4×20L Multi-Position Horizontal Roll Jar Mill – High-Capacity Ultra-Fine Powder Grinding & Mixing for Lab/Batch Production
Overview:
The 4×20L Horizontal Roll Jar Mill is a high-capacity powder milling system designed for ultra-fine grinding and homogenization in laboratory, pilot-scale, and small-batch production. With four independent 20L grinding ports, it enables large-volume processing while maintaining precision and uniformity, making it ideal for R&D, material science, and industrial applications.
Key Advantages:
✔ High-Volume Processing – Four 20L jars allow simultaneous grinding of multiple materials or large batches.
✔ Ultra-Fine & Uniform Powder – Advanced inclined-flow grinding action ensures micron-level fineness with consistent particle distribution.
✔ Precision Control – Digital timing panel with pause & cumulative timing for flexible operation.
✔ Industrial-Grade Durability – Reinforced rubber rollers and optimized rotation speed for long-lasting performance.
✔ Wide Material Compatibility – Processes ceramics, metals, pharmaceuticals, nanomaterials, and more.
Working Principle:
The mill’s rotating jars lift grinding media and materials, which then cascade and collide, achieving efficient pulverization through impact, shear, and friction forces. The multi-position design maximizes throughput without compromising fineness.
Ideal For:
Advanced Material Research (Electronic, Magnetic, Nanocomposites)
Pharmaceutical & Bioengineering Powder Processing
Ceramic Glaze & Metal Alloy Production
Industrial Minerals & New Material Development
Boost productivity with high-capacity, precision grinding for labs and small-scale manufacturing!
