Product Overview
This openable sealed jaw crusher represents an advanced, high-purity sample preparation solution engineered specifically for contamination-free size reduction of hard, brittle, and ultra-pure materials. Built with premium zirconia ceramic jaw plates and a swing-open crushing chamber, the system completely prevents metal ion leaching during primary and intermediate crushing steps. It addresses the rigorous operational demands of modern analytical laboratories where sample purity, repeatability, and absolute protection against cross-contamination are paramount.
Tailored for research laboratories, quality control facilities, and pilot-scale industrial environments, this unit excels at processing high-value materials including lithium battery precursors, rare earth oxides, electronic ceramics, polysilicon, and geological minerals. The integrated dust-tight housing—featuring high-density polypropylene (PP) or grade 304 stainless steel feeding and discharge ports—effectively contains airborne dust. This ensures complete sample recovery while safeguarding laboratory personnel from airborne particulates.
Constructed to maintain mechanical stability under demanding crushing loads, the equipment features a heavy-duty eccentric shaft mechanism and precision drive components. The open-chamber architecture allows operators to open the stationary jaw assembly within seconds, providing unobstructed access for visual inspection, thorough cleaning, and rapid maintenance between consecutive analytical batches.
Key Features
- Zero Metal Contamination Ceramic Linings: High-purity zirconia jaw plates eliminate metallic ion contamination during crushing operations, ensuring absolute elemental integrity for sensitive chemical, semiconductor, and battery material testing.
- Rapid-Access Openable Chamber Design: The stationary jaw housing swings open effortlessly via a quick-release mechanism, enabling complete visual inspection and rapid, residue-free cleaning between batch samples.
- Dust-Tight Environmental Containment: Engineered with custom polypropylene (PP) or AISI 304 stainless steel inlet and discharge interfaces combined with a fully sealed outer body, the unit prevents particulate leakage and maintains cleanroom hygiene.
- Continuously Adjustable Discharge Gap: Discharge particle size can be easily calibrated across a broad range, allowing precise control over final sample granulometry to suit downstream grinding or analytical requirements.
- High Reduction Ratio Mechanical Dynamics: Balanced eccentric shaft geometry delivers exceptional crushing force and high reduction ratios, easily handling tough feed materials up to 120 mm and reducing them down to uniform fine fractions.
- Corrosion and Wear-Resistant Contact Surfaces: All internal contact zones feature chemically inert, high-hardness ceramics or stainless alloys, resisting aggressive chemical degradation and abrasive physical wear.
- Vibration-Damped Industrial Motor Drive: Equipped with high-torque motor systems and balanced flywheels, the crusher operates with minimal noise and reduced structural vibration, ensuring long mechanical service life.
