Wood chipper: chips too big, knife flies dull, counter knife gap wrong
Sawmills, biomass yards, and small wood plants: chipper knife and counter knife/anvil pairing is ordinary maintenance—but wrong bolts or thickness stops production.
Typical field problems
- •You bought a “similar” blade; bolt holes almost fit but you are filing on site.
- •Counter knife wears faster than rotor; you only replaced one side and chip quality fell.
- •Seasonal wood hardness changed; edges chip sooner in dry summer stock.
Wood lines are straight mechanical fit problems: thickness, bolt circle, and counter clearance. We work like a parts supplier with a workshop—drawings help; good photos with scale still let us start.
Dealers: ask for the end user’s pocket photo once; it saves one wrong shipment.
We do not promise fantasy hours-in-wood; we align steel to your tree mix as you describe it.
