When processing coarse-fiber materials such as straw, grass clippings, and vines with a new type two in one organic fertilizer granualtor, it is necessary to control four aspects: raw material pretreatment, equipment parameters, operating conditions, and daily protection to ensure stable molding and reduce equipment wear.

First, ensure proper raw material pretreatment. Crush and cut the coarse-fiber materials in advance, controlling the fiber length to no more than 8 mm. Remove stones, hard metal pieces, and other impurities to prevent damage to the rollers and blades. Appropriately mix and blend sticky raw materials such as manure and humus, ensuring the coarse fiber content is not too high to avoid loose materials that are difficult to clump together. Strictly control moisture content, maintaining it between 22% and 28%. Too low a moisture content makes extrusion molding difficult, while too high a moisture content can cause sticking and blockage of the mold.

Second, adjust the operating parameters of the fertilizer production machine. Appropriately reduce the equipment's travel and extrusion speeds to decrease the probability of fiber entanglement caused by high-speed pulling. Fine-tune the roller gap appropriately, matching the extrusion force to the material's uniformity to avoid machine stalling due to insufficient gap. Increase the feed opening appropriately to ensure smooth and uniform material feeding, preventing localized material accumulation and entanglement on the rollers.

Standardize on-site operation procedures, maintaining uniform and continuous feeding, and strictly prohibiting sudden, large-volume feeding. Monitor the discharge status during operation; if fiber entanglement is found on the die rollers, immediately stop the machine for cleaning, and do not force operation. Reduce frequent start-ups and shutdowns to avoid fiber jamming and impact on transmission bearings and gear components.

Finally, strengthen equipment protection and maintenance. Regularly clean entangled fiber debris from the die holes to maintain permeability. Periodically check the wear of blades and pressure rollers, and repair or replace worn parts promptly. Add lubricating grease daily, tighten loose connections, reduce mechanical wear caused by coarse fiber friction, and improve pellet forming yield and equipment lifespan.
