Custom Milling & Consulting, Inc. Three Roll Mill EXAKT 120 S-450

The "S" Series Three Roll Mills are feature rich and provide performance that meets or exceeds that of much larger production models. The unique tensioning system of the "S" Series 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. The rollers are available in 80 mm diameter or 120 mm diameter configurations. In addition, the 120 mm model is also available with rollers either 250 mm or 450 mm long. The roller materials also reflect the care that has gone into the design of the "S" Series. The roller tensioning system and constant gap make it possible to use a variety of materials for the rollers. Chrome plated, hardened steel P9 - Aluminum Oxide (99.7% Al2O3), in two surface finishes P8.8 - Zirconium Oxide (ZrO2) 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.
