What are the advantages of the overall internal structure of the metal wood shredder? The main body of wood shredding machine adopts high quality steel plate welding to eliminate stress treatment/whole machine processing, so as to ensure the stability of equipment in long time heavy load. 2. Using the knife knife/sword materials using special special alloy tool steel forging blank, precision machining, heat treatment and cold heat treatment technology, the overall hardness toughness consistent repeat repair can be used, to ensure that the cutting performance and service life. The fixed knife adopts patent hook type installation, optimizing tool replacement function, making tool maintenance and replacement more efficient. 3. Bearing/seal bearing adopts patent split and split type, can quickly remove the moving knife, knife, bearing parts, easy maintenance and replacement of cutting tools, special seal structure effectively block gouge and grease contact, deal with liquid material also can protect the bearings and gears, etc. 4. The cutter shaft is made of special steel with high strength and heavy duty, and it is more reasonable to cooperate with the cutter to provide powerful driving force for cutting.
