Twin Shaft Mixer
Twin Shaft Mixer Overview
Powerful, Precise, and Versatile Mixing for Heavy-Duty Applications
The Twin Shaft Mixer is engineered for high-efficiency blending of challenging materials, especially in industries requiring robust handling of semi-solid, viscous, or abrasive components. Designed with two counter-rotating shafts equipped with specially configured paddles or blades, this mixer delivers superior homogeneity in short cycle times—making it ideal for applications in chemicals, construction adhesives, ceramics, and more.
Working Principle
The Twin Shaft Mixer operates using two horizontal shafts equipped with specially designed paddles or blades that rotate in opposite directions. As the shafts turn, they generate an overlapping counter-current flow pattern, ensuring thorough mixing of materials throughout the vessel.
The counter-rotating action lifts, folds, and disperses the material, breaking up clumps and promoting uniform distribution. This dynamic movement allows for rapid and homogeneous blending, even with heavy, sticky, or abrasive components.
In some models, liquid can be sprayed during mixing for wet granulation or paste formation. Once the desired consistency is achieved, the mixture is discharged through a bottom or side outlet—designed for quick, complete emptying with minimal residue.
Key Features
Dual Shaft Counter-Rotating Blades: Ensures rapid and uniform mixing with overlapping flow patterns.
High Torque Capability: Suitable for mixing heavy, dense, or highly viscous materials.
Customizable Design: Available in various sizes, paddle types, and discharge options to match your application.
Efficient Discharge Mechanism: Center or side discharge design for complete material evacuation.
Robust Build Quality: Constructed using high-grade stainless steel or mild steel with wear-resistant liners (if required).
Variable Speed Drives (Optional): Enables precise control of mixing speed for process flexibility.
Dust-Tight Operation: Minimizes environmental contamination and supports safe handling of powders and chemicals.
Applications
Construction adhesives and sealants
Ceramic powders and slurries
Detergents and chemical pastes
Polymer blends and plastic compounds
Animal feed and mineral mixes
Food pastes and dough-like materials
