Product Overview
This eco-friendly sealed double-layer small rod mill provides automated, high-precision pulverizing and simultaneous blending for analytical laboratory environments. Engineered to replace manual preparation protocols, this system utilizes high-impact grinding and shear mechanisms within enclosed grinding vessels to process mineral ores, geological specimens, and hard industrial materials directly to analytical fineness. By integrating pulverization and self-homogenization within each sealed vessel, the equipment eliminates secondary screening and manual mixing while containing hazardous airborne particulate.
Designed specifically for commercial assay laboratories, mining metallurgical testing facilities, and academic research institutions, the equipment delivers high throughput within an efficient, small-footprint double-tier architecture. Independent sample chambers allow parallel processing of distinct batches without cross-contamination, making it suitable for high-volume geachemical assays, metallurgy quality control, and advanced ceramic material synthesis.
Engineered for continuous operation under harsh laboratory conditions, this unit features vulcanized drive rollers, heat-treated alloy steel grinding components, and built-in electrical overload protection. The automated grinding cycle pauses during power interruptions and resumes without losing elapsed time data, enabling unmonitored operation while maintaining sample integrity and operational reliability.
Key Features
- Eco-Friendly Sealed Dust Containment: Full-enclosure transparent viewing hood combined with an integrated noise-dampening ventilation system isolates airborne dust and suppresses operational sound, shielding operators from hazardous silica and fine respirable particulates.
- Dual-Action Simultaneous Milling and Homogenization: Grinding barrels utilize moving rod charges to perform progressive size reduction and uniform cross-sectional sample blending simultaneously, removing the need for labor-intensive post-grinding sieving.
- Space-Saving Double-Tier Architecture: Two-level roller layout doubles processing capacity within a compact bench footprint, maximizing sample throughput per square meter of laboratory floor space.
- Precision Vulcanized Rubber Rollers: Heavy-duty 100 mm diameter drive rollers encased in industrial-grade vulcanized rubber deliver slip-free barrel rotation, vibration absorption, and long service life.
- Heat-Treated Alloy Steel Grinding Media: High-strength alloy steel milling cylinders and rods undergo proprietary thermal hardening to resist abrasive wear, prevent barrel wall gouging, and minimize sample contamination during prolonged grinding runs.
- Intelligent Power-Interruption Timing: Digital countdown controller records actual running time exclusively, automatically pausing during power outages and terminating the cycle upon completion to eliminate over-grinding without requiring operator oversight.
- Automatic Overcurrent Safety Protection: Integrated electrical safety circuitry monitors motor current in real time, executing instant shutdown upon encountering mechanical jams or electrical anomalies to protect drive components.
- Modular Multi-Barrel Scalability: Available in standard factory configurations of 4, 8, 12, 16, 24, and 50 barrels, with customizable cylinder dimensions to accommodate custom batch sizes and high-throughput commercial testing schedules.

Why Choose This Product
- Superior Operator Protection and Compliance: The integrated transparent canopy and sound-dampened ventilation ducting establish an enclosed micro-environment, trapping hazardous silica and airborne particulates at the source to satisfy strict occupational health and environmental safety mandates.
- Enhanced Analytical Precision Through Simultaneous Mixing: The balanced rotational rod kinematics ensure that as mineral matrices are comminuted down to 80–200 mesh, the sample continuously self-mixes within the barrel, eliminating density segregation and manual screening errors.
- Robust Heavy-Duty Construction: Built around heavy-wall alloy steel cylinders, precision-ground hardened internal rods, and 100 mm vulcanized rubber rollers, the system delivers quiet operation, minimal structural vibration, and exceptional mechanical longevity under continuous shift use.
- Unattended Automated Processing: With intelligent power-failure memory timing and overcurrent fault shutdown, laboratories can run multi-hour preparation cycles overnight or without active operator supervision, lowering labor overhead while optimizing processing turnaround.
- Flexible Application Engineering: Fully configurable across 4- to 50-barrel layouts with customizable grinding jar volumes, this equipment adapts directly to your facility throughput requirements and specialized material constraints.
