Product Overview
This sealed hydraulic clamping sample preparation pulverizer is a heavy-duty vibratory disc mill engineered for high-energy size reduction of hard, brittle, and fibrous materials. Driven by an eccentric weight drive system, the grinding vessel executes high-frequency horizontal vibration, imparting centrifugal kinetic acceleration and intense tumbling action to internal grinding elements. Through combined high-impact collision and shear friction, bulk solid samples are rapidly transformed into homogeneous powders suitable for analytical testing.
Designed primarily for demanding industrial and research laboratories, this equipment excels at processing high-hardness raw materials, geological cores, metallurgical slag, cement clinker, soil specimens, and roasted mineral ores. Its sealed grinding vessels and automated hydraulic clamping system prevent sample loss and atmospheric contamination, making it ideal for preparing powders for X-ray Fluorescence (XRF) spectrometry, Atomic Absorption Spectroscopy (AAS), and wet chemical analysis.
Built with heavy-duty structural dampening components and high-torque motor drives, this unit delivers exceptional mechanical stability and operational reliability. It handles aggressive daily sample workloads under continuous duty cycles, ensuring highly repeatable grain size distributions while protecting lab environments from airborne dust particulates and excess noise emissions.
Key Features
- Automated Hydraulic Vessel Clamping: Features an integrated high-pressure hydraulic clamping system that automatically locks grinding bowls with uniform force. This prevents bowl dislocation during high-intensity vibration, ensuring total operator safety and consistent jar sealing.
- High-Energy Kinetic Vibration Drive: Driven by an industrial-grade motor paired with balanced eccentric weights, generating powerful horizontal gyratory forces that drive grinding rings and pucks for rapid particle breakage.
- Rapid Size Reduction Efficiency: Capable of reducing raw feed materials up to 26 mm down to uniform discharge fineness between 80 mesh and 300 mesh within 1 to 3 minutes of total grinding time.
- Contamination-Free Grinding Options: Accommodates a broad selection of specialized grinding bowl materials—including Zirconia (ZrO2), Tungsten Carbide (WC), High-Chromium Steel, Manganese Steel, and Stainless Steel—to match target sample hardness and eliminate trace-element contamination.
- Multi-Bowl High-Throughput Processing: Modular deck layout supports single-bowl large-capacity operations up to multi-bowl configurations (up to 7 bowls per batch), dramatically accelerating batch preparation cycles in busy quality control laboratories.
- Dust-Tight Sealed Enclosure: Fully sealed cabinet housing paired with hermetically sealed grinding sets minimizes fine dust escape, maintaining compliance with clean laboratory standards and safeguarding health.
- Vibration-Damped Acoustic Cabinet: Heavy-gauge steel body with internal acoustic insulation absorbs operational impact energy, minimizing workplace noise and keeping structural vibration isolated from benchtop equipment.
- Precision Digital Timer: Integrated digital timer allows precise programming of grinding durations from seconds to minutes, ensuring complete batch-to-batch consistency across shifts and operators.
