Product Overview
This vertical testing instrument provides laboratory-grade evaluation of the mechanical strength, hardness, and attrition resistance of wood-based granular activated carbon. Operating in strict accordance with the standardized test methodology defined in GB/T 12496.6-1999, the equipment simulates dynamic mechanical degradation through controlled rotation, steel ball impaction, and cascading abrasion. By delivering uniform mechanical agitation within precisely dimensioned steel test cylinders, the system quantifies the structural integrity and friability threshold of porous carbon matrices under industrial handling and continuous fluid-flow conditions.
Engineered specifically for activated carbon manufacturers, environmental engineering testing stations, municipal water treatment facilities, and solvent recovery plants, this testing unit delivers rapid and reproducible ball-pan abrasion metrics. The equipment subjects granular samples to standardized axial rotation where internal radial lifter ribs continuously elevate and drop carbon particles and grinding media across a calibrated path. Measuring mass retention across analytical sieves post-attrition yields critical quality metrics that directly reflect in-service carbon lifespans and dust-generation propensities in deep-bed adsorption towers.
Designed for demanding industrial quality assurance and continuous academic research, the apparatus integrates an industrial-duty drive mechanism, precision-machined friction cylinders, and an automated timed sequence. Robust metallurgical construction ensures strict dimensional tolerances and rotational velocity stability over thousands of test cycles. Whether implemented for routine lot verification, feed raw material evaluation, or production batch certification, the apparatus guarantees exceptional inter-laboratory repeatability and reliable baseline performance data.
Detail & Parts
Key Features
- Standardized Methodology Compliance: Fully engineered around the strict geometry and procedural criteria of GB/T 12496.6-1999, ensuring that measured drum abrasion indices and retention rates withstand standard regulatory and commercial scrutiny.
- Precision Horizontal Axial Rotation: Driven by a balanced motor-gear transmission, the testing assembly maintains a constant rotational velocity of 50 ± 2 r/min to eliminate inertial variations and preserve uniform kinetic collision energies across sequential runs.
- Dual Standardized Test Cylinders: Includes both No. 1 and No. 2 heavy-duty steel cylinders fabricated with identical internal dimensions (80 mm ID × 120 mm length, 3 mm wall thickness) and controlled Ra 6.3 internal surface finishes, enabling flexible compliance with diverse granular test matrices.
- Symmetric Internal Agitation Ribs: Cylinder No. 2 features two precision-welded, 180-degree opposed longitudinal lifter ribs (10 mm height × 4 mm width) that uniformly lift granular carbon beyond the 90-degree threshold to induce standardized free-fall attrition.
- Hardened Steel Impact Media: Supplied with a dedicated suite of 10 precision-ground carbon steel balls manufactured to an exacting 14.3 ± 0.2 mm diameter, guaranteeing consistent kinetic impact energy and negligible media wear during intensive testing.
- Automated Preset Digital Timing: An integrated industrial timer allows pre-setting of standard 5-minute testing sequences with automatic motor shutoff, minimizing operator intervention and eradicating elapsed-time measurement errors.
- High-Torque Industrial Drive System: Powered by a 0.55 kW three-phase industrial motor operating at 380 V, delivering seamless starting torque, quiet continuous operation, and sustained speed stability under full sample and media load.
- Rigid Structural Base Frame: Fabricated with high-grade structural steel and a vibration-damping chassis to ensure vertical stability, reduced operational noise, and long-term mechanical alignment in busy laboratory environments.
