Product name:MicroMedia–Ultrafine Grinding to the Lower Nano-Range
Attributes/comments:Buhler is launching the all new, pilot size, high-tech agitated bead mill, MicroMedia P1. The specific technology of introducing grinding energy and the internal product flow are especially designed for a safe and reliable use of extremely fine beads from 300 µm down to 20 µm. Depending on the requirements of different material systems, the operating conditions can be varied from "soft milling" up to "high energy grinding," in any case combined with unusually high flow rates. Highest levels of quality standards can be achieved, corresponding with narrow particles size distributions in the lower nanometer range. An outstanding feature of the innovative mill concept is the obtained results can be linearly scaled up to the production size mills of the MicroMedia series.
Product name:Dyno-Mill Research Lab
Attributes/comments:Willy A. Bachofen AG Machinenfabrik (WAM) has introduced the Dyno-Mill Research Lab which permits dispersing and grinding of low or high viscosity products to nano ranges; small batch volumes (>100ml) in a continuous or in a re-circulation process grinding products without metal contamination using ceramic components made of zirconium oxide or silicon carbide; removing the complete closed grinding container to clear or sterilize; and the use of small grinding media size from 0.05-1.0 mm.
CDC Microtron USA, Inc.
Product name:Microtron Bead Mill
Attributes/comments:The new patented Microtron bead mill has a unique double-helix bead band technology that produces uniform narrow particle size distribution resulting in micron or sub-micron dispersion, often in a single pass. The Microtron incorporates an innovative new concept in dispersion mechanics by maximizing energy transfer into a low volume, concentrated bead mass. Optimum control of the manufacturing process by use of a computer controlled operator system. Testing equipment available.
Charles Ross and Son Company
Product name:Model 400DL High Shear Mixers
Attributes/comments:The new model 400DL is an inline design for use in laboratory and pilot plant development efforts. The 1-3/8" diameter rotor is driven by a powerful 1 HP motor at speeds up to 10,000 RPM. All wetted surfaces are constructed in 316-stainless steel and are finished to suit the needs of the application. Optional finishes up to a mirror finish and special materials such as alloy are available. This model is also offered with an attached 2.5 gallon mix vessel, and a range of stator heads including the slotted, round hole, fine screen and Quad (four stage) designs. Special seals are available to permit operation in applications to 250 psi. High shear mixers are typically used for mixing, dispersion, emulsification, homogenization and particle size reduction of low viscosity products. These units are applied throughout the process industries and are often used to improve processing efficiencies such as shorter cycle times, smaller particle size and improved particle suspension.
Eiger Machinery, Inc.
Product name:Micro Media Mill
Attributes/comments:The new laboratory Eiger Micro Media Mill has the ability to process samples as small as 50 ml which can aid in screening formulations and of dispersion samples requiring fineness of particles. This new arrangement can use grinding beads down to 0.1 mm diameter and provide high shear forces through a variable speed agitator and pumping system. Process parameters can be monitored including kilowatt hours.

(252) 338-4705, (800) 906-7278
Product name:Hockmeyer Improves Milling Technology
Attributes/comments:Hockmeyer Equipment Corp. has developed two new enhancements to its high performance immersion mill. The first is a patented top auger that accelerates product flow through the mill, further reducing process time. The second enhancement is a scraper for the mill vessel. It is an integral part of the mill assembly and improves heat transfer from the jacketed wall of the vessel by constantly removing product and feeding it back into the mill.

Fax:+91 253 2350023
Attributes/comments:In the family of ceramic micro milling beads, Zirconox (zirconium oxide) beads are ranked as the highest density, 6.2gm/cc and lowest in wear rate. Looking to the worldwide demand for medium density beads, Jyoti has developed Zircosil (zirconium silicate) beads with a density of 4.6 gm/cc. Zircosil beads are cost economical, far superior in milling performance, density, hardness and in wear resistance as compared to other zirconium silicate beads available worldwide. This is achievable because of proprietary manufacturing technology.
Myers Engineering, Inc.
Product name:Model 850 Basket Mill
Attributes/comments:The Myers dual shaft basket mill offers the operator greater flexibility for a wide range of viscosities and tank sizes as the mill speed and the batch agitator speed operate independently. The Myers unit has a large heat-exchange shroud around the mill that removes heat at a rapid rate. This eliminates the need to slow the unit down to control heat build up. Customers are reporting reduced production times in the final milling stage and superior particle size distribution. Myers' laboratory now allows customers to test the superiority of this basket mill design. Customers are encouraged to contact the sales department for information on laboratory testing.
Netzsch Fine Particle Technology, LLC
Product name:MicroSeries Agitator Bead Mills
Attributes/comments:Netzsch has introduced a 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 in size. Ideal for laboratory and sample grinding, the MicroSeries line comprises three mills, 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 MicroCer 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, 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 feature 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.
