EXAKT Superfine Series

Efficient bench top three roll mill units for demanding requirements

Highlights


The EXAKT Three Roll Mill Superfine Series are feature rich models providing performance that meets or exceeds that of much larger production models.

The unique tensioning system minimizes the free play in the roller ball bearings insuring a more constant gap and ultimately a finer, more uniform particle size in the product. And the gap is easily set with a single hand wheel for parallel roller adjustment to 3-5 microns at its closest setting.

With the introduction of ceramic-based rollers, metal contamination of the product during processing has been dramatically reduced. With the ensuing introduction of ceramic scraper blades, metal contamination can be eliminated. Scraper blades are available in plastic, surface treated steel, aluminum oxide and zirconium oxide.

Optional Equipment


  • Frequency Inverter for Speed Control – Superfine models are available with dual speed motors. For optimum performance, the variable speed control of the frequency inverter provides better control and the best results. By maintaining a constant speed ratio between the rollers and thus constant friction, the Superfine models are ideal for processing viscous or thermally sensitive products.
  • Heating & Cooling System for the Rollers – All Superfine models can be equipped with an internal circulation system for heating or cooling the rollers. This must be installed at the factory. EXAKT also provides a heating/cooling device if a chilled or hot water source is not available.
  • Solvent Dispensers – With increased viscosity of product and increased friction, additional heat can be generated along the plastic guides that direct the flow of product. The product dispensers deliver additional liquid or solvent to the area most likely to become dry, resulting in a smoother flow of product and ease in cleaning.
