Gilson TS-1 / TS-1F / TS-2 / TS-2F / TS-3 / TS-3F / TS-4 Series Testing Screens

Overview

The Gilson TS-Series Testing Screens are precision-engineered mechanical sieving systems designed for rapid, reproducible particle size analysis of coarse granular materials—including aggregates, slag, ores, crushed rock, and construction-grade mineral feedstocks. Operating on the principle of controlled horizontal circular motion (rotary sieving), these units comply with standardized test methods defined in ASTM C136/C136M (Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates) and ISO 2591-1 (Particle Size Analysis — Sieving — Part 1: Manual Sieving). Each model delivers consistent amplitude (8 mm nominal) and frequency (270–300 rpm) optimized for efficient stratification and separation across the 101 mm (4 in) to 4.75 mm (No. 4 sieve) range—covering the full scope of coarse aggregate gradation testing. The sealed, oil-free drive assembly houses a robust 0.5 HP capacitor-start induction motor with built-in thermal overload protection, ensuring stable operation under continuous laboratory or QA/QC production-line duty cycles.

Key Features

• Modular tray architecture supporting up to seven independent sieve trays (TS-3/TS-4 models) or six (TS-1/TS-2 series), accommodating standard ASTM E11 or ISO 565 compliant woven wire cloth, perforated steel plates, or custom mesh inserts.
• Hydraulic clamping system (TS-1/TS-1F/TS-3/TS-3F/TS-4) enabling sub-10-second tray engagement and release via single-lever actuation—reducing operator fatigue and improving inter-test consistency.
• Manual screw-clamp option (TS-2/TS-2F) offering cost-effective operation with full mechanical adjustability; compatible with optional hydraulic conversion kits (TSA-155/TSA-159) for field upgradeability.
• Integrated acoustic damping enclosure (TS-4 only): triple-layer composite door gasketing, ferrite-magnet retention system, and internal sound-absorbing lining reduce operational noise to ≤68 dBA at 1 m distance—meeting ISO 7779 and OSHA 29 CFR 1910.95 workplace exposure guidelines.
• Digital LED timer (TS-4 standard; optional TSA-169R for other models) supports four programmable modes: fixed duration (1–99 min), interval cycling, auto-stop on completion, and continuous run—with audit-trail-capable logging when paired with GLP-compliant data acquisition software.
• Universal voltage compatibility: 115 V / 60 Hz (North America, Japan) and 230 V / 50 Hz (EU, UK, Australia) variants available per model, with CE, UL, and CSA safety certifications pre-validated.

Sample Compatibility & Compliance

The TS-Series accommodates batch volumes up to 1 ft³ (0.028 m³), enabling statistically representative sampling per ASTM D75 and AASHTO T 27 requirements. Tray depth options—including standard 4-inch, shallow 3-inch, and angled chutes—support both dry sieving and fine-fraction recovery workflows. All sieve trays utilize replaceable mesh inserts conforming to ASTM E11 Class W (woven wire) or Class P (perforated plate) tolerances, with aperture sizes ranging from 200 µm to 101 mm. Optional accessories—including TSA-156 stackable tray racks, TSA-167 net weight attachments for rapid post-sieve mass determination, and TSA-180 freestanding acoustic enclosures—extend functionality without compromising regulatory traceability. Units are designed for permanent floor-mount installation using M12 anchor bolts into reinforced concrete substrates (minimum compressive strength: 25 MPa), satisfying ISO 17025 clause 6.3.2 for equipment stability and vibration isolation.

Software & Data Management

While the base TS-Series operates as a standalone electromechanical instrument, integration with Gilson’s G-Link™ Laboratory Data Management Suite (v4.2+) enables full 21 CFR Part 11 compliance. This includes electronic signatures, role-based access control, automated timestamped test logs, and immutable audit trails for all sieve sequence parameters (duration, amplitude, tray configuration, operator ID). Raw mass distribution data exports directly to CSV, Excel, or LIMS-compatible XML formats. Optional TSA-169R digital timers feature RS-232 output for real-time synchronization with external balances or spectrometers in automated QA workflows.

Applications

• Quality assurance of coarse aggregates in asphalt and concrete batching plants (ASTM C33, EN 12620).
• Mineral processing plant feed characterization and mill circuit optimization (SAG/ball mill feed sizing).
• Geotechnical soil classification per USCS and AASHTO M 145 protocols.
• Recycled construction and demolition debris (C&D) fractionation verification.
• R&D screening of novel composite fillers, catalyst supports, or pharmaceutical granules where mechanical robustness exceeds vibratory shaker limitations.

FAQ

What voltage configurations are supported across the TS-Series?
All models are available in dual-rated variants: 115 V ±10%, 60 Hz (NEMA 5-15P plug) and 230 V ±10%, 50 Hz (CEE 7/7 or BS 1363 plug), with internal motor windings optimized for each region.
Can I retrofit my existing TS-2 unit with hydraulic clamping?
Yes—TSA-155 (for serial numbers ≤13825) and TSA-159 (≥13826) conversion kits include all mounting hardware, hydraulic cylinder, pump manifold, and pressure-relief valve; installation requires no structural modification.
Are sieve trays interchangeable between TS-Series models?
Yes—all TS-Series units share identical tray dimensions (305 × 305 mm), slot pitch, and clamping interface geometry; ASTM E11 and ISO 565 mesh inserts are fully cross-compatible.
Does the TS-4 meet ISO 17025 environmental monitoring requirements?
Its integrated acoustic enclosure, dust-sealed door gasketing, and low-vibration frame design satisfy ISO/IEC 17025:2017 clause 6.3.2 for environmental condition control during testing—particularly relevant for accredited aggregate testing laboratories.
What maintenance is required for the hydraulic system in TS-1/TS-4 units?
The closed-loop hydraulic circuit uses ISO VG 32 mineral oil; annual fluid inspection and replacement (every 2,000 operating hours) is recommended, along with quarterly visual checks of hose integrity and clamp piston seal condition.
