MILL WITH QUICK CHANGE, UNITIZED, DYNAMIC ELEMENTS

摘要

A mill with capability for rapid replacement of wearable moving components and capacity for precision grinding movement. The wearable moving components form a package of dual counter-rotating rotor centrifugal devices, the package including first and second motors (2, 5), counter-rotating first and second rotors (1, 4) driven by the first and second motors, respectively, a hollow shaft (6) connecting the first motor to the first rotor, and a solid shaft (3) connecting the second motor to the second rotor, the solid shaft running inside the hollow shaft.
