Granulation application in organic compost fertilizer production allows making better use of nutrients, it also significantly reduces the amount of fertilizers needed to be poured in the soil and reduces the cost of their storing, transportation and spreading in the soil. Granulation process parameters and factors affecting the cattle manure-based compost of organic granular fertilizer physical-mechanical properties were investigated. Theoretical and experimental studies have shown that the produced pressed fertilizer qualitative traits and physical-mechanical properties of the pelleting process were influenced by the technological parameters of granule production. It was determined that the kinetic friction force occurs when granules slide against metal and plastic friction surfaces, which depend on the material properties, friction surface condition and sliding velocity. The granule pourability was influenced by the fractional composition of the pellets which determined the natural slope angle (43º-47.6º) and inrush failure angle (26º-22.7º).
