Dewatering sieve RHEWUM WAFL

As the ultimate dewatering sieve for fine and finest solids, the WAFL offers a unique extremely advantageous combination of the vibration types linear vibration and direct excitation. As a result, it achieves highest dewatering rates and optimized residual moisture contents in wet screening.

Powerful magnetic vibration heads enable high-frequency vibration and thus ensure maximum dewatering by overcoming cohesive forces. At the same time, low-maintenance unbalance motors ensure material transport even at low inclinations.

Advantages of the WAFL dewatering sieve

  • Highest dewatering rates
  • Optimized residual moisture of approx. 8%
  • Saves additional drying and energy costs
  • Vibration amplitudes are adjustable during operation
  • Particularly flat construction
  • Quick exchange of screen cloths without entering the machine
  • Perfect for critical separations
