Process Engineering
Material is fed into the gap between three horizontally arranged rollers operating at different surface speeds.
Compression and differential shear progressively break agglomerates and distribute solids through the carrier.
Successive adjustable gaps control the final dispersion before the product is removed from the last roller.
Equipment Benefits
Strong compression and differential shear handle high-viscosity pastes.
Adjustable roller gaps provide direct control of the dispersion process.
Wear-resistant rollers extend service life.
Roll cooling helps protect temperature-sensitive formulations.

Equipment Guidance
The achievable fineness depends on media size, rotor geometry and the number of passes. POLYC confirms the endpoint on your own material in a trial run before the configuration is fixed.
The mill runs with high-purity zirconia or ceramic media selected to the target fineness and the separator opening. Chamber and rotor options are chosen to suit the material; product-contact parts are stainless steel / configurable.
Typical duties cover Printing Inks, Pigment Pastes, Cosmetics. POLYC reviews your material data before recommending a chamber, media size and pass count.
Provide the material type, starting and target particle size, solids loading, batch volume and required throughput. POLYC returns a configuration with media recommendation and an expected pass count.
