Pellets Falling Apart Due to Moisture: Causes and Fixes
News 2026-11-03 37
Pellets that fall apart are a quality failure that shows up late. The pellet leaves the die looking intact, passes through the cooler, and then crumbles in the bag, in the conveyor, or in the customer’s boiler. By the time the complaint arrives, the material has already bee...
Pellet Mill With Mixed Materials: Blending and Selection
News 2026-11-03 35
A pellet mill running a single material is a simpler machine to specify than one running a blend, and the difference shows up in every stage of the line. Mixed materials vary in lignin, ash, moisture, particle size, and bulk density, and a blend can behave in ways that neither of...
Sawdust Too Coarse for Pelleting: Grinding and Die Fixes
News 2026-11-02 58
Sawdust that is too coarse for pelleting does not usually fail quietly. It bridges in the feeder, feeds unevenly into the die, produces soft or cracked pellets, or simply will not compact at all. Operators often respond by adding moisture or changing the die, when the real proble...
Pellet Mill for High Moisture Material: Drying and Selection
News 2026-11-02 61
High moisture material will not pellet reliably on a mill that was specified for dry feedstock, and the failure usually shows up as blocking, roller slip, blinded die holes, or soft pellets rather than as a clean capacity shortfall. The mill is rarely the first thing that needs c...
Dry Material Not Pelleting: Causes and Fixes
News 2026-11-02 44
Dry material that will not pellet is usually described as a moisture problem, and moisture is often part of it. But dry material not pelleting covers several different failures, and they do not share a single cause. A mill that produces no pellets at all, a mill that produces sof...
Wet Sawdust Clogging a Pellet Mill: Causes and Fixes
News 2026-10-31 47
Wet sawdust clogging a pellet mill is usually blamed on moisture. Often moisture is involved, but it is rarely the whole story, and treating it as the only variable is how operators end up buying a dryer that does not solve the problem. The fastest way to fix a clogged pellet mil...
Wood Pellets Won’t Form: Causes, Checks and Fixes
News 2026-10-31 43
Wood pellets that will not form usually point to a material, a die, or a machine condition that is outside the working range. An operator error, a startup procedure that is not followed, or a sensor fault can produce the same symptom, and the production record and the pelletizing...
Pellet Mill Roller Gap Too Big: Effects, Checks and Adjustment
News 2026-10-31 38
A pellet mill roller gap that is too big means the roller cannot press the material into the die holes with enough force. The gap is the distance between the roller surface and the die surface, and a gap that is larger than the machine specification reduces the compression, the p...
Pellet Die Surface Pitting: Causes, Inspection and Repair
News 2026-10-30 47
A pellet die surface that is pitting has lost small areas of material from the working surface, and the loss is different from the even wear that a die shows at the end of its life. A severe abrasion or a corrosion can produce a pitting that appears together with the wear, and th...
Pellet Mill Roller Shaft Bent: Causes, Checks and Replacement
News 2026-10-30 39
A pellet mill roller shaft that is bent is usually not a normal wear condition. A material defect or a manufacturing defect can also produce an early bend, and the shaft record and the supplier documentation separate the service bend from the defect bend. The shaft is designed to...
Pellet Die Hole Deformation: Causes, Checks and Replacement
News 2026-10-30 48
A pellet die hole that has deformed is usually not the same problem as a hole that is blocked. A blocked hole is filled with material, and the geometry is unchanged. A deformed hole has changed shape, and the change affects the compression, the pellet quality, and the die life. A...
Pellet Mill Roller Bearing Failure: Causes and Checks
News 2026-10-29 52
A pellet mill roller bearing that has failed is usually the last item in a chain that started earlier. A bearing manufacturing defect, a sudden impact, and a seal failure can also produce a sudden failure, and the failure mode and the bearing record separate the chain failure fro...
