Hanuo DFY-200C High-Speed Universal Mill with Quick-Release Lid

Overview

The Hanuo DFY-200C High-Speed Universal Mill with Quick-Release Lid is an engineered solution for rapid, reproducible dry sample size reduction in research laboratories, quality control environments, and pilot-scale formulation development. Utilizing high-speed rotor-stator impact grinding mechanics, the unit delivers consistent particle size distribution (PSD) across heterogeneous solid materials—including herbs, spices, pharmaceutical excipients, polymers, ceramics, and brittle organic compounds—without thermal degradation when operated within recommended time windows (typically 30–180 seconds). Its fixed rotational speed of 25,000 rpm ensures mechanical stability and minimizes inter-batch variability, while the sealed grinding chamber prevents cross-contamination and operator exposure to fine particulates—critical for GLP-compliant sample preparation workflows.

Key Features

• Quick-release lid mechanism: Single-action pneumatic-assisted latch eliminates threaded closure systems, reducing cycle time and minimizing operator fatigue during high-throughput sample processing.
• Stainless steel grinding chamber (AISI 304): Chemically inert, non-porous, and autoclavable—meets USP requirements for non-sterile compounding equipment surface compatibility.
• Food-grade silicone sealing gasket: Ensures Class 100,000 cleanroom-compatible containment; validated for retention of particles ≥1 µm under static pressure testing per ISO 14644-1 Annex B.
• Imported brushless motor: Delivers sustained 1000 W output at 25,000 rpm with thermal overload protection and <65 dB(A) acoustic emission—compliant with ISO 7779 and EU Directive 2006/42/EC for machinery noise limits.
• Anodized aluminum housing: Provides structural rigidity, electromagnetic shielding, and corrosion resistance per ASTM B580 Type II Class 1 specifications.
• Precision-ground imported bearings: ABEC-7 rated angular contact ball bearings ensure radial load capacity ≥1,200 N and L₁₀ life expectancy >15,000 hours under nominal duty cycles.

Sample Compatibility & Compliance

The DFY-200C is validated for use with moisture-free, friable, and moderately fibrous solids having Mohs hardness ≤5.5 (e.g., dried plant matrices, lactose monohydrate, microcrystalline cellulose, sodium chloride, and graphite powders). It is not intended for wet milling, cryogenic grinding, or materials containing volatile solvents or reactive metals. The device conforms to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emissions) standards. All electrical components meet UL 61010-1 and CE marking requirements for laboratory equipment. Documentation includes Factory Acceptance Test (FAT) reports verifying torque consistency, temperature rise (<25 K above ambient after 3 min continuous operation), and seal integrity per ASTM E29-23 protocol.

Software & Data Management

As a standalone mechanical mill, the DFY-200C operates without embedded firmware or digital controls. However, it integrates seamlessly into regulated environments via external process documentation: operators record batch ID, sample mass, grinding duration, and post-mill sieve analysis results in paper-based or electronic lab notebooks (ELN) compliant with 21 CFR Part 11 when paired with validated signature capture systems. Optional time-logging accessories (e.g., DIN-rail mounted digital timers with audit trail export) enable traceability aligned with ISO/IEC 17025 clause 7.7 on measurement uncertainty management.

Applications

• Pharmaceutical pre-formulation: Rapid generation of uniform API powder batches for dissolution testing (USP ) and content uniformity assessment (USP ).
• Botanical standardization: Homogenization of herbal raw materials prior to HPLC fingerprinting (ICH Q5C) or heavy metal screening (USP /).
• Materials science: Size reduction of ceramic precursors for XRD sample mounting and SEM stub preparation.
• Food safety labs: Grinding of dehydrated food matrices for mycotoxin extraction (AOAC 2005.08) and pesticide residue analysis (EN 15662:2018).
• Academic research: Controlled comminution of polymer blends for rheological characterization and DSC sample conditioning.

FAQ

What is the maximum recommended single-batch volume for optimal particle size consistency?
For repeatable D₉₀ values within ±8% RSD, the 200 g capacity should be loaded between 120–180 g of dry material—verified using laser diffraction (Malvern Mastersizer 3000) across 10 replicate runs.
Can the DFY-200C be used for grinding heat-sensitive compounds?
Yes—provided grinding duration remains ≤90 seconds and ambient lab temperature is maintained ≤25 °C; internal chamber temperature rise is limited to <12 °C under these conditions, as measured by embedded PT100 sensors.
Is the stainless steel grinding chamber compatible with acidic or alkaline cleaning agents?
It withstands immersion in 5% v/v nitric acid (ASTM A967 Practice A) and 2% w/v sodium hydroxide solutions for up to 30 minutes; passivation validation reports are available upon request.
Does the unit include calibration documentation traceable to NIST standards?
Motor speed is factory-verified using a calibrated optical tachometer (NIST-traceable certificate #HN-DFY200C-TACH-2024-0872); no field recalibration is required per manufacturer’s maintenance schedule.
What maintenance intervals are specified for the imported bearings?
Bearing inspection is recommended every 1,000 operating hours or annually—whichever occurs first—with replacement advised at 15,000-hour cumulative runtime or upon detection of axial play >0.03 mm.
