After each shift, it is essential to thoroughly clean the blades and shaft to remove any wet material and clumps of fertilizer sludge. Long-term adhesion of sticky materials increases the operating load, accelerates blade wear, and can easily cause feed blockage and motor overload. Avoid striking the blades with hard objects during cleaning to prevent chipping or curling.

During operation, conduct regular inspections to observe the blade's operating status. Increased equipment vibration, uneven output particle size, and decreased granulation rate are often caused by worn or loose blades. If a single set of blades is found to be loose, immediately stop the machine and tighten the bolts. If the blade edge becomes thin and rounded, it can be flipped for use depending on the degree of wear. If both sides are worn, replace the entire set immediately to ensure that all blades experience consistent force and impact.

For raw materials containing a large amount of straw and vines, pre-cutting is necessary to reduce the entanglement and pulling of long fibers on the blades, thus minimizing abnormal wear. Raw materials must be equipped with impurity removal devices; stones or hard metal objects entering the cavity can easily crack or break the blades, causing safety malfunctions.

Lubrication and protection are also crucial. The blade spindle bearings and connecting bushings should be lubricated periodically to prevent dust intrusion and jamming. During long-term shutdowns in the off-season, clean the material from the blade surface, apply anti-rust grease, and store in a dry environment to prevent moisture and corrosion.

It is recommended to conduct a comprehensive inspection of blade wear and tightness every two weeks, and sharpen or replace as needed. Proper maintenance not only reduces replacement costs but also ensures the fineness of material grinding, allowing for the continuous and stable operation of the subsequent bio-organic fertilizer granulation process.
