NPK fertilizers or composite fertilizers belong to what are defined as the mineral fertilizers consisting of the elements nitrogen (N), phosphorus (P) and potassium (K). This multi-component fertilizer is mainly produced in the manufacturing method of the drum granulation or compacting. Here the named insured components are granulated with the addition of water and other additives in the first case and compacted in the second case which means that they are cramped under high-pressure. After it the resulting granules are classified according to the screening result and crushed or compacted resp. granulated again.

The moisture which is necessarily introduced into the production is a fundamental problem in the further processing. The screening machines have to process sticky or hard-to-screen materials without clogging the screen mesh. Over the decades RHEWUM has developed special solutions for a lot of clients which have proved their value successful in practice.
