Overview
The MingShen Science FS-100 Miniature High-Speed Crusher is a compact, benchtop rotor-type grinding instrument engineered for rapid, reproducible size reduction of hard and brittle solid samples in laboratory and quality control environments. It operates on the principle of high-velocity impact and shear forces generated by a rotating stainless-steel blade within a fixed-diameter grinding chamber (100 mm). Designed for compliance with Chinese national standards (e.g., GB/T 474–2008 for coal sample preparation), the FS-100 delivers uniform particle distribution across its specified output range (0.01–0.5 mm), making it suitable for downstream analytical workflows including proximate analysis, calorimetry, X-ray fluorescence (XRF), and elemental assay preparation.
Key Features
- Compact footprint (150 × 150 × 300 mm) and lightweight design (2.9 kg) facilitate integration into space-constrained labs and field mobile units.
- 24,000 rpm brush-type motor with 480 W nominal power ensures efficient comminution of medium-hardness materials without excessive thermal buildup—provided operational limits (≤5 min continuous, ≥10 min cooling) are observed.
- Stainless-steel (2Cr13) rotor blade offers corrosion resistance and mechanical durability against abrasive feedstocks such as coal, limestone, gypsum, and cast iron chips.
- Sealed grinding chamber with positive-latching lid prevents sample loss and operator exposure during operation; interlock-compatible design discourages lid opening under power (per IEC 61000-6-2 safety guidelines).
- No external cooling or vacuum interface required—optimized for dry, low-moisture (<5% w/w) samples only; moisture or oil contamination may cause clogging, uneven milling, or motor stall.
Sample Compatibility & Compliance
The FS-100 is validated for use with dry, non-fibrous, non-sticky solid materials having Mohs hardness ≤6.5—including bituminous coal, anthracite, shale, quartz sandstone, ceramic fragments, and zinc/aluminum die-cast scrap. It is not suitable for polymers, rubber, wet biomass, or hygroscopic salts. Feed particles must be pre-sieved to <13 mm and loaded to ≤50 g per batch (recommended fill level: ≤50% chamber volume). The resulting 200-mesh (74 µm) equivalent output meets sieve analysis requirements per ISO 2591-1 and ASTM D2974 for coal and coke testing protocols. While not certified to GLP or ISO/IEC 17025 out-of-the-box, the device supports traceable sample preparation when operated within documented SOPs—including logbook entries for batch ID, feed mass, run duration, and post-run cleaning verification.
Software & Data Management
The FS-100 is a manually operated, analog-control instrument with no embedded microprocessor, firmware, or digital connectivity. It features a single-pole single-throw (SPST) toggle switch and requires no software installation, driver configuration, or cybersecurity validation. All operational parameters—including voltage (220 V AC ±10%), runtime, and cooling intervals—are governed by physical user actions and adherence to the provided operating instructions. For regulated environments (e.g., ISO 17025-accredited labs), users are expected to maintain manual logs documenting equipment calibration status (e.g., blade wear inspection frequency), maintenance history (carbon brush replacement every ~200 hr), and environmental conditions (ambient temperature <35 °C, relative humidity <70%). No FDA 21 CFR Part 11 electronic signature capability is present or implied.
Applications
- Coal preparation for ASTM D3172 (proximate analysis), ASTM D5865 (gross calorific value), and ISO 1928 (determination of gross calorific value).
- Routine crushing of geological core samples prior to geochemical digestion or XRF pellet pressing.
- Preparation of reference material homogenates in metrology laboratories performing proficiency testing.
- QC sample reduction in cement, refractory, and metallurgical product manufacturing facilities.
- Small-batch comminution for method development studies involving alternative fuels or waste-derived solid recovered fuels (SRF).
FAQ
What is the maximum recommended feed size?
Feed particles must be ≤13 mm in largest dimension; oversized material risks blade jamming and motor stalling.
Can the FS-100 process wet or oily samples?
No. Moisture or oil content exceeding 5% w/w causes adhesion to chamber walls, inconsistent particle size distribution, and potential motor overload.
How often should the carbon brushes and rotor blade be replaced?
Carbon brushes require inspection every 100 hours of cumulative operation; replacement is advised at 200 hours or upon visible wear >3 mm. Rotor blades should be rotated 180° after 50 hr and replaced after 400 hr or if chipping or dulling is observed.
Is the unit compliant with international electrical safety standards?
The FS-100 conforms to GB 4706.1–2005 (Chinese adaptation of IEC 60335-1) for household and similar electrical appliances. CE marking is not applicable; users outside China must verify local regulatory acceptance prior to deployment.
Does the crusher include documentation for audit readiness?
Yes—the supplied user manual includes maintenance checklists, torque specifications for lid fasteners, and a blank log sheet template aligned with ISO/IEC 17025 clause 6.4.2 (equipment records).
