With over 47 years of experience and more than 15,000 pieces of equipment across 20 global plant sites, IPP offers deep inventory and fast access to used intensive mixers. These mixers provide controlled, high-energy mixing for tough materials—where standard paddle or ribbon systems fall short.

What does an intensive mixer do?

An intensive mixer uses powerful rotors and fixed walls to apply high shear forces to dense or highly viscous materials. This mechanical action ensures uniform dispersion of fillers, resins, binders, and other components—often under elevated pressure or temperature conditions.

Commonly used for:

• Rubber and elastomer compounding
• High-viscosity plastic blends
• Carbon black and silica dispersion
• Reactive adhesives and sealants
• Specialty chemical processing

What materials do they process?

Used intensive mixers can handle a wide range of dense and difficult-to-blend materials, including:

• Synthetic and natural rubber
• Plastic pellets and resin bases
• High-viscosity polymers
• Powders with liquid binders
• Thermal-set adhesives and compounds

Many systems can operate under vacuum, with jacketed bowls for heating or cooling.

Common materials of construction

IPP stocks intensive mixers in robust configurations designed for durability and strength. Most models feature:

• Carbon steel or stainless steel bodies
• Hardened alloy rotors
• Heavy-duty bearings and seals
• Optional PLC control packages

Some units are rated for high torque and come with dual-drive motors for greater control.

Frequently asked questions – intensive mixers

What’s the difference between an intensive mixer and a Banbury mixer?

Banbury mixers are a type of intensive mixer but tend to be larger, with tilt discharge and heavier-duty specs for rubber and tire compounding.

Are intensive mixers suitable for solvent-based formulations?

Yes. Many systems can handle flammable or reactive materials when properly vented and monitored.

Can these mixers be automated?

Many used units include automation controls or can be retrofitted for integration into modern process lines.
