Unternehmensnachrichten über Fish Feed Processing Machine Buying and Operating Essentials

The core procedures and frequency for daily maintenance of a floating fish extruder machine are as follows: A standardized maintenance log should be established, and maintenance should be implemented according to the frequency: First, daily maintenance: After production, stop the machine to cool it down, clean the residual raw materials in the extrusion chamber, die, and feed hopper of the extruder to prevent drying and corrosion of parts; wipe off oil and dust from the equipment surface, check for leaks in the seals, and add lubricating oil to the specified level; check the die orifice for blockages or wear, and clean or grind it promptly. Second, weekly maintenance: Disassemble the extruder screw and bearings, clean the surface carbon and wear residue, and add high-temperature grease; check for loose joints in oil pipes and steam pipes, and tighten the connections; clean scale from the cooling system to improve heat dissipation efficiency. Third, monthly maintenance: Check the wear of the screw threads and die sealing surfaces, measure the wear amount, and repair or replace those exceeding the standard promptly; check the electrical control system, clean the wiring for dust, and ensure accurate parameter control.

Key points for replacing core vulnerable parts and selection techniques. The main wear parts of an extruder include the screw, die, oil seal, and bearings. Replacement should follow the principle of "precise selection and standardized installation": First, for the screw and die, select original factory parts matching the equipment model. Nitrogen-plated steel is preferred for the screw, and wear-resistant alloy steel for the die. After replacement, parameters need to be adjusted to ensure extrusion effect. If wear is minor, it can be repaired by grinding to extend service life. Second, for oil seals and sealing components, select high-temperature and oil-resistant types (fluororubber material, temperature resistance ≥180℃). When replacing, clean the sealing groove, apply grease to ensure a tight seal and prevent oil leakage from contaminating the feed. Third, for bearings, select high-precision wear-resistant bearings. After replacement, check the rotation flexibility and add appropriate grease to ensure smooth screw operation. For flat/ring die machines, focus on replacing the pressure roller and die to avoid poor pellet formation due to wear.

Key points for maintenance and use of dry-type fish feed pellet processing machines. Maintenance needs to be dynamically adjusted based on the equipment's operating status: if abnormal noises or increased vibrations occur during extruder operation, it may indicate bearing wear or a loose screw, requiring immediate shutdown and inspection; if the feed breakage rate increases or the extrusion degree fluctuates significantly, it may indicate die head wear, requiring timely replacement. Simultaneously, avoid overloading the equipment; the extruder's continuous operating time should not exceed 8 hours, with a 30-minute cooling stop in between to reduce component wear. Through a "daily maintenance + condition monitoring" model, equipment downtime due to malfunctions can be reduced from 8 hours per month to less than 2 hours, significantly improving production efficiency.
