How Do Operating Habits Affect the Lifespan of a Biomass Briquette Extruder Machine?

Specific factors

★Proper preheating and startup procedures are fundamental to extending the lifespan of a wood dust charcoal briquetting machine

Many early failures of wood dust charcoal briquetting machines are not due to quality issues, but rather improper operation. Preheating before feeding is essential; this is the most basic yet crucial operating procedure. Forcing feeding before the operating temperature is reached results in insufficient plasticization of the raw material, extremely high resistance, and a high risk of screw jamming, motor overload, and sleeve damage. The standard startup procedure is: first, turn on the heater and preheat for 20–30 minutes; then start the main unit and let it idle for 1–2 minutes; finally, gradually feed small amounts of material, observing the output status to ensure it is normal before increasing production. Strictly adhering to this procedure can prevent the vast majority of startup failures.

★Overloading and prolonged continuous operation are strictly prohibited

Overloading is the most common cause of shortened lifespan for wood charcoal briquette press machines. Forcing a higher feed rate in pursuit of output will subject the motor, bearings, and screw to high stress for extended periods, accelerating metal fatigue and wear. It is recommended to stop the equipment for 30 minutes after 8-10 hours of continuous operation to allow the motor, bearings, and heating coils to cool down appropriately and reduce high-temperature aging. Stable and uniform production is far more beneficial for extending equipment life than short-term high-load production.

★Proper shutdown and cleaning procedures prevent damage during subsequent startups

Incorrect shutdown can also damage the biomass briquette press machine. The correct procedure is: first, stop feeding, let the main unit idle, and completely discharge any remaining material from the sleeve; then, turn off the heating, and finally, shut down the machine. If the power is cut off directly, the residual material will cool and solidify inside the sleeve, easily causing serious malfunctions such as jamming, motor burnout, and broken screws during the next startup. Simply cleaning the feed inlet and surface dust after shutdown can significantly reduce the risk during the next startup.
