(1) Main drive connection flange (connecting main drive);

(2) 7J disk support (transmitting torque and axial force),

Two support methods;

(3) Outer ring beam (strengthening structural strength);

(4) Knife beam (installing cutting tools);

(5) Mixing rod (soil improvement);

(6) The entrance for good injection of slag soil (slag soil improvement);

(7) N adapter (input foam or bentonite to the panel of the cutter head and deliver hydraulic oil to the hydraulic cylinder of the overbreaker);

(8) Wear resistant layer: In addition to installing the tool, it is also necessary to weld a wear-resistant layer to protect the cutterhead body. The wear-resistant layer generally has three forms:

a. Use wear-resistant welding rods to weld wear-resistant grids or wear-resistant layers;

b. Welding hardox500 steel plate;

c. Welding wear-resistant composite steel plates.
