Stainless steel screw conveyor has a compact structure, small cross-sectional area, light weight, good sealing performance, high transmission efficiency, flexible process layout, installation, disassembly, easy movement, safe operation. It is not easy to produce corrosion, pitting, corrosion or wear. There are two forms of horizontal or inclined delivery. There is a discharge valve at the lower end of the feed inlet, and the screw can be reversed, so the discharge and cleaning are very convenient. Stainless steel screw conveyor mainly has the advantages of acid resistance, alkali resistance, high temperature resistance or low temperature resistance, wear resistance, not easy to rust, and not easy to contaminate materials. Its material can be 304, 316L, 321, or some special occasions use titanium steel and other materials. According to different fields of use choose the right stainless steel material.
