Double Arm Mixers - Used and Surplus Inventory | IPP

IPP has your used, surplus and secondhand double arm mixers – in stock for rubber, adhesives, sealants, and heavy-duty pastes

Tackle dense formulations with IPP’s ready-to-ship double arm mixers built for intensive shear and mixing control

Used double arm mixers are designed for blending high-viscosity materials that standard agitators can’t handle. Featuring two counter-rotating blades (typically sigma or Z-shaped), these mixers apply intense kneading and folding action—ideal for adhesives, rubbers, mastics, and heavy polymer compounds. With more than 47 years of process expertise, IPP supplies used, surplus and secondhand double arm mixers from 20 global plant sites and offers a deep inventory of 15,000+ process systems ready for rapid deployment.

IPP carries jacketed and non-jacketed double arm mixers from top manufacturers like Baker Perkins, Day, Kneader Machinery Co., Jaygo, and Littleford.

Applications and industries

• In rubber and elastomer production, for compounding raw rubber with fillers and oils
• In adhesives and sealants, for kneading viscous polymers and curing agents
• In plastics and resins, for blending PVC, polyurethanes and thermoplastics
• In ceramics and refractories, for wet mixing clays, powders, and pastes

Types of materials processed

• Very high-viscosity compounds (1 million+ cps)
• Semi-solids, mastics and dough-like mixtures
• Reactive materials requiring uniform blending under controlled temperature
• Solvent-based formulations in explosion-proof environments

Common materials of construction

These mixers must withstand torque, abrasion, and chemical exposure:

• Hardened carbon steel for rugged compounding applications
• 316L stainless steel for food, pharma or corrosive blends
• Chrome-plated or coated internals for easy cleanout and non-stick performance
• Jacketed chambers for heating or cooling during mixing

Key features of double arm mixers

• Sigma or Z-type counter-rotating blades for aggressive kneading
• Heavy-duty gear or hydraulic drives for torque transmission
• Split troughs for easier discharge and cleaning
• Vacuum, pressure, or explosion-proof options available
• PLC-controlled operation for precise timing and repeatability
