How to solve common faults in the mixing equipment of a fish feed pellet production line?

There are four main types of common malfunctions in mixing equipment, requiring precise identification and resolution of the causes. The first type is substandard mixing uniformity, manifested as uneven nutrient distribution in the feed. Core causes include insufficient mixing time, worn agitator, excessively high raw material moisture content (>20%), or significant particle size differences. Solutions include: resetting the mixing time according to the type of raw material; replacing worn agitator blades promptly (alloy blades typically have a lifespan of 1500-2000 hours); controlling raw material moisture content to 8%-18%; and for raw materials with large particle size differences, first grinding them to similar particle sizes before mixing. One feed mill experienced uneven mixing due to a large difference in particle size between cornmeal and fishmeal; after grinding the cornmeal to 100 mesh, the mixing uniformity (CV) decreased from 12% to 4%.

 

The second type is excessive noise (over 85 decibels) from the Floating Fish Feed Extruder Line. Causes include unbalanced agitator, insufficient bearing lubrication, and excessive feed rate causing blockage.Solutions: After shutdown, adjust the balance of the mixing device, add food-grade lubricating oil to the bearings (once a month), and strictly control the feed rate to avoid exceeding 10% of the equipment's rated capacity. If the noise comes from the gearbox, check the gear wear; if the wear is severe, repair or replace the gears.

 

The third type is floating fish feed production line issues such as poor discharge or excessive residue. Causes include outlet blockage, material buildup on the mixing chamber wall, and excessive clearance between the agitator and the chamber wall. Solutions: Regularly clean residual material from the outlet; after producing high-viscosity material, rinse the mixing chamber wall with warm water; adjust the clearance between the agitator and the chamber wall (controlling it to 5-10mm); if the clearance is too large, replace the agitator blades or adjust the equipment structure.

 

The fourth type is fish feed processing line issues such as motor overheating and shutdown. Causes include motor overload, blocked cooling vents, and unstable voltage. Solutions: Reduce the feed rate, ensure the motor load does not exceed 90% of its rated power, regularly clean dust from the motor cooling vents, and install a voltage stabilizer to ensure stable voltage (380V±5%). If the motor frequently overheats, check for jamming in the agitator and eliminate the blockage promptly.

 

Daily maintenance should establish a "three-level maintenance" system. Level 1 Maintenance (Daily): Before starting the machine, check that all connections of the equipment are secure. After starting, observe the operating status. After stopping, clean the mixing chamber and feed inlet of any residue and record the equipment operating parameters. Level 2 Maintenance (Weekly): Check the wear of the mixing blades and screw rod. Add lubricating oil to the bearings and gearbox. Calibrate the mixing time and speed parameters. Level 3 Maintenance (Monthly): Completely disassemble the equipment, check the wear and corrosion of internal components, replace aged seals, and polish the inner wall of the mixing chamber to ensure a smooth, dead-angle-free surface. In addition, an equipment maintenance log should be established to record the content of each maintenance and the handling of any malfunctions. This provides a basis for equipment lifespan management. With proper maintenance, a high-quality mixing equipment can have a service life of 8-10 years.

 

 

 

 

 

MIKIM's fish feed pellet production lines and supporting machinery offer excellent value for money. Not only are they affordable, eliminating middlemen markups and allowing small and medium-sized enterprises (SMEs) and fish farmers to purchase complete sets of equipment at reasonable costs, but they also boast exceptional efficiency. The fully automated process, from raw material crushing and precise ingredient mixing to extrusion pelleting and maturation, is completed in one continuous flow. This results in high starch gelatinization rates and uniform pellet formation, significantly improving production efficiency and feed quality, truly achieving "low cost, high output." Choosing a MIKIM fish feed pellet production line means enjoying comprehensive pre-sales and after-sales service, including 24-hour online customer support, a one-year warranty on the entire machine, professional on-site installation, commissioning, and maintenance, and a stable supply of spare parts. Customers can buy with confidence and use with peace of mind, with both excellent value and service quality!
