Spiral blade

Introduction

entities helicoid screw conveyor with a helical screw face and the blade face three forms.

cold rolling mill

cold rolling mill is a continuous steel strip rolling blade advanced equipment, by adjusting its parts (roll shifting, the height of feed, pressure grinding roll, guide regulating wheel, etc.), the blade can be rolled out of a variety of needs.

The method of manufacturing a blade

The method for producing domestic blade has: a one-piece stamping and welding molding, extrusion molding, winding molding, cold forming and other methods.

The advantages of cold forming

with high efficiency, saving raw materials, good blade mass, high hardness, and good abrasion resistance. Factors roll forming

impact with the material and thickness of the strip, offset size rolls, feeding height, different grinding pressure rollers, guide wheels, and the rolling blade specification process, the roll temperature was raised, and many other factors. After years of efforts, developed such a continuous cold-rolling helical blade having a smooth surface, high hardness, wear, a shape, like a continuous weld without advantages.

Applications

helical blade is mainly used to transport large viscosity and compressibility material, such spiral face, during the transport operation is completed, while having a stirring of the material and complete , mix and more.
