Floating Fish Feed Extruder Machine Lifespan Explained

Replacement standards for core wear parts: Accurately assess the degree of wear. The ring die, as a core component of the floating feed making machine, needs to be replaced when the following conditions occur: the bore wear exceeds 0.2mm, resulting in excessive particle size deviation (>±0.5mm); cracks or deformation appear on the ring die surface, or the feed hole is blocked by more than 30% and cannot be cleaned; the ring die's service life reaches 8000-12000 hours (processing soft materials) or 4000-6000 hours (processing hard materials). The pressure roller needs to be replaced when surface wear and indentation exceed 0.5mm, rotation is not smooth, or the bearing is damaged. The replacement cycle is typically 1.5-2 times that of the ring die.

Replacement standards for auxiliary wear parts: Avoid cascading losses. The cutter needs to be replaced when the blade wears down, the pellet cutting length deviation exceeds ±1mm, or the rotation speed is unstable. It should be calibrated monthly and replaced every 3-6 months. Bearings and gears need to be replaced when abnormal noise, increased vibration, or decreased transmission efficiency occur; their lifespan under normal use is approximately 2-3 years. Seals need to be replaced promptly when material leakage or lubricant leakage occurs, especially those at the connection points with the sinking fish feed extruder machine, as these come into contact with high-temperature materials and should be replaced every 1-2 months. When replacing seals, the sealing of the extruder outlet must be checked simultaneously to prevent high-temperature material leakage and corrosion of pellet mill components.

The linkage logic for replacement with the extruder is as follows. When replacing the screw and barrel of a sinking fish feed making machine, the wear condition of the pellet mill's ring die and pressure rollers must be checked simultaneously. Worn parts in the extruder can lead to uneven output and impurities in the material, accelerating wear on pellet mill components. Replace vulnerable pellet mill parts in advance if necessary. After replacing the ring die and pressure rollers in a mini fish feed machine, the feed speed and extruder output parameters must be calibrated to ensure they are compatible and avoid load fluctuations. Furthermore, a parts replacement log should be established to record the usage time and wear condition of pellet mill and extruder parts. Following the principle of "anticipating problems and replacing parts promptly," equipment failures caused by component aging should be avoided, ensuring the overall machine lifespan.
