This product is a horizontal alumina ball mill tank specifically designed for laboratory roller mills that utilize a screw-press mechanism for securing and sealing the jar. Manufactured from high-purity 99% alumina ceramic, these jars are built for super wear-resistance and minimal contamination during grinding and mixing processes. They are available in standard capacities of 2-liter, 3-liter, and 5-liter to fit corresponding mill models.
2. Core Design & Sealing Mechanism
The key feature of this jar is its screw-press compatibility:
Screw-Press Locking System:
The jar is designed to be placed horizontally between two rotating rollers. A central threaded screw (or multiple screws on the pressure plate) is manually turned to press a metal pressure plate firmly against the end of the jar.
Function:
Secures the Jar: Holds it firmly in place against the rotating rollers, ensuring it turns without slipping.
Creates the Seal: Compresses the lid tightly against the jar body (via an internal O-ring) to create a hermetic seal, preventing leakage of solvents or dust.
Components:
The system typically consists of:
The Alumina Ceramic Jar: The main grinding container.
The Lid: Usually made from alumina or stainless steel, featuring a central port.
The Sealing Gasket: A silicone or rubber O-ring placed in a groove on the lid or jar mouth.
The Pressure Cap/Plate: A metal end-cap that transfers the force from the central screw to the jar lid.
3. Key Features & Benefits
Secure Sealing: The screw mechanism provides strong, even pressure for a reliable seal, suitable for wet grinding with solvents.
Excellent Wear Resistance: The 99% alumina construction ensures extreme longevity and resistance to abrasion from grinding media.
Contamination-Free: Alumina ceramic ensures no metallic impurities (Fe, Cr, Ni) contaminate your sample, crucial for battery materials, ceramics, and analytical chemistry.
Chemical Inertness: Highly resistant to acids, alkalis, and organic solvents.
Designed for Stability: The horizontal cylindrical shape is optimized for the tumbling and cascading motion in roller mills, ensuring efficient and homogeneous mixing/grinding.

5. Applications
These jars are ideal for:
Battery Material Research: Mixing electrode slurries (e.g., LFP, NMC, Graphite).
Ceramic Industry: Grinding and homogenizing ceramic glazes and raw materials.
Paint & Ink Production: Laboratory-scale dispersion of pigments.
Geology & Chemistry: Sample preparation and mixing where purity is critical.
Pharmaceuticals: Blending and size reduction of active ingredients.
6. Usage Instructions
Loading: Fill the jar with grinding media and material, not exceeding 50-60% of its total volume.
Sealing: Place the lid on the jar with the O-ring in place. Position the metal pressure cap on the end.
Mounting: Place the assembled jar horizontally into the mill between the two rollers.
Pressing: Turn the central screw handle clockwise to apply pressure until the jar is firmly secured and will rotate with the rollers without slipping.
Process: Start the mill and run for the required duration.
Unloading: After stopping, loosen the screw to release pressure before removing the jar.
Note: Always ensure the jar and locking mechanism are clean and undamaged before use. Avoid over-tightening the screw, as excessive pressure could potentially damage the ceramic.
This screw-press sealed horizontal alumina jar is a robust and effective solution for reliable, contamination-free mixing and grinding in compatible laboratory roller mills.
