摘要：Paper presents a concept of the mobile line for the production of granulated fertilizer from digestates and ash mixtures. The main assumption of the designed line is its mobility which allows line work in the place of production of digestate. The premise for developing such model of line was the fact that the transport of highly hydrated digestate, as well as its dried form, is not advisable for economic reasons. More advantageous solution is to collect the digestate at the place of its production and it is processed into a fertilizer. Loose components, characterized by high bulk density, can be delivered to the place of production and the same means of transport can be used to transport the produced fertilizer to warehouse. This production model allows to process the digestate produced in several biogas plants, using one production line and reducing the cost of production. of fertilizer granules and the mobile line is transported to the next post-fermentation production point. Based on an analysis of the raw material characteristics and preliminary research on the raw materials mixture granulation process it was assumed that the stage of 3 hrs mixture stabilization time is required in the line.
