CDC Microtron USA, Inc.
Grayslake, IL 
(847) 548-8224
Web: www.cdcmicrotron.com
Product name: MicrotronSmall Media Mill
Attributes/comments: The new Mic­rotron small media mill utilizes a unique agitator assembly for managing the grinding media for optimum processing and temperature control. This state-of-the-art bead mill delivers uniform sub-micron dispersions, often approaching primary particle sizes. The new mills come in laboratory and production chamber sizes from 500 ml to 50 liter. Testing equipment available at the CDC Microtron USA, Inc. laboratory in the Chicago area.

Product name: DCP Nanostar
Attributes/comments: The new Drais DCP Nanostar Media Mill is, specifically, designed to produce the nanomaterials previously unattainable. The highly efficient energy utilization during nano-grinding via the use of ultra-small grinding media (down to 20 micron), superior product temperature control and the elimination of metal contamination are some of the key features of the new Nanostar. DCP Nanostar offers high energy density milling, internal true-media recirculation and the most efficient grinding media/product separation by centrifugal force. Drais DCP Nanostar sets new standards in wet grinding of high tech products down to nanometer range. Various sizes are available with linear mill scale up based on power consumption.

Eiger Machinery, Inc.

Product name: Lab M100 for Product Research
Attributes/comments:  The EMI lab­­oratory M100 mill is used for milling of abrasive slurries and others requiring metal free grinding. Sample volumes from 100 to 300 ml’s allow the processing of realistic dispersion samples using minimum amounts of raw materials. Capable of using media sizes from 0.1 to 2.0 mm and have ceramic components for purity grinding. These bench top mills are self pumping and self contained units and available with explosion proof components and monitoring instrumentation.

Product name: New Grinding Media of Zirconium Oxide – Rare Earth Stabilized
Attributes/comments: Glen Mills Inc. is introducing a new grinding media of Zirconium Oxide Rare Earth stabilized composition that gives mill users advantages over currently available beads. This material is 83% ZrO / 13% CeO with specific gravity 6.0-6.1. A longer bead life is assured due to the very fine grain size of the ceramic. The smooth surface, even as material is worn away, and very good roundness to roll, not gouge, will protect wetted mill parts.  The high density to plough through the thickest of slurries allows for using smaller diameters. Soon to be stocked in NJ with competitive pricing, the extremely tight size tolerance, and expansive size offerings makes these worth a test.

Hockmeyer Equipment Corp.
Harrison, NJ
(973) 482-0225
Fax: (973) 484-6114
E-mail: sales@hockmeyer.com
Web site: www.hockmeyer.com
Product name: Nano Mill
Attributes/comments: After extensive R&D, Hockmeyer Equipment has made rapid nano milling a reality. This is accomplished by mega amplification of feedstock recirculation through a field of micro media to produce nano dispersions in a fraction of the time of conventional horizontal and vertical mills. The Hockmeyer Containment Wall (patents pending) permits the use of media as small as .01mm and has an open area of about 40%. The containment wall is very large relative to the media field, allowing high flow of feedstock. Comparing the HCW to other mill separation devices, it has on average 100 times the flow rate.

New Product: ZirTa-Nor, Zirconia Toughened Alumina Beads
Attributes/comments: ZirTa-Nor, ZTA, is a long wearing, medium density media with low wear rates and excellent milling efficiencies prices in the same range as zirconia silica. This bead does not have hollows which cause excessive breakage and screen plugging. ZirTa-Nor is an excellent value for medium density grinding media, giving a long service life for minimal cost and no trace amounts of radioactivity. The whit bead has a 4.1 (2.5 kg/liter) density and is avaliable in sizes from 0.6 mm up to 3.0 mm. The beads are pre-conditioned and approved for use in food and cosmetic applications. Balls and cylinders are also available upon special order.

New Product: Q-03 Circulation Attritor
Attributes/comments: Union Pro­cess, Inc. has produced the Q-03, a small bench-top laboratory-sized circulation grinding mill. This smaller circulation attritor was developed so users can perform lab trials with the advantage of the circulation grinding system using much smaller samples (from 1/2 gallon to one gallon). The Q-03 circulation attritor offers all of the advantages of larger laboratory or production-sized circulation attritors, including a high circulation pumping rate, narrow particle size distribution, good temperature control and the ability to sample and make formulation adjustments on the fly.
