Worm blades (also known as screw flights or auger blades) are mechanical components designed to transport, mix, or feed materials in industrial systems. These blades are mounted on a rotating shaft and form a spiral (helical) structure that pushes material forward during rotation.
They are widely used in industries such as agriculture, flour mills (chakki), cement, food processing, and packaging. The blades can be manufactured from mild steel, stainless steel, or wear-resistant alloys, depending on the application and material being handled.
