Tapered Inner Screw Flight (Internal Conical Spiral Blade)

Product Overview

Tapered Inner Screw Flights feature a conical inner bore design that progressively changes diameter along the shaft axis. These specialized spiral blades are engineered for applications requiring controlled material compression, precise feeding, or variable flow rates in constrained spaces. The unique internal taper geometry enables optimized material handling in compact equipment configurations.

Key Features

1. Precision Tapered Bore - Gradually decreasing/increasing inner diameter

2. Space-Saving Design - Compact profile for equipment with limited installation space

3. Material Flow Control - Regulates feed rate and material compression

4. Heavy-Duty Construction - Available in carbon steel, stainless steel, or wear-resistant alloys

5. Balanced Configuration - Computer-optimized design for vibration-free operation

6. Customizable Geometry - Adjustable taper angles and pitch configurations
