Product Overview
This automated sieving instrument provides high-precision particle size classification and separation for analytical laboratories and industrial quality inspection facilities. Engineered with a coordinated dual-motion mechanism that combines planar circular oscillation with vertical mechanical tapping, the system eliminates near-mesh blinding and facilitates swift stratification across multi-tier test stacks. It processes dry bulk materials, aggregates, powders, and granular feedstocks reliably with high reproducibility across repeated inspection cycles.
Designed for demanding industrial environments including metallurgy, coal processing, geological exploration, building materials, and chemical processing, the equipment handles batch sizing operations with feed capacities up to 0.2 metric tons per hour. The enclosed structure and automated clamping system accommodate standard test sieves effortlessly, enabling operators to achieve dependable, standard-compliant gradation profiles with minimal manual handling.
Constructed from robust, industrial-grade mechanical components and powered by an oil-free reduction drive, this unit offers exceptional operational longevity and minimal maintenance requirements. Its precision mechanical timing and balanced kinetic architecture ensure uniform energy transfer throughout the entire sieve column, ensuring that analytical testing labs maintain strict consistency and audit-ready data integrity under rigorous continuous-duty testing regimes.
Key Features
- Compound Planar-Tapping Sieving Action: The mechanical drive generates a synchronized planar rotation of 221 oscillations per minute paired with 149 vertical mechanical taps per minute, fluidizing the material bed continuously to overcome inter-particle cohesion and screen blinding.
- Optimized Motion Kinematics: Operating with an exact 12.5 mm gyration radius and a 10 mm vertical tapping stroke, the mechanism imparts balanced multi-axial acceleration that drives difficult, irregularly shaped particles through aperture openings efficiently.
- High-Capacity Sieve Column Architecture: Accommodates up to 8 standard analytical sieves of 200 mm diameter by 50 mm height plus pan and cover, supporting comprehensive particle size distribution analysis in a single automated test run.
- Quick-Action Self-Locking Clamping System: Engineered with a rapid-clamping structural yoke that automatically secures and locks the sieve cover, reducing turnaround time between batch inspections while maintaining uniform axial clamping pressure.
- Eco-Friendly Oil-Free Reduction Mechanism: Utilizes an advanced internal gear reduction transmission with dry-lubricated components, preventing lubricant contamination, reducing mechanical drag, and eliminating routine fluid replacement.
- Programmable Multi-Mode Digital Interface: Features an alphanumeric text display and onboard memory capable of storing three distinct operational parameter recipes, enabling single-touch execution of standardized testing procedures across multiple shifts.
- Enclosed Dust-Containment Housing: Fully sealed exterior cabinet prevents ultrafine airborne particulate emissions during vigorous operation, ensuring a clean laboratory environment and compliance with strict occupational health and environmental guidelines.
- Integrated Auxiliary Dust Extraction Port: Factory-configured with an external connection port for dedicated dust collection or localized vacuum systems, enabling active negative-pressure particulate control during high-dust dry powder classification.
- Energy-Efficient Drive System: Powered by a high-torque three-phase motor drawing less than or equal to 0.4 kW, combining heavy-duty operational stability with minimal electrical power consumption under maximum mechanical load.
Applications
| Application | Description | Key Benefit |
|---|---|---|
| Coal and Coke Gradation | Particle size distribution profiling and quality verification of crushed coal, pulverized fuel, and metallurgical coke samples. | High mechanical agitation prevents cohesive fine coal agglomeration, ensuring precise compliance with fuel processing standards. |
| Mining and Mineral Processing | Stratification of crushed metallic ores, beneficiation concentrates, sands, and crushed quarry aggregates ranging from 6 mm down to 45 µm. | Repeatable kinetic motion delivers consistent separation across coarse fractions and micro-mesh sieves without screen clogging. |
| Metallurgy and Powder Metallurgy | Particle grading and quality control of spherical and irregular metal powders, master alloys, and thermal spray precursors. | Synchronized tapping breaks surface tension and frictional resistance between ultrafine metal grains for true size fraction measurement. |
| Construction Materials and Cement | Automated sieve analysis of cement clinker, ground granulated blast-furnace slag, fly ash, and fine grading sand. | Robust multi-tier clamping supports heavy 200 g test samples per sieve deck while maintaining steady rotational frequency. |
| Chemical and Fertilizer Production | Granulometric classification of synthetic prills, crystalline chemical salts, active detergent powders, and granular fertilizers. | Oil-free internal mechanics eliminate the risk of sample cross-contamination, ensuring absolute purity in analytical testing. |
| Geological and Soil Science Research | Granulometric composition mapping of sediment cores, agricultural soils, silica sands, and mineral exploration specimens. | Programmable preset modes guarantee identical mechanical run cycles across diverse sample batches for publishable research consistency. |
| Refractories and Ceramic Raw Materials | Particle sizing verification of calcined bauxite, tabular alumina, fused silica, and electro-fused ceramic powders. | The combined impact-and-throw motion easily stratifies angular, high-hardness mineral grains without abrasive damage to the sieve fabric. |
