Ф45mm-Ф250mm
Length/Diameter Ratio：L/D：4-6
Surface WC/CO overall spray welding can effectively improve the service life of the screw. The use of two-head or three-head thread feeding section is more conducive to the feeding of rubber powder, and the use of a thread opening groove to promote the homogenization of materials, such as butyl rubber, natural rubber, nitrile rubber, styrene-butadiene rubber.
