What causes difficulties in the granulation and molding of bio-organic fertilizer?
In the actual operation of bio-organic fertilizer production line s, manufacturers often encounter issues such as low granulation rates, loose or easily broken granules, and excessive powder. These problems severely impact the product's appearance, packaging efficiency, and market competitiveness. In reality, granulation difficulties are rarely caused by a single equipment issue; rather, they usually stem from a combination of factors, including raw material conditions, process parameters, additive ratios, and improper equipment calibration. This article breaks down the core causes and offers practical, actionable solutions. Improper raw material moisture content is the primary cause of granulation failure. Bio-organic fertilizer granulation has strict moisture requirements, with the standard moisture content needing to be controlled between 25% and 30%. If moisture is too high, the material becomes overly sticky, leading to machine clogging, roller adhesion, and clumping, which pr...
