Product Specification: 99% Alumina Ceramic Horizontal Drum-Type Ball Milling Jar
Product Name: Horizontal Drum-Type Alumina Corundum Grinding Jar with Mounting Fixture
Model Series: [Your Company Prefix]-HD-Al2L / HD-Al5L / HD-Al10L (Example for 2L/5L/10L)
Category: Heavy-Duty Grinding Jars for Ball Mills & Mixing Equipment
1. Product Overview
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.
2. Core Material & Properties
Material: 99% Alumina Ceramic (Corundum)
Alumina Content (Al₂O₃): ≥ 99%
Density: ≥ 3.8 g/cm³
Hardness: Mohs Hardness ≥ 9 (HRA ≥ 88)
Key Properties:
- 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.
3. Design & Structure
This jar system consists of two main components:
-
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.
-
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.

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