The combination of the RHEsono and RHEmoto screening machines with direct excitation of the screening mesh is used for precise screening in the fine to medium grain range. 

In the upper decks, the unbalance motors provide the necessary vibration amplitude to efficiently mix medium to fine grains, while in the lower decks electromagnetic vibrating heads provide the necessary acceleration for deagglomeration of fine to very fine grains. Both drives have cyclically adjustable cleaning functions, which support a permanent keeping free of screen cloths even with difficult material.

Advantages of the RHEfino^®

• No clogged screen mesh due to automatic and adjustable cleaning pulses.

• Highly efficient vibration transmission and thus low energy consumption

• Continuous production even in the event of a drive failure

• Static housing with fixed flanges and very low dynamic loads
