Screw Blade

Introduction The screw blade is the core component of the screw conveyor, which is a helical metal sheet fixed on the conveying shaft. The main function of the spiral blade is to push the material from the input end to the output end during the rotation of the shaft, so as to realize the continuous conveying of the material. The design and manufacture of the screw blade directly affects the performance and efficiency of the conveyor. Design factors for spiral blades include: Material: The spiral blade is usually made of stainless steel, carbon steel or other wear-resistant materials to ensure its good performance in long-term operation. Pitch: The pitch is the distance between two adjacent turns on the helical blade, which will affect the conveying capacity and efficiency. The choice of screw pitch needs to be determined according to the characteristics of the material to be conveyed. Blade Width: The blade width determines the conveying capacity of the conveyor. When choosing the blade width, factors such as the volume and density of the material need to be considered. Blade Thickness: Blade thickness affects the strength and durability of the propeller blade. Choose the appropriate blade thickness according to the wear degree of the material and the service life requirements of the equipment. Screw conveyors and their helical blades are widely used in many industries such as agriculture, chemical industry, mining, construction, food processing and environmental protection. As the key component of the screw conveyor, the screw blade has many advantages, such as high efficiency, compact structure, strong adaptability, low energy consumption and low noise. Design factors include material, pitch, blade width and blade thickness.
