DEWA-F is a multifunctional complex for producng organo-mineral fertilizers in a form of gel. Fertilizers can be produced from peat (turf), biohumus, sapropel, etc. Fertilizers produced in DEWA-F have higher content of humic acids.

Horse or poultry manure, processed in DEWA-F, is almost completely disinfected and is also suitable for use as fertilizers. Additional desinfection (decontamination) can be made by a static reactor.

DEWA-F make additional micronization of raw material up to 50…110 mkm. If raw is not prepared we recommend to use our Wet Milling Machine (WMM-2)

Processing Stages

Stage 1. Preparing of Raw Materials

Raw material for organo-mineral fertilizers (OMF) normally has solid includes sand, stones, wood chips and others, which do not allow to process it further.

Preliminary sieving typically is not very effective for and does not separate tiny stones and sand from the peat, sapropel or brown coal which are used as raw materials.

The best solution for preliminary preparation of raw material is a Wet Milling Machine which makes several function:

  • wet milling of peat (turf) till 200…300 micron
  • crushing of stones, sand and other includes till 100…200 micron or lower
  • production of homogeneous (uniform)slurry with a consistency similar to thick yogurt.

Stage 2. Processing

Slurry, produced in a Stage 1 then processed in RIA or static reactors. If Stage 1 is eliminated then peat is milled and homogenized in a DEWA-F based on RIA.

That allows to produce a final product with a grainsize D90 below 120 micron.
