Product Overview
This high-performance laboratory tapping sieve shaker provides standardized particle size analysis and classification for bulk powders, coarse aggregates, and superhard materials. Engineered with a precision dual-action mechanical drive, the system combines horizontal rotary plane motion with synchronized vertical mechanical tapping impacts. This coordinated kinetic action continuously agitates particulate beds, clears sieve mesh apertures, and overcomes electrostatic agglomeration, ensuring complete sample separation in strict accordance with industrial quality control standards.
Designed for demanding testing environments, the machine features a fully enclosed, heavy-duty cabinet architecture that confines airborne particulates and dampens operational noise. It reliably serves testing centers across metallurgical processing, abrasive manufacturing, chemical synthesis, geological exploration, cement production, and pharmaceutical quality assurance laboratories. By maintaining repeatable mechanical forces across every test cycle, the instrument eliminates human variability and provides high-accuracy particle size distribution data.
Constructed with an industrial-grade cast base and an oil-bath transmission system, the equipment ensures exceptional stability and continuous operational reliability under heavy test loads. Its robust clamping mechanism securely accommodates multiple standard analytical test sieves, providing laboratory technicians with reliable, hands-free operation and repeatable analytical throughput cycle after cycle.
Key Features
- Dual-Action Kinetic Sieving Mechanism: Integrates a 290 rpm horizontal planetary shaking motion with a synchronized 156 blows per minute top-hammer tapping action, dislodging near-mesh particles to prevent blinding and accelerate separation.
- Optimized 38 mm Impact Stroke: Delivers calibrated vertical kinetic energy to the top of the test sieve stack, producing uniform dispersion across the entire screen surface without damaging fragile particle morphology.
- Sealed Dust-Tight and Acoustic Housing: Robust cabinet enclosure isolates dust emissions and dampens mechanical vibration, creating a cleaner, safer, and quieter testing environment in busy analytical laboratories.
- Versatile Multi-Diameter Nest Clamping: Heavy-duty vertical clamping assembly flexibly secures standard test sieves with frame diameters of 200 mm, 100 mm, and 75 mm, accommodating diverse testing volumes and protocols.
- Automated Cycle Timing and Shutdown: Integrated precision timer enables pre-set automated test cycles with automatic motor stop, guaranteeing strict consistency across operators and eliminating over-sieving errors.
- Industrial Oil-Bath Transmission Assembly: Precision-machined gears and eccentric shafts operate continuously in a lubricated sealed chamber, minimizing mechanical wear, extending component life, and ensuring smooth, low-friction operation.
- Rigid Cast-Iron Vibration-Absorbing Base: Massive cast-metal foundation provides superior ballast and rigidity, preventing walking, creeping, or structural resonance during high-frequency analytical operations.
- High-Torque 380V Industrial Drive: Driven by a dependable 370 W three-phase electric motor that maintains steady angular velocity and constant impact energy even under full sieve stack loading.
Applications
| Application | Description | Key Benefit |
|---|---|---|
| Abrasives & Superhard Powders | Grading synthetic diamond, silicon carbide, fused alumina, and cubic boron nitride (CBN) grit to verify grit size compliance. | Prevents sieve blinding and achieves sharp grain size distribution separation without particle degradation. |
| Geology & Mineral Exploration | Particle sizing of crushed ores, core samples, raw minerals, and pulverized geological sediments. | High mechanical impact breaks light cohesive agglomerates and ensures rapid clearance of heavy mineral fractions. |
| Metallurgy & Powder Metallurgy | Particle size distribution testing of atomized metal powders, iron alloys, and metallurgical refractory raw materials. | Guarantees batch-to-batch consistency and critical powder flowability compliance for additive manufacturing and pressing. |
| Cement & Construction Materials | Dry sieving analysis of ordinary Portland cement, clinker, fly ash, silica fume, and fine construction aggregates. | Enclosed housing prevents fine dust escape while delivering standardized fineness and grain gradation metrics. |
| Chemical & Polymer Processing | Quality control classification of crystalline chemicals, industrial fertilizers, polymer resins, and pigment granules. | Robust multi-sieve stacking enables simultaneous multi-fraction classification in a single automated operating run. |
| Pharmaceutical & Nutritional Excipients | Granulometric verification of raw active pharmaceutical ingredients (APIs), solid dosage granules, and excipient starches. | Reproducible mechanical energy provides audit-ready sieving consistency aligned with strict pharmacopeial testing criteria. |
| Refractory & Ceramic Formulations | Sieve residue determination and distribution profiling of calcined bauxite, clays, zircon sands, and technical ceramic powders. | Rigid mechanical clamping withstands high-density refractory samples without loosening or losing vertical alignment. |
