| Abstract [eng] |
In this work, different sources of nitrogen and potassium for 8–0–30+S fertilizers’ granulation were used. Fertilizers were granulated using a drum granulator and a fluid bed granulator. All used waste materials were found to be suitable for the production of compound fertilizers. The best properties of the compound fertilizers (marketable fraction part – from 63.0 % to 85.0 % and static strength of granules – from 34.60 N/gran. to 43.18 N/gran.) were obtained when the content of irrigation water in the raw material mixture was 7–9 % (15–20 ml/200 g of the mixture) and the recycle was 10–20 %. It was found that the properties of the fertilizer depend on the irrigation water content and the particle size of the raw material. The origin of raw materials had a negligible influence. The 8–0–30+S compound fertilizer properties were worse when using a fluid bed granulator than a dryer drum granulator. |
