Union Process Produces Unique Laboratory Attritor for Biotech Application

Akron, Ohio...Union Process, Inc., known globally as a manufacturer of size reduction and dispersing equipment for research and industrial applications, has produced a first-ever 01-HD Laboratory Attritor with a water-cooled shaft.

For this application of dry reactive milling of organic compounds, Union Process modified its typical design to specifically meet the customer's requirements. Those requirements included a special water-cooled shaft and a very tight clearance of just 1-1/2mm between the arms and the tank wall that necessitated increasing the length of the tungsten carbide-coated agitator arms. The customer's application also called for closing off the entire processing environment in order to allow grinding under inert gases. There is a one-piece, stainless steel cover with a MECO shaft seal, gas inlet and outlet, and a charging port for grinding under inert gas in a closed system.

This Attritor has a gross tank capacity of 1400cc and a media volume of 760cc. The 01-HD Lab Attritor has been designed to allow easy removal of the grinding chamber from the mill. This allows the user to further work with the ground material under a hood.

The one HP, T.E.F.C. motor is controlled via a variable frequency controller installed in a NEMA enclosure. An LCD Operator Interface Module (OIM) displays agitator RPM, motor AMPS, and motor HP use.

The versatile Union Process Laboratory Attritors allow users to choose between wet and dry grinding, operate in controlled temperatures, vary grinding speed, choose different tank sizes and shaft/arm designs, change media size and type, and get precise energy consumption information, all on the same machine. Results can be replicated from one test to another and Attritors can be used for formulating, quality control, and, in the case of the 1-S model, scale-up studies.

Union Process is the inventor and developer of Attritor technology and manufactures wet and dry grinding mills as well as small media mills.
