01The role of a twin-shaft shredder knife
Zato’s Blue Devil range is an example of a low-speed, high-torque twin-shaft shredder and pre-shredder. Its counter-rotating cutting shafts reduce scrap for subsequent processing. This operating principle explains why appearance alone cannot determine a replacement: the cutting profile, mounting interface and blade arrangement need to be considered together.
02Individual blade and assembled set
The individual-part view shows machined faces, holes and channels; the assembled view illustrates how the components sit relative to one another. The visual model explains that relationship. The required component, orientation and quantity are established from a technical drawing or an existing sample when defining the order.
03Information for a manufacturing quotation
Send the exact machine model, any part reference, a dimensioned drawing, shaft and mounting details, and the required quantity. Describe the scrap being processed, wear or breakage on the existing knife and operating conditions. Material, heat treatment, hardness, cutting geometry and acceptance criteria are established from these details during drawing approval.
