May 10, 2007 — Netzsch Fine Particle Technology, LLC of Exton, PA has introduced its MicroSeries line of agitator bead mills for wet grinding of small batches (0.14 to 0.5 liter) with resultant particles down to 10 to 20 nanometers. Designed for laboratory and sample grinding, the MicroSeries line comprises three mills, each with grinding chamber parts fabricated in different materials for specific applications.

The general-purpose use MicroFer is designed in stainless steel and has a cooled chamber. For metal-free grinding, the MircoCer features chamber parts in wear-resistant zirconium oxide (composite SiC/Si3N4) and is designed for solvent-based applications. The MicroPur uses polyurethane parts for grinding water-based products.

All three machines are equipped with Netzsch’s proprietary ZETA grinding system. The MicroSeries also features an improved centrifugal separation system that employs grinding media from 0.05 to 0.8 mm in size, which the company says is the smallest in the industry.

MicroSeries machines are equipped with double-acting mechanical seals and adjustable hose pumps. Particles are continuously processed in circulation operation between the integrated circulation tank and the laboratory mill. MicroSeries units also feature swivel grinding chambers that simplify operation and thereby reduce product loss.

Each mill in the MicroSeries line can also be scaled up to handle larger volumes similar to those of Netzsch’s MiniSeries mills.
