Overview
The FW400A High-Speed Universal Crusher is a benchtop laboratory crushing instrument engineered for rapid, reproducible size reduction of dry, hard, and brittle solid samples. It operates on high-speed rotor–impact mechanics: a precision-balanced stainless-steel rotor spins at 26,000 rpm, driving hardened alloy cutting blades to deliver consistent mechanical impact and shear forces against feed material within a sealed, corrosion-resistant chamber. This principle enables efficient comminution without significant thermal buildup—critical for preserving sample integrity in downstream analytical workflows such as XRF, ICP-OES, gravimetric analysis, or sieve-based particle size distribution assessment. Designed for routine use in quality control laboratories, geological survey units, pharmaceutical R&D facilities, agricultural research stations, and academic teaching labs, the FW400A meets fundamental requirements for sample homogenization prior to elemental, mineralogical, or compositional analysis.
Key Features
- Robust crushing chamber and dual-blade assembly fabricated from imported high-grade austenitic stainless steel (AISI 304), ensuring long-term dimensional stability, corrosion resistance, and minimal metallic contamination during processing.
- High-efficiency 1000 W induction motor with thermally protected windings and dynamic speed stabilization circuitry—maintains nominal 26,000 rpm under variable load conditions.
- Ergonomic tilting discharge mechanism with positive-lock hinge allows full 180° chamber inversion for complete sample recovery and rapid cleaning between batches.
- Compact footprint (230 × 190 × 420 mm) and low-noise enclosure design facilitate integration into shared lab spaces without dedicated ventilation or floor anchoring.
- Interlocked safety cover with microswitch cutoff prevents operation when chamber is open—compliant with IEC 61000-6-2/6-4 electromagnetic compatibility and basic functional safety expectations for Class I laboratory equipment.
Sample Compatibility & Compliance
The FW400A accepts feed particles up to 20 mm in maximum dimension and processes batch loads of up to 200 g per cycle. It is validated for use with granular, friable, and moderately abrasive materials including coal lumps, limestone fragments, dried plant tissue, pharmaceutical tablets, ceramic powders, and metallurgical ores. It is not suitable for fibrous, elastic, oily, or hygroscopic samples. While not certified to ISO/IEC 17025 or GLP-specific validation protocols out-of-the-box, the unit supports traceable documentation of operational parameters (batch ID, time stamp, operator ID) when integrated with external lab information management systems (LIMS). Its construction adheres to RoHS Directive 2011/65/EU restrictions on hazardous substances.
Software & Data Management
The FW400A is a standalone electromechanical device with no embedded firmware, touchscreen interface, or digital connectivity. All operational parameters—including runtime, total cycles, and maintenance intervals—are manually recorded by the user. For laboratories requiring audit trails compliant with FDA 21 CFR Part 11 or ISO 17025 Clause 7.7, integration with third-party LIMS or electronic lab notebooks (ELN) is recommended. Optional accessories include calibrated stainless-steel sieves (ISO 3310-1, aperture sizes 50–300 µm) for post-crushing particle size verification and certified reference materials (CRMs) for performance qualification.
Applications
- Pretreatment of geological core samples prior to X-ray fluorescence (XRF) or inductively coupled plasma mass spectrometry (ICP-MS) analysis.
- Homogenization of herbal medicines and botanical extracts for HPLC assay standardization.
- Size reduction of coal and coke specimens in ASTM D3174 (ash content) and D3175 (volatile matter) test preparation.
- Routine grinding of soil aggregates for nutrient extraction and heavy metal leaching studies (EPA Method 3050B).
- Preparation of calibration standards for laser diffraction particle analyzers via controlled multi-stage crushing.
FAQ
What is the minimum and maximum feed particle size the FW400A can accept?
Maximum feed size is 20 mm; particles exceeding this dimension must be pre-crushed using a jaw crusher or mortar-and-pestle. Minimum feed size is unrestricted, though sub-millimeter particles may experience reduced throughput efficiency.
Can the FW400A process wet or frozen samples?
No. The unit is designed exclusively for dry, free-flowing solids. Moisture content above 5% w/w risks blade adhesion, chamber clogging, and motor overload.
Is the output particle size adjustable?
Output fineness is governed by run time, feed hardness, and optional downstream sieving—not by internal settings. For tighter distributions, users deploy standardized test sieves after crushing.
What maintenance schedule is recommended?
Blade sharpening or replacement every 200–300 operating hours; chamber interior inspection and fastener torque verification quarterly; motor bearing lubrication annually per manufacturer service bulletin SB-FW400A-REV3.
Does the FW400A meet CE or UL certification requirements?
It carries CCC (China Compulsory Certification) marking for domestic PRC market compliance. CE marking is not affixed; UL listing is not available. Export configurations require third-party conformity assessment per destination country regulations.
