What to Do When a Fuel Pellet Machine Does Not Produce Pellets
Why Output Drops or Stops Completely
When a fuel pellet machine produces no pellets, or the output is very low and much of the material comes out as powder, the cause is usually in the preparation of the pressing parts. The most common reason is that the press wheel and the grinding disk were not polished well during the break-in process of the machine. A similar problem can appear when the grinding holes in the grinding disk were not fully polished at the first use. Although this problem does not occur often, it indicates that the contact surfaces between the pressing parts and the die are not yet smooth enough to form pellets reliably.
Polish the Press Wheel and the Grinding Disk
The normal solution is to continue the break-in procedure. Run abrasive material through the machine so that the grinding disk is sharpened, or simply continue using the machine for a period of time. Once the grinding disk has been sharpened and the contact surfaces have worn in evenly, the output of the machine returns to the normal level. Be patient with the break-in period and do not increase the load excessively, because the forming quality improves as the surfaces become fully matched.
Control the Moisture Content of the Raw Material
Moisture control also has a direct influence on output. If the moisture content of the processed raw material is not well controlled, the output of the machine drops and the pellet quality becomes unstable. The moisture in the raw material should be controlled at 13% to 20%. Keep the raw material storage area dry, and check the moisture level before each production run so that the pressing conditions remain consistent throughout the day.
Handle Freshly Pressed Pellets Correctly
The handling of the finished material also affects the final result. The biomass fuel pellets pressed out by the machine can be bagged after 5 to 10 minutes of shade drying at room temperature. This short drying step lets the pellet surface set and reduces the risk of breakage and mold during storage. Avoid immediate bagging of hot or wet pellets, and keep the bags in a dry, ventilated place so that the moisture content stays within the safe range.
FAQ
Q1. Why did my machine produce no pellets at the beginning?
The most common cause is that the press wheel and the grinding disk were not polished well during the break-in process, so the pressing surfaces are not yet smooth enough.
Q2. How can I restore normal output?
Run abrasive material through the machine to sharpen the grinding disk, or continue using the machine for a period of time until the surfaces wear in evenly.
Q3. What moisture content should the raw material have?
The moisture in the raw material should be controlled at 13% to 20%.
Q4. When should fresh pellets be bagged?
The pellets can be bagged after 5 to 10 minutes of shade drying at room temperature.
Q5. Can raw material moisture affect the output?
Yes. Poorly controlled moisture lowers the output and makes the pellet quality unstable.
Q6. What should I do if the output remains low after polishing?
Check the moisture content of the raw material first, and confirm that the grinding holes of the disk have been fully sharpened before adjusting other parameters.
