Product Overview
This high-performance mechanical shaking sieve is specifically engineered for post-drum mechanical strength determination of metallurgical coke and foundry coke. By automating the secondary classification process after drum abrasion and shatter testing, the equipment eliminates operator-dependent manual sieving, prevents manual aggregate poking, and dramatically reduces ergonomic physical strain in industrial testing facilities.
Designed for rigorous industrial metallurgy laboratories, coking plants, and third-party inspection bureaus, this unit standardizes sample sizing to guarantee exceptional measurement accuracy and inter-laboratory comparability. Its robust angular steel construction, coupled with an integrated reduction gear and crank mechanism, delivers smooth, synchronized oscillation across dual screening decks, ensuring repeatable grain size distribution.
Engineered to withstand abrasive coke charges and continuous duty cycles, this system integrates automated relay-controlled cycle timing with high-torque motor drive mechanics. The result is an exceptionally durable, high-throughput preparation platform that boosts daily sample turnaround while maintaining strict conformity to global coke strength indices.
Detail & Parts
Key Features
- Automated Cycle Timing Control: Integrated high-accuracy time relay manages the entire 45-second screening run automatically, ensuring reproducible agitation duration across shifts while allowing operators to attend to other analytical tasks.
- Precision Swing Agitation Dynamics: Calibrated crank-linkage assembly generates a uniform 40° to 45° oscillation stroke, fluidizing dense metallurgical coke samples across the entire deck area without blinding screen apertures.
- Dual-Tier Interchangeable Sieve Plates: Configured standard with a choice of 40 mm or 25 mm upper aperture plates and a 10 mm lower plate, accommodating diverse ISO, ASTM, and national testing protocols with rapid screen changeover capabilities.
- High-Efficiency Gearbox Transmission: Heavy-duty 1.5 kW electric motor couples directly to an industrial speed reducer via flexible wheel couplings, ensuring steady low-frequency, high-torque oscillatory drive performance under full operational payload.
- Ergonomic Quick-Discharge System: Purpose-built release mechanism allows processed coke fractions to slide directly into dedicated collection hoppers, preventing particle degradation and eliminating manual scooping.
- Rigid Structural Steel Framework: Fully welded structural angle-iron chassis absorbs dynamic kinetic forces and vibration harmonic resonance, providing rock-solid bench stability and extending component operational service life.
- Wear-Resistant Perforated Screening Media: Precision-milled steel deck apertures maintain accurate boundary dimensional tolerances against highly abrasive foundry coke, preserving long-term analytical validity.
Applications
| Application | Description | Key Benefit |
|---|---|---|
| Metallurgical Blast Furnace Coke Quality Control | Automated classification of blast furnace coke fractions following Micum (M40/M10) or Irsid (I20/I10) drum index tests. | Delivers consistent, operator-independent index verification to optimize blast furnace fuel permeability and operational efficiency. |
| Foundry Coke Shatter and Abrasion Testing | Sizing structural integrity and fracture resistance of large-block foundry coke after mechanical tumble testing. | Replaces laborious hand-sieving of heavy lump coke while safeguarding testing integrity through standardized 45-second screening cycles. |
| Commercial Coke Oven Plant Production Monitoring | Routine batch screening in coking plant process control laboratories to monitor carbonization quality and post-quenching mechanical resilience. | Rapid multi-tier separation minimizes assay turnaround times, enabling rapid optimization of coal blending formulations and coking times. |
| Third-Party Metallurgical Inspection Services | High-throughput contractual conformity verification for commercial cargo transshipment, shipping terminals, and independent test facilities. | Guarantees stringent inter-laboratory repeatability and complies with international metallurgical test standards across global testing networks. |
| Coal and Carbon Materials Research Laboratories | Granulometric and structural degradation research evaluating pilot-scale coke batches, bio-coke briquettes, and novel carbon anodes. | Facilitates flexible interchangeability of upper screen plates (25 mm or 40 mm) for variable experimental research criteria. |
| Ferroalloy and Non-Ferrous Smelting Quality Assurance | Mechanical grading of specialty reduction carbon and nut coke subjected to physical stress simulation drums. | Enhances sample throughput while eliminating dust exposure and manual labor through automated mechanical batch separation. |
