More Capacity – More Beads

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 down to 0.3 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.

Based on a Proven Concept

The Discus Intensive Rotor is the latest development in a long history in grinding technology. Based on decades of research and development and technical competence, we developed Discus, an intensive rotor that shows again an impressive result in separation, flow and grind efficiency.

Increased Power Input

The Discus Intensive grinding system optimizes the movement of the grinding media so that higher power input and production output are achieved with a simultaneous increase in grinding efficiency.

We Keep Cool

The use of state-of-the-art highperformance ceramics with high thermal conductivity increases the cooling of the grinding chamber. It is also much more wear resistant than steel and increases the service life of the grinding chamber many times over.

We Increase Flow Rate

The Discus Intensive Rotor allows much higher flow rates without reaching the maximum pressure. This helps run highly viscous product at high flow rates, and also allows running of an effective circulation operation for products that have specific energy requirements starting with, around, 100 kWh/t and higher.

1. The customer has to guarantee a shelf life of minimum one year, so he is running a second pass to get a clean product. When we changed to the TetraNex^®/TetraNex^® Plus design and the conventional separation system, we were able to increase the productivity by 50% to 60 kg/h but still 2 passes are necessary. The temperature outlet was at the product limit.

2. For this reason we changed the liner material to NETZSCH-Ceram C so that we were able to increase agitator speed without reaching the maximum temperature. The production rate increased by another 40% to 85 kg/h but still a second pass was necessary to get a clean product.

3. By installing the double conical spacers we were successful in getting a clean product and at a flow rate of 190 kg/hr – this is roughly 4-6 fold increase

4. Through an additional modification of the grinding media separation and the complete use of the grinding chamber as a process volume, a further significant increase in product output to 400 kg/h in one pass was achieved.
