Small biofuel pellet making machine Faults You Should Know
content
Common malfunctions of small wood fuel pellet making machines (daily output 1-3 tons) for beginners are mostly caused by operational errors. Mastering basic troubleshooting methods can quickly resolve these issues.
Category 1: Loose pellets that crumble easily when squeezed. This is most common among beginners and is often due to improper raw material moisture content or incorrect adjustment of the pressure roller gap. **Solution:** Use the "squeezes together in your hand, crumbles easily when released" test to determine the moisture content. If too dry, spray a small amount of water; if too wet, spread them out to dry. Insert a thin iron sheet between the pressure roller and the mold, adjusting the bolt until the sheet can be pulled but with resistance (gap 0.2-0.3mm)
Category 2: No material feeds after equipment startup. The symptom is that after starting the equipment, there is no change in the raw material at the feed inlet, preventing it from entering the pressing chamber. Causes: Common mistakes made by beginners include "feeding without preheating," "feeding too quickly causing blockage," and "residual lumps at the feed inlet." Solutions: First, stop the machine and disconnect the power; clean any residual lumps at the feed inlet; start the equipment and run it idle for 3-5 minutes to preheat, then slowly add raw material; reduce the feed speed and avoid adding material all at once.
Category 3: Motor trips and cannot be restarted. The symptom is a sudden tripping of the circuit breaker during operation of the small biomass pellet maker machine, which fails to restart after being reset. Causes: Overloading due to excessive feed, triggering motor thermal protection; dust clogging the motor's heat dissipation vents, causing overheating protection; unstable power supply voltage. Solutions: Clean excess material from the feed inlet and reduce the feed rate; clean dust from the motor's heat dissipation vents and allow the motor to cool down (approximately 30 minutes); check the household circuit voltage and avoid simultaneously operating other high-power appliances.
Category 4: Inconsistent pellet length in the finished product. The symptom is a large difference in pellet length, affecting storage and use. Causes: Inexperienced operators have not adjusted the cutter position, or the cutter is loose. Solutions: After stopping the machine, adjust the distance between the cutter and the mold, ideally to 2-3 times the pellet length in diameter; tighten the cutter fixing bolts to ensure they do not loosen during operation; if the cutter becomes dull, lightly sharpen it with a whetstone.
Category 5: Abnormal noises during operation of the small biomass pellet maker machine for home use. The symptom is a "clicking" or "squeaking" sound during operation. Causes: Impurities such as small stones and nails in the raw material; insufficient lubrication in the bearings. Solutions: Immediately stop the machine, clean the impurities from the raw material, and check the cleanliness of the raw material; add a small amount of high-temperature grease to the bearings (beginners can use general-purpose lithium-based grease).
Tips for beginners: Preheat the machine by idling before starting; feed materials in small amounts multiple times; regularly clean any residue from the equipment; check the condition of the pressure rollers and dies after each production run to prevent small problems from escalating.
