Vibratory sieves of the type RHEmoto^® are utilized for precise separations within the fine and medium particle size range, specifically for aggregates. With automatic cleaning and a significant number of motors, these screens ensure utmost reliability.

Maintenance-free unbalanced motors located outside the screen housing transmit high-frequency vibrations via swinging axes directly into the screen mesh. These elevated accelerations facilitate accurate separations, making this screen service for aggregates ideal for handling narrow particle size materials, including those with adhesive properties.

Advantages of the RHEmoto^® vibratory sieve

• No clogged screen meshes thanks to automatic cleaning

• No dynamic loads thanks to static housing

• Vibration amplitudes are freely adjustable

• Quick exchange of screen cloths without entering the machine

• Continued production even if one drive breaks down

• Highly efficient energy transmission and therefore low energy consumption

• Motor inspection possible during operation

• Optimal separation of aggregates with narrow particle size distribution

• Hygienic design suitable for food and pharmaceutical industries, preventing contamination and meeting strict industry standards

• Easy to operate with user-friendly features for plant operators

• Improved product purity, operational efficiency

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

  
  

In our dewatering screen RHEdry, linear directed vibration with high frequency enables efficient dewatering of medium- and coarse-grained solid particles from suspensions.

Due to its optimized design with a simple and at the same time stable structure, the RHEdry dewatering screen offers a cost-effective solution for many applications in wet processing. It is driven by two low-maintenance 4-pole unbalance motors, which are mounted above the machine in a freely accessible position for maintenance. 

As the ultimate dewatering sieve for fine and finest solids, the RHEhydra^® 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.
