How to Prevent homemade wood sawdust pellet machine from Suddenly Stopping Rotating?

 

 

First, standardizing raw material pretreatment is crucial to reduce the risk of malfunctions at the source. Raw materials are a major cause of overload and die blockage, so three standards must be met: 1) Moisture content must meet the standard (12%-15%), using a simple moisture meter to prevent high- or low-moisture raw materials from entering the equipment; 2) Particle size must meet the standard (2-5mm), employing two-stage crushing and grading sieves to ensure uniform particle size and eliminate large pieces of raw material; 3) Thorough impurity removal must be achieved through a three-stage impurity removal system: a vibrating screen for initial screening, a magnetic separator for fine screening, and manual sorting, resolutely removing hard impurities such as nails, stones, and sand. Daily records of raw material batch information must be kept, and pretreatment parameters must be readjusted if the type of raw material is changed.

 

Second, daily maintenance of the domestic wood pellet machine is essential, focusing on cleaning, lubrication, and inspection. Cleaning: After each production run, thoroughly clean the feed inlet, pressing chamber, die holes, and discharge outlet to prevent raw material from hardening and causing blockages in the next production run. Perform a deep cleaning weekly, removing dust and oil from the motor heat sink and gearbox surface. Lubrication: Add high-temperature grease to the pressure roller bearings every 200 hours, and change the gear oil in the gearbox every 1000 hours. When changing the oil, clean the inside of the gearbox to ensure proper lubrication. Control the amount of grease used to avoid contaminating the raw materials.

 

Regular inspection is key to preventing mechanical and electrical failures: Before starting the machine each day, check the gap between the pressure roller and the die (0.1-0.3mm), whether the anchor bolts and connecting bolts are loose, and whether the safety guard is intact. Every 500 hours of operation, check the wear of the pressure roller and die; if wear exceeds the standard, grind or replace them promptly. Every 1000 hours of operation, check the motor winding resistance of the sawdust pellet making machine, whether the electrical wiring is aging or damaged, and whether the leakage protection device is sensitive. Address any problems promptly; do not produce while faulty.

 

Standard Operating Procedures: Operators must undergo professional training and be familiar with the working principles and operating procedures of the biofuel sawdust pellet machine. Unauthorized operation is strictly prohibited. Maintain a uniform, low-speed feeding process, avoiding sudden, large feeds. The feeding speed can be precisely controlled via a frequency converter system. During equipment operation, monitor motor current, temperature, and pellet formation status in real time. If any abnormalities occur (excessive current, motor overheating, poor pellet formation), immediately stop the machine and investigate. Avoid prolonged overload operation; continuous daily operation should not exceed 8 hours, with a 1-hour break in between to allow the equipment to cool down.

 

Additional Reminders: Establish an equipment maintenance log, recording the time, content, fault details, and handling results of each maintenance session. Regularly summarize fault patterns and optimize maintenance plans accordingly. Stock commonly used consumable parts (such as pressure rollers, molds, bearings, and wires) to avoid production interruptions due to lack of spare parts in case of malfunctions.
