A continuous cold-blade surface smooth, regular shape, high precision, is conducive to material handling, reduce material damage spiral blade mold, improve transportation efficiency. Second, the continuous cold rolling blade spiral blade is easy to install, can improve productivity and reduce production costs. Third, the continuous cold rolling leaf through online physical and chemical surface treatment, antirust ability to improve, improve the appearance of quality screw conveyor. Fourth, the continuous cold rolling blade after cold rolling surface work hardening spiral blade production, hardness and wear resistance increased by about double. Auger blade is widely used in a variety of rice and wheat combine harvesting machinery and all kinds of food machinery, material handling equipment. This product is made of imported high-quality steel, rolling from the plane through imports. And according to the needs of users, processing of different diameter, different diameter, different sub-pitch helical blade, auger blades of different lengths. The product has a smooth surface, the intensity increased, economic and durable. A variety of harvesting machinery, food machinery, chip carriage machine, mining equipment superbly good choice.
