Proven Excellence. Discus Grinding System The universal Grinding System CHEMICAL INDUSTRY a Business Field of NETZSCH Grinding & Dispersing

NETZSCH Discus Grinding System The universal Grinding System Discus is the byword for high-performance agitator bead mills with disk agitator. The high length/diameter ratio, the different grinding disk geometries, the various material options, as well as the highly-efficient grinding bead separation system facilitate an application-specific design of this machine for your particular task. The highest throughput rates with significantly narrower residence time distributions and therefore more intensive grinding with consistent stress intensity are guaranteed with the optimized Discus disk agitator...

NETZSCH Discus Grinding System Mode of operation of the DCC preclassifying separation system in an horizontal bead mill with disk agitator with 0.3 mm glass grinding beads at a water flow rate of 600 l/h

The Model DCC Preclassification System The highly efficient, dynamic centrifugal separation system facilitates the use of grinding beads of various densities, matched to the application. In addition, it allows the use of grinding beads up to 0.4 mm in diameter. The separation system ensures that the mill can be operated far below the critical point of grinding bead compression, even for products with challenging rheological properties. This means that operational performance is extremely stable, shutdown due to overpressure and exceeding the permitted temperature limits is avoided and grinding...

NETZSCH Discus Grinding System Optimum Grinding Bead Activation TetraNex® – The grinding system for optimum energy input The NETZSCH Discus agitator bead mills are equipped with the TetraNex® grinding system. The TetraNex® grinding disk, which replaces the familiar TriNex® grinding disk, is available in the standard design and in the TetraNex® Plus version. While the front side of the standard version is smooth, just like the TriNex® version, the TetraNex® Plus disk has special activation elements. These activate the grinding beads reciprocally in the axial direction, which leads to increased...

Horizontal agitator bead mill with Discus 500 disk agitator

NETZSCH Discus Grinding System Specifically matched grinding cham Material options for every product In order to satisfy the requirements of the broadest array of products and to guarantee product compatibility, we offer grinding tanks and agitator shafts made from a variety of materials. Matching the grinding system material to the product properties facilitates low-wear operation of the mill. Contamination of the product is thereby avoided. This leads to an enormous expansion of potential applications for the machine. The inner pipes of the grinding tank that come in contact with the product...
