They are the rotor discs to which the blades are connected in SHREDDER Crushers. It is very important that these parts in crushers are produced using precise and correct material. Since the hooks and blades are connected on this part, all surfaces and dimensions must be precisely machined and ground. This part, which has different variations according to the rotor dimensions and the type of blade used, should be in a structure that should be able to absorb impact and be resistant to abrasion. Rotor discs, which can be produced with many different materials, are products that must be carefully heat treated and NDT inspected after processing. It can also be produced using ductile iron casting material upon customer request.
