rotors and stators are designed with a patented and proven multi-angular system to provide superior shearing and grinding.

Standard Colloid Mill Design

A standard mill design includes the mill itself with built-in Rotor and Stator, an energy efficient motor operating at various speeds from 900 – 7200 RPM, a motor starter with power disconnect, all assembled on a stainless steel tubular frame. Casters for mobility or rigid leveling legs are standard. A feed funnel is typically included but many customers connect their own tanks or feed vessels.

Sonic pays special attention to detail, providing clean welds on all frames and uprights for electrical cabinets.
