NETZSCH Fine Particle Technology (Exton, Pa.) has introducesd a new upgraded line of Mini and MicroSeries agitator bead mills for wet grinding of small batches. Designed for laboratory and sample grinding, the Mini and MicroSeries mills accommodate different grinding chambers that vary in fabrication and size for specific applications and can grind particles down to 10 to 20 nanometers in size. The new design is more compact, and ancillary equipment is now mounted on the mill. Users can control cycle time, system alarms, measurement of motor power and data logging capability from a color touch screen mounted on the mill. The seal flush system and cooling water hoses are integrated directly into the machine frame. The line comprises three mills, each with grinding chamber parts fabricated with different materials for specific applications. For metal-free grinding, the MicroCer features chamber parts in wear-resistant zirconium oxide and is designed for solvent-based applications. The general-purpose use MicroFer is designed in stainless steel and has a cooled chamber. The MicroPur uses polyurethane parts for grinding water-based products.
