In organic fertilizer production, clogging of organic fertilizer crushers can easily lead to organic fertilizer produciton line downtime and equipment loss. Solutions must be developed from the source and throughout the entire operational process to ensure production efficiency.
First, optimize the raw material pretreatment process. Excessive moisture content or large impurities in the raw materials are the main causes of clogging. Screening and dehydration should be added before pulverization. Vibrating screens should be used to filter out large, hard objects from the raw materials to prevent them from getting stuck in the pulverization chamber. For materials like livestock and poultry manure and wet straw, the moisture content should be reduced to 15%-20% through airing or dehydration equipment before feeding the grinder to reduce the chance of material sticking and clogging.
Second, precisely adjust the grinder parameters. Adjust key equipment parameters based on the characteristics of the raw material. When pulverizing lightweight raw materials like straw, increase the feed rate and widen the discharge port. When processing mixed materials like manure, slow the feed rate and use a larger screen to prevent material accumulation on the screen.
Finally, standardize operator procedures. Operators must undergo pre-job training to master the feeding rhythms of different raw materials and avoid feeding large quantities of material at once. Regular inspections should be conducted on the operating status of the organic fertilizer equipment. If material accumulation is detected at the feed inlet, the equipment should be immediately shut down and cleaned; do not force it back on.
Finally, routine equipment maintenance should be strengthened. After daily operation, residual material should be cleaned from the crushing chamber to prevent clumping and hardening. Weekly inspections should be conducted on the pulverizer blades for wear, and blunt blades should be replaced promptly to ensure efficient cutting. These measures can significantly reduce the frequency of pulverizer blockages and improve production line stability.
