Sugar - custom made to customer specifications!

Sugar is usually offered in different particle sizes depending on sales requirements. Refined sugar, for example, has a much coarser particle size than powdered sugar.

The requirement: Fifteen different particle sizes

A customer approached RHEWUM with a request to offer fifteen different particle sizes for sugar products. The customer supplies a number of different sugar processing industries, including companies as diverse as beverage manufacturers and bakeries. RHEWUM was therefore asked to provide screening machines that could process the feed material in three stages from very fine classifications to rather coarser separations in the final stage.

The solution: Versatile high-performance machines

Machines of the RHEsono type were used for the fine separations. Here, a high-frequency beater bar movement discharges the screenings at right angles from the screen mesh - the inclination of the mesh enables the screenings to be transported over the screen. For the two stages with coarser separations, smaller machines of the RHEmoto type were used. Maintenance-free unbalanced motors located outside the screen housing transmit high-frequency vibrations via oscillating axes directly into the screen cloth. These high accelerations enable precise separations and allow the use of this machine type even with sticky materials. Thus, RHEWUM was able to meet the customer's requirements by combining two machine types.
