Rheology & Processing
Triple Roll Mill
Overview
The Triple Roll Mill is a precision dispersion and grinding system for producing ultra-fine particle dispersions in viscous pastes, inks, coatings, adhesives, pharmaceuticals, cosmetics, and food products. Three precisely gapped, counter-rotating rollers generate intense shear forces that break down agglomerates and achieve particle size reduction to below 5 µm in a single pass.
The adjustable roller gap and speed differential allow process optimization for different viscosities and fineness requirements, making this instrument indispensable for formulation development and small-batch production.
Key Features
- Three-roller design for intensive shear dispersion
- Adjustable gap from 1 µm to 500 µm with micrometer control
- Ceramic (ZrO₂) or hardened steel roller options
- Water-cooled rollers for temperature-sensitive materials
- Integrated apron blade for continuous product collection
- Easy disassembly for thorough cleaning and material change
