1. Constituent part:
（1）Forming machine: making the material bend and initial machine-shaping, meanwhile, it will bend the material to the silo required radius of curvature.
（2）Bending machine: it will roll cooperate with good molding materials bender seaming together
（3）Load bearing support: Given the right diameter of silo. Lifting of the steel silo enclose the top of load bearing support rollers, it can support the spiral rising silo.
（4）Decoiler: Moving steel coils that put on the decoiler, making steel coils can into forming machine successfully.
（5）Join frame: Joining the load bearing support, locking the required diameter of soil, making the load bearing support stable working.
