Multifrequency excitation increase efficiency in the vibration screening

In the process, there are many materials that can be due to their particle shape and / or surface properties are difficult to separate the classical screening machines. A mechanical transfer system that generates multi frequency oscillations, promises help.


In the novel separation processes of Kaiser Engineering is a mechanical adjustment system with multifrequency vibration adapters. The engine vibrates a screen, it produces oscillations that are transferred to the screen body of the machine. The screen body mounted on multifrequency adapter handles the vibrational energy of this, they converted from a one-in a multi-frequency, amplify them to the 200 - to 500-fold and finally transfers it to the screen. Here, the multifrequency excitation evenly across the screen surface by means of resonance ring (s) or transfer rods. Because of built-in buffer system filters do not get any high-frequency oscillations back to the screen body of the machine.

The special feature of this method is that it is purely mechanical work without additional external power supply.

Increase the throughput

In conventional vibration screening equipment all particles are under the influence of a single frequency produced by the engine. Consequently, the particles are distributed only on the screen surface. When using the multi-frequency method, however each individual particle is its own resonance frequency, since a wide range of frequencies is simultaneously available on the screening surface and the distribution of frequencies on the screen surface for more than ten changes per second. This "strong impulse to shoot through the entire thickness of the layer of material and cause a continuous mixing of the material. The result is that the material virtually at the screen surface "froth" is. This vibro-moving layer effect may be substantially greater thicknesses are processed as usual, like a practical example shows: A manufacturer of highly abrasive tungsten carbide could on a conventional screening a maximum throughput of 25 kg / (hm ²) reach. After switching to the multi-frequency method, the throughput performance of his investment increased to 560 kg / (hm ²).

Crushers in minerals processing

There is lots on crushers and screeners in this book Will's Mineral Processing. We are looking for a good book review on this. So if you could write one, please let us know.
