Benchtop Activated Carbon Strength Tester Tumbler Ball Abrasion Testing Machine

Product Overview

This benchtop activated carbon strength tester is an analytical instrument engineered to evaluate the mechanical integrity, hardness, and attrition resistance of granular and pelletized activated carbon. Conforming strictly to the standardized tumbler test methodology outlined in GB/T 12496.6-1999 for wood-based activated carbon, this apparatus replicates operational stress through controlled rotational impact and ball collision dynamics. By determining the precise tumbler strength index, the equipment provides essential data regarding how carbon media will endure pneumatic conveyance, bed settling, dynamic fluid friction, and thermal regeneration cycles.

Designed specifically for industrial carbon manufacturing plants, research institutes, water treatment facilities, and environmental testing laboratories, this unit serves as a critical quality assurance tool. The system evaluates whether virgin, spent, or reactivated carbon batches exhibit the mechanical robustness required to prevent premature particle degradation and fine dust generation. While fundamentally engineered to meet standard wood-based carbon criteria, configurable parameters also facilitate comparative mechanical durability evaluations for alternative carbon matrices, including coal-derived and synthetic formulations upon technical alignment.

Constructed with heavy-gauge materials and high-precision mechanical assemblies, the instrument ensures exceptional operational repeatability across continuous laboratory shift work. Its compact benchtop footprint integrates easily into testing workstations without compromising stability or mechanical rigidity. Operators benefit from an automated operational routine that minimizes manual variance, delivering reproducible abrasion resistance data essential for commercial material compliance, process optimization, and industrial batch release.

Key Features

• Standardized Impact Chamber: Fabricated with a rigid inner diameter of 80 ± 2 mm and an internal length of 120 ± 10.5 mm, the precision-machined steel drum provides an exact dimensional envelope for repeatable mechanical tumbling and material collision dynamics.
• Integrated Internal Lifting Ribs: Welded internal lifters continuously elevate carbon samples past a 90-degree rotational angle during drum revolution, allowing the granules and media to fall freely and generate realistic friction, impact, and particle fracturing.
• Calibrated Ball Charge Assembly: The test chamber operates with ten precision-ground carbon-steel balls measuring 14.3 ± 0.2 mm in diameter, exerting controlled kinetic impact forces that standardize mechanical breakdown without pulverizing sound sample cores.
• Regulated Rotational Velocity: Driven by a resilient 0.25 kW gear motor assembly, the drum maintains a constant horizontal rotational velocity of 50 ± 2 r/min, eliminating velocity fluctuations that could distort comparative strength indices.
• Automated Cycle Timing: A high-precision digital countdown timer comes factory-preset to the mandatory 5-minute operational cycle, automatically stopping rotation at test completion to prevent over-milling and operator monitoring errors.
• Resilient Horizontal Drive Architecture: Machined bearing supports and balanced axial mountings ensure smooth rotational stability during dynamic load shifting, minimizing mechanical vibration transfer to laboratory bench tops.
• Ergonomic Quick-Clamping Closure: The steel test cylinder incorporates an intuitive sealing mechanism that provides dust-tight containment during high-energy tumbling while enabling fast sample loading and residue-free material discharge.
• Complete Turnkey Testing Compatibility: Engineered to interface seamlessly with downstream analytical hardware, directly correlating attrition data with standard sieve shaker shaking rates of 221 cycles/min and vibration rates of 147 impacts/min.
