Patterson Kelley Twin-Shell Blender

Overview

The Patterson Kelley Twin-Shell Blender is an industrial batch blender engineered for gentle, uniform, and efficient mixing of dry powders, granules, and bulk solids. Its signature V-shaped twin-shell design creates a tumbling action that achieves homogeneous blends while minimizing shear.

At HiTechTrader, we provide laboratories, pilot plants, and production facilities with access to reliable Patterson Kelley Twin-Shell Blenders. Each unit is carefully inspected, refurbished, and performance-tested, offering a cost-effective blending solution backed by warranty and technical support.

4. Some models feature jacketed shells for temperature control or intensifier bars for liquid-solid blending
5. Mounted on robust steel frames or legs, with optional casters for mobility

Closure and Sealing

1. Large feed ports with covers ensure secure and efficient loading
2. Bottom discharge valves (butterfly or wafer-type) enable complete product evacuation
3. Sealed covers minimize contamination and prevent material loss
