Product Overview
This micro horizontal jar mill is a compact, high-efficiency laboratory grinding and mixing instrument specifically engineered for ultra-fine material reduction. Operating on advanced high-speed friction and shear principles, the equipment drives a horizontally oriented jar across dual precision rubber rollers at rotational speeds up to 1800 rpm. It effectively processes brittle, low-to-medium hardness feed materials below 0.5 mm, achieving consistent output fineness down to the sub-micron scale (< 1 µm). By maintaining a horizontal center of gravity during rotation, the unit guarantees uniform media motion and optimal contact distribution throughout the grinding chamber, serving as an essential solution for high-throughput analytical sample preparation and material research.
Designed to meet the stringent demands of modern research laboratories, pharmaceutical R&D facilities, and advanced material development centers, this benchtop system handles sample volumes ranging from 50 ml to 180 ml. The equipment provides exceptional versatility by supporting both dry and wet grinding modes, as well as homogeneous powder blending. Whether preparing high-purity ceramic precursors, dispersing fine pigments, or homogenizing delicate pharmaceutical compounds, the instrument provides an uncompromised balance of power, cleanliness, and process control in a remarkably small operational footprint.
Constructed with an IP65-rated protective enclosure and engineered around industrial-grade drive components, this system delivers outstanding operational stability and long-term reliability under intensive daily usage. The integrated digital control architecture provides precise regulation of processing parameters, while safety features such as a transparent PC viewing window and integrated internal lighting enable continuous visual monitoring. Users can rely on this equipment for consistent, contamination-free processing that preserves sample integrity across thousands of operating cycles.
Key Features
- High-Speed Friction Processing: Operates at continuously adjustable speeds up to 1800 rpm across dual high-friction rubber rollers, transferring optimal kinetic energy to the grinding media to achieve sub-micron output particle sizes (< 1 µm) within 3 to 30 minutes.
- Multifunctional LCD Control Unit: Features a intuitive digital interface supporting continuous grinding, intermittent milling, alternating direction cycles, precision countdown timing, speed adjustment, and integrated power-off memory for automatic cycle resumption.
- Flexible Jar and Media Metallurgy: Accommodates high-purity Zirconia (ZrO2) and Tungsten Carbide (WC) grinding jars and media (spherical or cylindrical options, 42 grinding rods included) to completely eliminate cross-contamination and match specific material hardness requirements.
- Rapid Jar Clamping System: Equipped with a quick-action securing fixture that firmly locks the grinding container onto the drive rollers, enabling tool-less jar changes, reducing operator fatigue, and minimizing turnaround time between experimental batches.
- Robust IP65 Enclosure Engineering: Fully sealed housing with an IP65 protection rating prevents dust ingress and fluid splash damage, protecting internal electronic circuits and mechanical drives in harsh lab environments.
- Integrated Process Illumination & PC Viewing Window: Features internal high-efficiency LED lighting coupled with a high-impact polycarbonate inspection window, allowing real-time monitoring of slurry dynamics and powder flow without opening the processing chamber.
- Ultra-Compact Footprint: Compact physical dimensions of 260 x 250 x 140 mm and a net weight of 10 kg maximize available benchtop space while providing low power consumption of just 60W across universal voltage standards.
