The efficient operation of separation and classification processes, whether wet or dry, relies on continuous particle sizing for:

  • Precise and automated closed loop control.
  • Upset detection.
  • Filter breakthrough detection.
  • Minimizing waste/unnecessary recycle.
  • Attaining exemplary product quality.

Separation and classification processes divide an incoming stream into two on the basis of particle size – a product or feed for further processing, and a return/waste flow.

Real-time particle size data ensure precise control of the cut point between these two streams, optimizing product quality and minimizing waste. In cement finish milling circuits, for example, automated control of the classifier is a proven strategy for meeting cement specifications while maximizing mill throughput, by reducing recycle rates.

The ability to instantly detect a problem safeguards product quality. For certain separation processes, it may also prevent uncontrolled release of particulate matter. A typical example is the use of flocculation and classification within the minerals industry to recycle water.

For both wet and dry separation processes, Malvern works in partnership with equipment suppliers and customers, bringing the analytical know-how to engineer analytical solutions that seamlessly within existing control platforms and accelerate the development of effective automated control strategies.
