ZR/R-Series

The ZR/R bead mill series is designed for products with low to medium viscosity. In the process zone with rotating rotor and drum, differential peripheral speeds up to 21 m/s are possible. Variable overdrives between rotor and drum achieve a highly efficient centrifugal bead separation adjusted to product viscosity. The controlled and definable bead pressure enables optimized grinding intensity for each product.

High power density with small grinding chamber

  • The extremely high power density up to 5 kW/l and the centrifugal bead separation result in optimal conditions for grinding applications down to the nanometer range.
  • The power input of the ZR180 is between 40 and 50 kW, with a grinding chamber volume of 12 liters.

Centrifugal separation with rotating safety screen

  • The centrifugal principle allows the use of 0.1–0.8 mm beads for a wide range of viscosities.
  • High recirculation flow rates up to 5.000 l/h enable narrow particle size distributions and, in combination with the external product cooling, the grinding of temperature-sensitive products.

Ultra-fine dispersing for large batches

  • The high flow rate capability guarantees a steady continuous operation.
  • Due to the low-maintenance mechanical seal, downtimes are minimized.
