Taylor® SS-82 / SS-82F Coarse Sieve Shaker by W.S. Tyler

Overview

The Taylor® SS-82 and SS-82F Coarse Sieve Shakers, manufactured by W.S. Tyler—a globally recognized leader in precision particle sizing instrumentation—are engineered for reliable, repeatable dry sieve analysis of coarse granular materials within the 4–400 mesh range (4.75 mm to 150 µm). These units operate on the principle of mechanical vibratory sieving, utilizing controlled horizontal circular motion combined with vertical oscillation to promote stratification and particle passage through defined aperture openings. Designed for both laboratory QA/QC environments and field-deployable applications, the shakers comply with core mechanical design conventions outlined in ASTM E11, ISO 3310-1, and USP , ensuring compatibility with standardized test sieves and traceable particle size distribution protocols. The robust cast-iron frame, precision-balanced drive mechanism, and low-vibration motor mount collectively minimize energy loss and maintain consistent amplitude across extended operation cycles—critical for inter-laboratory reproducibility.

Key Features

• Industrial-grade 1/4 HP induction motor delivering stable, low-noise vibratory energy optimized for coarse fraction separation (≥150 µm)
• Digital timer with 0.1-second resolution and programmable duration up to 99 minutes—enabling precise adherence to standardized test durations per ASTM D6913 or ISO 13320
• Universal sieve platform accommodating both 8-inch (203 mm) and 12-inch (305 mm) diameter sieve frames without tooling changes
• Modular stack configuration: supports up to six full-height or thirteen half-height 8-inch sieves; alternatively, four full-height or eight half-height 12-inch sieves
• Benchtop-mounting interface with pre-drilled, countersunk frame holes—compatible with standard lab bench clamps or permanent fastening hardware
• Electrical variants: SS-82 (115 V, 60 Hz) for North American laboratories; SS-82F (230 V, 50 Hz) for EU, APAC, and other 230 V/50 Hz regions—both certified to UL 61010-1 and CE marking requirements

Sample Compatibility & Compliance

The SS-82 series is validated for use with dry, free-flowing, non-cohesive granular samples including aggregates, ores, foundry sands, crushed rock, recycled concrete, and coarse pharmaceutical excipients. It is not intended for wet sieving, fibrous materials, or highly cohesive powders requiring sonication or air jet assistance. All sieve mounting interfaces conform to ASTM E11 Table 1 dimensional tolerances and ISO 3310-1 nominal aperture specifications. When paired with certified reference sieves (e.g., stainless steel ASTM E11 or ISO 3310-1 compliant), the system supports GLP-compliant documentation workflows and satisfies audit requirements under FDA 21 CFR Part 11 when integrated with validated electronic lab notebook (ELN) systems.

Software & Data Management

While the SS-82/SS-82F operates as a standalone electromechanical instrument without embedded firmware or network connectivity, its deterministic timing and mechanical repeatability make it fully compatible with external data capture systems. Laboratories routinely integrate these shakers into LIMS or ELN platforms via manual entry or barcode-scanned test method templates. Optional accessories—including calibrated digital timers with USB export, sieve weight tracking scales, and ASTM-compliant sample splitters—enable end-to-end traceability from sample introduction to mass-on-sieve reporting. Full calibration records, including motor RPM verification (per ISO 2591-1 Annex B) and timer accuracy validation, are maintained per ISO/IEC 17025 requirements.

Applications

• Geotechnical testing: gradation analysis of coarse aggregates per AASHTO T 27 and ASTM C136
• Mining & mineral processing: liberation analysis and crusher product sizing
• Construction materials QA: verification of asphaltic concrete gradation and sand conformity
• Environmental site assessment: soil particle size distribution for ASTM D2487 classification
• Pharmaceutical manufacturing: coarse excipient screening prior to milling or blending (USP )
• Educational labs: hands-on instruction in sieve theory, Stokes’ law limitations, and empirical particle size distribution modeling

FAQ

What sieve standards are supported by the SS-82 series?
ASTM E11, ISO 3310-1, and JIS Z 8801-1 compliant test sieves with 8-inch or 12-inch frames are fully compatible.
Can the unit be used for wet sieving?
No—this is a dry-sieving instrument only. Wet sieving requires dedicated spray nozzles, liquid containment, and corrosion-resistant construction not present in the SS-82 platform.
Is third-party calibration available?
Yes—W.S. Tyler authorized service centers provide NIST-traceable timer calibration and mechanical amplitude verification per ISO 2591-1 guidelines.
How is compliance with FDA 21 CFR Part 11 achieved?
Through integration with validated ELN/LIMS systems that enforce electronic signatures, audit trails, and role-based access control—no native software resides on the shaker itself.
What maintenance is required for long-term reliability?
Biannual inspection of motor mounts, belt tension (if applicable), and timer button responsiveness; annual verification of frame-level stability and vibration isolation integrity.
