Product Overview
This post drum mechanical sieve shaker is an industrial grading apparatus engineered specifically for testing the mechanical strength and degradation resistance of sinter and pellet ore. Designed to integrate directly downstream of standard tumble drums, the equipment automates the classification of tumble-tested metallurgical charges. By replacing labor-intensive manual sieving methods, this system eliminates operator variability, significantly reduces physical exertion, and delivers repeatable particle size separation compliant with rigorous metallurgical testing standards.
Built for the harsh testing environments of metallurgy laboratories, quality inspection stations, and production plant assay centers, the equipment provides stable mechanical oscillation under heavy bulk loads. The machine accepts coarse, abrasive ore samples straight from the tumbling drum, classifying them across precision aperture screens to determine post-impact shatter and abrasion indices. Its enclosed configuration and rapid cycle capabilities streamline sample workflows in high-throughput blast furnace burden evaluation facilities.
Engineered with an emphasis on mechanical resilience and operational longevity, this unit combines welded structural steel framing with high-torque gear reduction and an enclosed dust control shroud. Procurement managers and metallurgical laboratory directors can rely on this rugged sieving platform to maintain rigorous process quality benchmarks, minimize laboratory fugitive dust emissions, and optimize routine burden testing cycles with zero downtime.
Detail & Parts
Key Features
- Heavy Duty Welded Structural Frame: Engineered from rigid structural angle iron and heavy-gauge plate, the welded chassis absorbs mechanical vibration and stabilizes the drive assembly during continuous screening operations.
- Precision Fixed-Angle Oscillating Motion: The drive linkage generates a sustained 45-degree swinging angle powered by an eccentric crank mechanism, ensuring continuous ore agitation across the entire screen deck surface without particle blinding.
- Automated Cycle Timer Control: An integrated industrial time relay governs the screening duration with automated cycle shutdown at 1.5 minutes, eliminating human timing error and ensuring identical test conditions across sequential metallurgical batches.
- High-Torque Industrial Gear Motor: Equipped with a reliable 1.1 kW electric motor coupled to an inline speed reducer via flexible wheel coupling, the unit produces consistent torque output under heavy aggregate loads.
- High-Capacity Wear-Resistant Screen Deck: The large 800 mm by 500 mm screening bed accommodates full post-drum sample volumes, utilizing interchangeable perforated plates with standardized 6.3 mm by 6.3 mm or 5.0 mm by 5.0 mm square apertures.
- Sealed Environmental Dust Cover: A fully fitted protective enclosure seals the entire screening zone during operation, containing toxic mineral dust, preventing ambient particulate emissions, and maintaining workplace air quality standards.
- Rapid Discharge Gravity Chute: The machine includes an integrated bottom discharge mechanism that channels classified ore fractions directly into collection hoppers upon test completion, minimizing sample handling turnaround times.
- Repeatable Mechanical Classification: Standardized mechanical displacement replaces subjective manual hand-shaking, establishing rigorous repeatability in calculating tumble strength index (ISO/ASTM standardized degradation metrics).
