Irregular Shape spiral blade

The Irregular Shape Spiral Blade is a uniquely designed component tailored for specialized applications. Constructed from durable materials, this non-standard shaped blade is engineered to fit into irregular or unconventional systems. Despite its unique shape, it maintains efficient material flow and is easy to install. This spiral blade is a testament to our commitment to innovation and adaptability in meeting diverse operational needs.

Technical details about the construction of the Irregular Shape Spiral Blade

Core Component: The spiral blade is the core component of the screw conveyor, which is a helical metal sheet fixed on the conveying shaft.

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.

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.

Efficiency: 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.

Fabrication Process: A novel conical roll-twist-bending (RTB) process is proposed to fabricate a metallic Archimedes spiral blade which has variable curvatures on its surface1. The RTB system consists of a pair of conical rollers (upper and lower sides) and cylindrical twist-bending rollers in the both lateral sides.
