Conical spiral blade
- There are three forms of conical spiral blades: solid spiral surface, belt spiral surface, and blade spiral surface. Among them, blade spiral surface is relatively less commonly used, mainly for conveying materials with high viscosity and compressibility. This spiral suspension surface type has the function of mixing and blending materials during the conveying operation.
Cold rolling mill is an advanced equipment for continuously rolling blades with strip steel. It can roll various specifications of blades required by adjusting the parts (roll offset, feeding height, rolling pressure, guide wheels, etc.). At present, there are various methods for manufacturing blades in China, including single piece stamping and welding, extrusion forming, winding forming, and cold rolling forming.
Jiangsu Kuangji Industrial Technology Co., Ltd. as a spiral bladeProduction Base in East China RegionSelecting premium brands(High quality steel such as carbon steel, alloy structural steel, 304 stainless steel, 316L stainless steel, etc.)Continuous blade cold rolling once forming, uniform pitch, no cracks, equal thickness blade stamping forming(Special hydraulic press)Mature technology(Heating temperature balance, plasma cutting, laser cutting, smooth surface, high hardness, wear resistance)The production plate thickness can reach 60MM, and the maximum outer diameter can reach 1600MM.
