Highly efficient vibration screen for urea granules


Meike Schulz, RHEWUM GmbH

As the consumption of food increases worldwide, so does the demand for fertilizers. For these reasons, one of our customers has opened another plant for the production of urea fertilizers. He relies on the high quality and efficiency of RHEWUM screens.

The hygroscopic characteristics of urea can lead to lumping and clogging of the screen cloth, which has a negative effect on screen efficiency. As a pioneer of directly excited screening technology, we understand this problem and attach great importance to screening machines with automatic mesh cleaning mechanisms.

For the classification of urea granules, we use double-deck screening machines with an integrated lump screen to gently remove the lumps produced during the upstream process. We have designed 4 RHEWUM WAU screening machines which screen in 4 fractions: lumps (>15 mm), coarse particles (4 - 15 mm), main product (2 - 4 mm) and fine particles (<2 mm).

In order to guarantee a constant distribution of the material distribution, we rely on our RHEWUM SV feeders. They have an inner vibrating conveyor plate which is driven by two external out-of-balance motors. Furthermore, the static housing enables a dust-tight flange connection as well as inspections and maintenance during operation.

The tests carried out at our technology centre in Remscheid in advance enabled us to test the characteristics of the product on our machines in pilot plant size and thus to design the optimum machine that suits the customer's stringent requirements.

Do you have any questions or a similar screening task? Then feel free to contact us via our contact form. We are looking forward to your inquiry!
