Product Overview
This variable frequency rotary sample divider is an advanced automated system engineered for high-precision, representative splitting of bulk granular materials. Fully compliant with GB474 standard protocols for sample preparation, this system converts raw bulk lots into multiple identical sub-samples with minimal statistical variance. Powered by a heavy-duty gear motor paired with a variable frequency drive (VFD), the equipment maintains uniform turntable rotational speeds under varying loads, eliminating human bias and manual error from sample preparation workflows.
Designed for demanding industrial environments, the machine is widely deployed across coal testing, mining extraction, metallurgical quality control, power generation facilities, building material processing, and research laboratories. It provides reliable bulk sample reduction for raw minerals, sinter, coke, clinker, and fine chemicals, ensuring downstream analytical results accurately reflect total batch characteristics.
Constructed entirely from premium SUS304 stainless steel, the equipment provides exceptional corrosion resistance and mechanical durability. Featuring an enclosed dust-tight housing and an integrated dust extraction interface, this rotary sample splitter protects operating environments from hazardous airborne particulates while maintaining sample integrity during continuous division operations.
Key Features
- Precision Variable Frequency Control: Advanced VFD controller allows stepless speed adjustment from 4 to 60 r/min, enabling operators to optimize rotational parameters according to specific particle dynamics and splitting requirements.
- Controlled Electromagnetic Vibratory Feed: Integrated standard vibrator provides constant, uniform material delivery into the dividing funnel, preventing mass surges and ensuring repeatable division ratios across all sample buckets.
- Full SUS304 Stainless Steel Construction: All material-contacting surfaces, internal hovers, funnels, and sample buckets are manufactured from high-grade SUS304 stainless steel to eliminate sample contamination and withstand abrasive material wear.
- Dust-Sealed Protection with Extraction Port: Fully enclosed cabinet structure features a built-in dust collection port that connects directly to laboratory exhaust systems, keeping working spaces clean and containing hazardous dust.
- Modular 6 or 8 Bucket Configurations: Includes precision-fitted sample receiving buckets equipped with ergonomic quick-release handles for rapid collection, seamless dismounting, and simplified cleaning routines.
- Flexible Division Ratios: Configurable dividing setup delivers division ratios ranging from 1/2 down to 1/8, enabling flexible reduction of large bulk samples into smaller, highly representative analytical portions.
- Indexable Manual Turntable Drive: Main turntable assembly can be indexed manually, bringing heavy shovel buckets directly to the front access door to streamline bucket retrieval and minimize operator fatigue.
- Robust Industrial Gear Drive Motor: Powered by high-torque gear motors engineered for continuous duty, delivering smooth rotational energy without slippage or speed drift during high-throughput operation.
Applications
| Application | Description | Key Benefit |
|---|---|---|
| Coal & Energy Testing | Preparation of run-of-mine coal, crushed coal, and coking coal for calorific, ash, and volatile matter analysis per GB474 standards. | Ensures complete statistical representation of bulk coal lots, reducing laboratory analytical error. |
| Mining & Ore Extraction | Splitting raw iron ore, sinter, pellet ore, and non-ferrous mineral fractions prior to XRF or wet chemical assaying. | Heavy-duty SUS304 construction withstands highly abrasive mineral fines without sample contamination. |
| Metallurgy & Coke Quality | Uniform sub-sampling of metallurgical coke, slag, flux materials, and ferroalloys in steel plant quality control units. | Handles high throughputs up to 1800 kg/h while maintaining identical particle size distribution across all buckets. |
| Building Materials & Aggregates | Sub-dividing limestone, cement clinker, gypsum, and raw rock aggregate samples for physical and chemical compliance testing. | Dust-enclosed operation prevents fines loss, preserving true particle size distribution in fine aggregate samples. |
| Chemical & Fertilizer Processing | Precision division of granular fertilizers, polymer pellets, catalyst carriers, and industrial mineral salts. | Smooth, non-contaminating stainless steel path ensures zero cross-batch chemical contamination. |
| Scientific Research & Third-Party Labs | Bulk sample splitting for contract research, geological surveys, and standardized reference material production. | Stepless VFD speed regulation allows precise matching of division mechanics to novel or non-standard sample types. |
