High-fiber materials—such as crop stalks, sawdust, and spent mushroom substrate—are characterized by high toughness, a tendency to tangle, and poor air permeability. During processing, they frequently cause machine blockages, result in low pelletization rates, and accelerate the wear of consumable parts. Standardizing operations across four key areas—raw material pretreatment, equipment components, operational procedures, and routine maintenance—is essential to ensure the stable production of the new type two in one organic fertilizer granulator.

Raw material pretreatment is fundamental. Fibers must be pulverized to a length of less than 5mm; long stalks can tangle around the main shaft's mixing teeth, causing the machine to stall or shut down due to overload. The carbon-to-nitrogen ratio must be controlled; the proportion of livestock manure to stalks should not exceed 3:7, as an excessive fiber content results in loose granules and a surge in material recycling. Moisture control is critical; the optimal moisture content for granulating high-fiber materials is 26%–30%. Excessive moisture causes material to stick to the barrel walls and clog screens, while insufficient moisture prevents the material from binding and forming granules. Impurity screening should be installed at the feed inlet to remove stones and wire, as hard debris rapidly wears down mixing teeth and liner plates. Small amounts of humic acid or bentonite can be added as binding agents to improve granule compactness and reduce dust caused by loose fibers.

Standardize operational procedures for the bio-organic fertilizer produciton line. Feed material continuously at a steady, low rate; avoid dumping large quantities at once, as fiber accumulation can jam the mixing teeth. Monitor the main motor current in real-time; if the current remains consistently high, reduce the feed rate immediately or stop the machine to clear tangled material. Extend the material's residence time in the barrel and lower the main shaft speed to ensure fibers are thoroughly kneaded and granulated. Avoid prolonged no-load operation; idling mixing teeth lack material cushioning, which doubles the rate of wear.

Regular maintenance minimizes breakdowns. Stop the machine every two hours to clear stalk fibers tangled around the main shaft, preventing motor burnout caused by rising resistance. Check mixing teeth for wear and inspect scraper clearances daily, performing weld repairs or replacements promptly when necessary. Clear fiber blockages from screen apertures at the end of every shift and replenish bearing grease weekly. For long-term processing of high-fiber materials, the cylinder is fully disassembled every two weeks to remove hardened fiber clumps; this practice significantly reduces equipment failure rates and the cost of replacing wear parts.
