Horizontal Roll Type Alumina Corundum Grinding Jar with Mounting Fixture

This product is a horizontal drum-type ball milling bucket (jar) manufactured from 99% high-purity alumina ceramic. It is specifically designed for applications requiring extreme wear resistance and absolute minimal contamination. Unlike standard jars, this model includes an integrated or complementary external fixture (often a sturdy metal cage or frame) that allows it to be securely mounted and rotated in various mill types, including custom-built or industrial mixing equipment.

• Extreme Abrasion Resistance: Offers unparalleled longevity, even when processing highly abrasive materials with hard media like zirconia or alumina balls.
• Ultra-Low Contamination: The primary advantage. Leaches only negligible traces of alumina, ensuring the chemical purity of sensitive materials like battery chemicals, advanced ceramics, and pharmaceuticals.
• High Compressive Strength: Withstands the significant pressure from large grinding media and dense material loads.
• Excellent Chemical Inertness: Impervious to acids, alkalis, and organic solvents, making it ideal for wet grinding and corrosive environments.
• Non-Magnetic & Electrically Insulative: Essential for processing electronic and magnetic materials without interference.

This jar system consists of two main components:

1. The Ceramic Drum (Bucket):

   Geometry: Horizontal drum-type design. This shape provides a large internal surface area and optimal volume for efficient grinding and mixing dynamics in a rolling or tumbling motion.

   Sealing System: Features a large, securely bolted lid with a high-temperature resistant silicone or Viton® O-ring. This ensures a hermetic seal for:

   • Wet Grinding: Preventing leakage of solvents.
   • Inert Atmosphere Processing: Lids can be customized with gas inlet/outlet valves.
   • Containment: Preventing dust escape during dry grinding.
2. The External Fixture (Mounting Frame):

   Function: This is a critical component. It is a custom-engineered metal frame (typically made from powder-coated carbon steel or stainless steel) designed to:

   • Provide Structural Support: Cradles the ceramic drum, protecting it from impact and shock loads.
   • Enable Secure Mounting: Features trunnions, shafts, or flanges that connect directly to the drive system of a ball mill, roller mill, or other rotating equipment.
   • Facilitate Handling: Allows for safe and easy transportation and installation of the heavy ceramic vessel.

• Unmatched Durability: The wear-resistant corundum ceramic provides a vastly longer lifespan than metal jars in abrasive applications.
• Purity Assurance: Perfect for R&D and production where even trace metal contamination (Fe, Cr, Ni) is unacceptable.
• Versatile Mounting: The included fixture makes it compatible with a wider range of milling and mixing equipment beyond standard jar mills.
• Large Batch Processing: Ideal for scaling up processes from laboratory testing to pilot-scale and small-scale production.

• Battery Material Production: Grinding and mixing of electrode materials (LFP, NMC, Graphite) and solid-state electrolytes.
• Advanced Technical Ceramics: Processing and homogenizing zirconia, silicon nitride, and other high-performance ceramic powders.
• Pigments & Dyes: Achieving ultra-fine, contamination-free dispersion of high-value pigments.
• Pharmaceuticals: Size reduction and mixing of active pharmaceutical ingredients (APIs) under GMP-compliant purity conditions.
• Geology & Mining: Preparation of large samples for elemental analysis (XRF, ICP-MS) without introducing contaminants.

1. The ceramic drum is extremely hard but brittle. Handle with care to avoid impact against hard surfaces.
2. The external metal fixture is mandatory for safe operation and must be securely attached to the mill's drive mechanism.
3. Do not exceed the recommended filling ratio (typically 50-60% of total volume, including grinding media).
4. Avoid thermal shock (sudden large temperature changes).

This horizontal drum-type jar is not a standard off-the-shelf item. It is a heavy-duty, engineered solution for demanding industrial and research applications. The inclusion of a custom fixture makes it incredibly versatile and robust.
