Product Overview
This horizontal reciprocating mechanical sieve is engineered for precision particle size distribution analysis of coarse, high-density bulk materials such as iron ore, sinter, pellets, and coal. Designed in compliance with international metallurgical testing standards, the equipment provides automated, repeatable agitation to ensure precise separation across standardized square-mesh screens. By replacing labor-intensive and erratic manual shaking with continuous mechanical reciprocating action, this system establishes rigorous quality verification benchmarks for industrial laboratories, processing plants, and port inspection terminals.
Built to withstand continuous duty cycles in demanding testing environments, the unit houses a reinforced eccentric drive mechanism powered by an energy-efficient industrial electric motor. The enclosed drive configuration translates rotary motion into a uniform linear reciprocating stroke, driving standard 800 mm by 500 mm screen frames with exceptional stability. Standardized clamping hardware and integrated vibration dampening allow operators to configure single screens or stacked multi-tier sieve arrays without structural deflection, providing comprehensive fractional analysis in a single automated operational sequence.
With an emphasis on analytical repeatability and operational safety, this equipment integrates an intuitive electrical control console featuring digital countdown timing and automated cycle termination. This precise duration management eliminates operator error, protects delicate specimen integrity against excessive attrition, and ensures adherence to ISO cold-strength and particle sizing methodologies. From raw ore receiving docks to blast furnace feed blending facilities, this system delivers dependable, verifiable sizing data essential for optimizing burden permeability and metallurgical productivity.
Key Features
- Heavy-Duty Eccentric Drive Mechanism: The balanced eccentric drive assembly translates motor torque into a stable, high-torque linear reciprocating stroke via precision guide bars, ensuring uniform specimen migration across the entire mesh surface without lateral dead spots or erratic material bouncing.
- Adjustable Reciprocating Stroke: The mechanical stroke distance can be calibrated across an adjustable range from 160 mm to 280 mm with fixed setting options (including 40 mm, 160 mm, 200 mm, 240 mm, and 280 mm amplitudes), allowing technicians to optimize kinetic energy transfer according to specimen bulk density and grain morphology.
- High-Throughput Multi-Tier Stacking: Accommodating up to five 800 mm by 500 mm standardized rectangular screen trays simultaneously, the robust support frame allows single-pass multi-fraction classification for batch charges up to 50 kg per test run.
- Integrated Digital Time Controller: A solid-state time relay controller with a high-visibility digital display allows precise cycle settings up to a standard 12-minute testing sequence, terminating operation automatically to eliminate operator variance and ensure rigorous ASTM and ISO test standard compliance.
- Ergonomic Quick-Clamp Locking System: Heavy-duty slide rods equipped with industrial wing nuts and secure retaining plates provide rapid screen installation, firm clamping pressure, and tool-free changeovers between consecutive batch runs.
- Industrial Enclosed Electric Motor: Driven by a robust 1.5 kW high-torque motor linked through a durable industrial belt and pulley system, the equipment maintains a steady frequency of 240 cycles per minute under heavy material loads without thermal overload.
- Standardized Screen Mesh Selection: The system supports interchangeable wire-cloth and perforated-plate screens with standard aperture sizes including 40×40 mm, 25×25 mm, 16×16 mm, 10×10 mm, 6.3×6.3 mm, and 5×5 mm to cover metallurgical sizing classifications.
- Durable Heavy-Gauge Construction: Fabricated from structural carbon steel with industrial-grade protective coatings, the machine frame resists mechanical fatigue, vibration stresses, and corrosive plant atmospheres encountered in mining and smelting facilities.
