Banbury Mixers - Used and Surplus Inventory

Buy used, surplus & second-hand Banbury mixers from IPP – ready to ship

For intensive mixing of tough materials like rubber compounds, plastics, and high-viscosity formulations, Banbury mixers are a trusted solution. With more than 47 years of experience, IPP offers the world’s largest inventory of ready-to-ship process equipment, sourced from 20 complete plant sites and featuring over 15,000 pieces of equipment. Our used Banbury mixers deliver immediate value for manufacturers who need to save capital without sacrificing mixing performance.

Banbury mixers, also known as internal mixers, feature a two-winged or four-winged rotor system within an enclosed mixing chamber. This powerful design creates high shear forces, thoroughly blending and dispersing materials even when they have high viscosities or tough filler content. These mixers excel in compounding rubber for tires, plastics for automotive parts, and specialty composites requiring precise formulation control.

Primary uses across industries

In rubber processing, Banbury mixers compound raw rubber with fillers, oils, and additives for tire, seal, and industrial rubber manufacturing.
In plastics, they blend resins with colorants, stabilizers, and performance-enhancing fillers.
In composite materials, Banbury mixers disperse reinforcement fibers into polymer matrices for high-performance materials.
In chemical manufacturing, they homogenize viscous specialty compounds and adhesives.

Types of materials processed

Rubber compounds for tires and industrial products
Plastics and thermoplastics requiring additive dispersion
Highly filled or reinforced materials
Heat-sensitive compounds requiring careful shear control

Common materials of construction

Banbury mixers are built to withstand extreme mechanical forces, with materials tailored to process needs:

Carbon steel for general rubber and plastic mixing applications
Stainless steel for specialty compounds requiring higher cleanliness standards
Hardened steel or specialty alloys for abrasive fillers and reinforced materials

Key features of Banbury mixers

Enclosed chamber for precise process control
High-shear rotor design for uniform dispersion
