Improving the durability of organic fertilizer double axis mixers hinges on controlling materials, strengthening the structure, standardizing operations, and performing regular maintenance. Reducing wear, overload, and corrosion from the source can significantly extend the machine's lifespan.

Material pretreatment is crucial.  Strictly remove hard objects such as stones, metals, and films to prevent damage to the mixing shaft, blades, and gearbox. Control the moisture content to 35%-55%; excessive moisture leads to sticking and overloading, while excessive dryness increases dust and wear.  Pre-crush lumpy materials to prevent uneven stress distribution.

Operationally, it is strictly prohibited to overload the fertilizer produciton machine or force-start it with material inside.  The machine should be started empty first, then material should be added gradually to avoid sudden full load; frequent switching between forward and reverse rotation is prohibited to prevent impact damage to the transmission gears and couplings; before shutting down, stop feeding material, run the machine empty to clear any remaining material, then switch off the power and clean the machine to prevent material from drying and hardening, which could cause overload during the next startup.

A fixed maintenance schedule is essential: daily cleaning of the cylinder and blades, checking bolt tightness and seals for leaks; weekly lubrication of bearings, chains, and couplings, and checking transmission tension; monthly inspection of blade and liner wear, and correction of shaft runout; and semi-annual replacement of gear oil and hydraulic oil, and inspection of motor insulation and wiring.

Simultaneously, implement corrosion prevention measures. Components in contact with acidic organic fertilizer materials can be coated with anti-corrosion coatings. Maintain a well-ventilated and dry workshop to prevent moisture and corrosion of electrical components and bearings. Through standardized use and meticulous maintenance, the continuous operating life of the twin-shaft mixer can be significantly extended, and the failure rate and maintenance costs can be significantly reduced.
