Milling Jar
Roalox Alumina-Fortified Grinding Jars
These ceramic jar bodies have been formulated to provide about 4 times the wear rate of our competitor’s porcelain jars. Lower silica content cuts silica contamination by more than half. High-strength, impact-resistant composition minimizes chipping and breakage.
Features
- Positive lid locking bar and hand well for quick, easy opening and closing
- Precision ground cover and gasket seat assure leak-proof fit
- Wide mouths for fast emptying, cleaning, loading
- Gaskets are oil, solvent and chemical-resistant Neoprene rubber
- Inside surfaces are unglazed
High Alumina Grinding Jars
Features
- Same design features as Roalox Mill Jars
- Ultra-high fired ceramic body composed primarily of high-grade aluminum oxide
- Extremely high abrasion resistance, long service life, negligible contamination factor
- Recommended where silica contamination must be held to an absolute minimum
- Polyurethane-coated body minimizes breakage
Unlined Stainless Steel Jars
Features
Available in 7 standard sizes in Type 304 Stainless Steel, with or without internal lifter bars. Easy to use, fast cleaning. Features wide mouths, curved inside corners.
Lined Steel Grinding Jars
Features
- All sizes have quick-change snap-in liners This feature is especially significant when varied materials are milled and cross contamination must be avoided
- Using a separate liner for each material protects the product, saves clean-up time, reduces number of jars required
- Jars are carbon steel
- Recommended where silica contamination must be held to an absolute minimum
- Buna-N, EPDM, Low-Ash rubber, Neoprene, and Polyurethane liners are available
Note: Cover liners are not snap-in; a different cover is needed for use with each liner
