Impact 1: Screw Wear Leads to Uneven Particle Size, Looseness, and Fragility
The screw of the twin screw pet food making machine is the core component for extruding and maturing materials. Insufficient daily maintenance (such as failure to clean and lubricate regularly, and failure to replace worn parts in a timely manner) will lead to screw surface wear and pitch deformation, thus affecting the extrusion force and maturation uniformity of the material. Actual test data shows that after screw wear exceeds 12μm/3000 hours, if maintenance and replacement are not carried out in time, the particle size error will increase from ≤±0.2mm to over ±0.5mm, resulting in a large number of excessively large and small particles. Simultaneously, insufficient extrusion force leads to incomplete maturation of the material, resulting in a loose internal structure of the particles, making them fragile and prone to collapse. Water resistance is shortened from 4-6 hours to 1-2 hours, causing rapid dissolution in water, making them unsuitable for fish consumption and resulting in feed waste.
Impact 2: Die Head Blockage/Wear Leads to Abnormal Particle Forming and Rough Surface
The die head is a key component in particle forming. Insufficient daily maintenance can lead to residual mold and impurity accumulation, causing die head blockage or uneven wear. If the die head of a floating fish feed pellet making machine is clogged and not cleaned in time, problems such as poor discharge, broken pellets, and deformities will occur, reducing the pellet quality rate from over 98% to below 70%. Uneven die head wear will result in a rough, dull pellet surface, with some pellets developing burrs and dents, which not only affects fish feeding but also reduces the pellets' water resistance and stability. Furthermore, improper die head maintenance can lead to fluctuations in discharge pressure, further exacerbating pellet formation problems.
Authoritative Improvement Recommendations: Precise Maintenance, Avoiding Forming Hazards
After daily production, clean the screw and die head of any residual material, rinse with warm water, dry, and apply rust-preventive oil to prevent wear and mold. Check the screw and die head of the small fish food pellet making machine weekly for wear; repair minor wear promptly, and replace severely worn parts (exceeding the rated wear limit) immediately. Calibrate the die head aperture monthly to ensure uniformity and check the die head sealing performance to prevent discharge leakage. By performing the above routine maintenance, the pellet forming qualification rate can be maintained at over 98%, effectively avoiding the impact of insufficient maintenance on forming quality, and extending the service life of the extruder.
