Tapered Outer Screw Flight (Conical Spiral Blade)

Product Overview

The Tapered Outer Screw Flight is a specialized conveying component featuring a conical outer profile that gradually changes diameter along its length. This unique design enables controlled material flow in applications requiring variable compression, expansion, or precise material distribution. Our precision-engineered conical spiral blades are manufactured to exacting standards for superior performance in demanding industrial processes.

Key Features

1. Gradual Diameter Transition - Smoothly tapered profile from large to small diameter (or vice versa)

2. Precision-Formed Geometry - CNC-machined for consistent pitch and optimal material flow

3. Heavy-Duty Construction - Available in carbon steel, stainless steel, and wear-resistant alloys

4. Variable Pitch Options - Customizable to match specific process requirements

5. Wear-Resistant Solutions - Hardfacing, ceramic coatings, or replaceable wear segments

6. Balanced Design - Engineered for vibration-free operation at various speeds
