Sugar is among the most demanding screening materials. It draws moisture, tends to agglomerate and has abrasive properties. To achieve maximum precision in separation under these conditions, vibration screening machines with direct excitation of the screening mesh are a good choice.

The RHEsono vibration screening machine utilizes magnetic vibrating heads to transfer motion impulses directly to the screening mesh. The impulse can be precisely adjusted to the properties of sugar. The screening mesh begins to vibrate, the sugar is deimpacted at a high frequency, agglomeration is reduced. To counter any clogging that might nevertheless occur, the RHEsono has an additional cleaning pulse which clears the screening mesh at regular intervals. This neither interrupts the screening process, nor does the pulse negatively affect separation precision.

This technology allows the RHEsono to achieve highest precision in separation at high throughputs, in this case more than 200 tons of sugar per hour. The RHEsono separates the material into five fractions, the finest of which is at 0.15mm. Made of stainless steel, the RHEsono is resistant to corrosion and ATEX certified to meet local operating conditions.
