Product Overview
This high-speed sealed laboratory sample preparation pulverizer is engineered for rapid, dust-free particle size reduction of brittle materials in analytical testing environments. The unit efficiently transforms raw feed samples into homogeneous fine powders ranging from 80 to 300 mesh in just 1 to 3 minutes. Designed to maintain sample integrity and prevent atmospheric contamination, this equipment serves as a vital preliminary step for accurate chemical, physical, and spectrographic analysis across demanding laboratory workflows.
Built for versatile industrial utility, the system handles diverse geological, mineralogical, metallurgical, and chemical samples. It accommodates a wide spectrum of material hardness profiles by utilizing interchangeable grinding bowl assemblies. Whether deployed in quality control laboratories, research facilities, or high-throughput production testing plants, the pulverizer delivers consistent, repeatable grinding performance tailored to precise testing protocols.
Engineered with an emphasis on operational safety and long-term durability, the pulverizer features an enclosed design that meets strict environmental protection and workspace health standards. Its heavy-duty vibratory mechanism, paired with specialized vibration-dampening mountings, ensures stable operation, low environmental noise, and minimal maintenance overhead even during continuous high-frequency sampling cycles.
Key Features
- Rapid Sample Processing: High-frequency kinetic pulverization reduces raw feed material to an ultra-fine powder of 80 to 300 mesh within an optimized 1 to 3-minute cycle time, drastically accelerating laboratory assay throughput.
- High-Velocity Kinetic Grinding Mechanism: Driven by a robust electric motor equipped with high-speed eccentric weights, the system forces internal hammers and rings into intense centrifugal vibration, delivering combined impact kinetic force and frictional shear for uniform size reduction.
- Fully Hermetic Dust Isolation: The completely sealed grinding chamber design prevents airborne particle emissions and sample loss during high-energy vibration, complying with environmental health, safety, and operational clean-air requirements.
- Extensive Bowl Alloy & Ceramic Selection: Supports a comprehensive range of grinding bowl materials—including standard manganese steel, wear-resistant alloy, high-chromium steel, tungsten carbide, alumina ceramic, and natural agate—preventing sample contamination and matching specific material hardness requirements.
- Integrated Vibration Suppression: Equipped with heavy-duty elastomeric vibration isolation pads that absorb mechanical energy, minimizing structural resonance, noise transmission, and equipment wear during high-speed rotation.
- Multi-Variant Capacity Configurations: Available in multiple batch volume designs ranging from single-chamber 400g vessels to multi-bowl arrangements capable of simultaneously processing up to four independent 100g, 200g, 300g, or 400g samples.
- Adjustable Particle Size Control: Processing duration and kinetic mass parameters can be tailored to achieve target output fineness across a wide mesh range for precise down-stream XRF, ICP, and wet chemical analysis.
