Application

Cleaners remove contaminating materials that are specifically heavier than fibres. In waste paper processing, these contaminants are, for example, sand, glass, stones or staples. The feed through the inlet is tangential in order to set the flow of material in rotation. The heavier particles migrate outwards due to the centrifugal forces and are precipitated downwards, while the lighter fibres in the middle of the vortex rise upwards and are passed on as accepted material. Pressure measurements in the inlet, outlet and overflow are required to regulate the process and ensure that it stays at the optimal operating point.

Your benefit

Reliable
High operational reliability, even with abrasive contaminants in the process medium, due to ceramic measuring cell
Cost effective
Operating the cleaner at the optimal operating point
User friendly
Minimal servicing thanks to maintenance-free measurement
