MingShen Science YTSZH-4 Automatic Standard Sieve Shaker

Overview

The MingShen Science YTSZH-4 Automatic Standard Sieve Shaker is a mechanically driven, precision-engineered particle size analyzer designed for standardized dry-sieving operations in quality control laboratories, geological sample preparation, construction materials testing, and mineral processing facilities. It operates on the principle of combined orbital oscillation and vertical tapping—mimicking the ASTM E11 and ISO 3310-1 prescribed motion profiles for mechanical sieve shakers. This dual-motion mechanism ensures efficient particle stratification and separation across multi-layered sieve stacks, minimizing blinding and maximizing throughput reproducibility. The device conforms to national standard GB/T 6003.1–2012 (equivalent to ISO 3310-1) for test sieve specifications and is calibrated for use with standard 200 mm diameter sieves. Its robust cast-iron base and balanced drive system deliver stable, low-vibration operation during extended runs—critical for GLP-compliant routine analysis.

Key Features

• Integrated dual-motion actuation: 221 oscillations per minute (orbital radius 12.5 mm) + 147 vertical taps per minute (6 mm stroke amplitude), ensuring uniform energy transfer across all 10 sieve levels.
• Precise digital timer (0–60 min) with auto-stop function, supporting repeatable test durations required by ASTM C136, ISO 2591-1, and GB/T 1345 cement fineness protocols.
• Modular 10-tier sieve stack support (max. 400 mm total height), compatible with standard 200 mm diameter test sieves including woven wire, perforated plate, and electroformed mesh types.
• Three-phase 380 V / 50 Hz motor (370 W, 2800 rpm) with thermal overload protection and sealed bearing assembly for continuous-duty reliability.
• Stainless steel clamping ring and quick-release locking mechanism enable tool-free sieve assembly/disassembly and minimize cross-contamination risk.
• Compact footprint (520 × 370 × 870 mm) and 100 kg reinforced chassis ensure stability on standard lab benches or dedicated vibration-isolated platforms.

Sample Compatibility & Compliance

The YTSZH-4 accommodates dry, free-flowing granular materials—including aggregates, crushed ores, powdered pharmaceutical excipients, ceramic raw materials, and fly ash—with particle sizes ranging from 80 mesh (177 µm) up to 100 mm. It is not suitable for cohesive, hygroscopic, or fibrous samples without pretreatment (e.g., drying or anti-static agents). All operational parameters align with ISO/IEC 17025 requirements for equipment verification: amplitude, frequency, and timing accuracy are traceable to national metrology standards. The unit supports audit-ready documentation when used within GMP-compliant environments, particularly where sieve analysis forms part of raw material release testing (e.g., USP for particle size distribution in solid dosage forms).

Software & Data Management

As a standalone electromechanical instrument, the YTSZH-4 does not include embedded software or data logging capabilities. However, its deterministic timer and repeatable motion profile make it fully compatible with external LIMS integration via manual entry or barcode-scanned test records. Users may document sieve weights pre- and post-analysis using certified analytical balances (e.g., METTLER TOLEDO XSR series) and export mass retention data into Excel-based reporting templates compliant with FDA 21 CFR Part 11 when paired with electronic signature workflows. Optional accessories—including calibrated reference standards and NIST-traceable sieve certification reports—are available through authorized MingShen Science distributors.

Applications

• Aggregate gradation analysis per ASTM C136/C136M for concrete and asphalt mix design.
• Mineral liberation assessment in metallurgical beneficiation studies.
• Cement fineness verification under GB/T 1345 and ISO 9308.
• Quality assurance of industrial sands, foundry molding materials, and catalyst supports.
• Educational demonstration of particle size distribution theory in materials science curricula.
• Preparation of representative subsamples prior to laser diffraction or sedimentation analysis.

FAQ

What sieve diameters is the YTSZH-4 compatible with?
The YTSZH-4 is engineered exclusively for 200 mm diameter test sieves conforming to ISO 3310-1 and GB/T 6003.1. Adapters for 300 mm sieves (e.g., XSB-92 model) are not interchangeable.
Can the YTSZH-4 be used with wet sieving procedures?
No—it is strictly a dry-sieving instrument. Wet sieving requires pressurized water delivery systems and corrosion-resistant construction not present in this model.
Is calibration documentation provided with shipment?
Each unit includes a factory verification report confirming oscillation/tap frequencies and timer accuracy against internal metrological references. Full ISO/IEC 17025 calibration certificates are available upon request at additional cost.
What maintenance intervals are recommended?
Lubrication of the eccentric drive mechanism every 500 operating hours and annual inspection of motor insulation resistance and clamp torque are advised per MingShen Science Technical Bulletin MS-TB-2023-04.
Does the device meet electromagnetic compatibility (EMC) requirements for EU laboratories?
The YTSZH-4 complies with GB/T 18268.1–2010 (equivalent to IEC 61326-1), covering EMC for laboratory equipment. CE marking is not affixed as it is supplied for domestic Chinese markets; CE-compliant variants require separate certification pathways.
