China Helicoid Flight

Sectional Screw Flight
Commonly Used Material: Carbon steel, Alloy steel, Manganese Steel, Stainless Steel, Wear-resistant Steel.
Specification: Customized according to customer demand, the maximum diameter of 1800mm, the maximum thickness of 30mm.
Production process: mold cold forming.
Advantages: Produced by cold forming technology, ensure from the physical properties of raw material. effectively guarantee its inner diameter, pitch, helical surface in prime line perpendicular angle;
Large diameter, large thickness, high pitch; spiral smoothing,
perfect spiral opening angle, plain helical surface and in line completely vertical.
Usage: suitable for mining, chemical industry, agriculture, environmental protection and construction of pile foundation engineering and other industries.
Product function: Segmentation and other thick spiral blades on the screw conveyor, mixers, hammers, drilling machinery and other equipment, material handling and screw driving beneficial, can effectively improve the efficiency of the device.
