Product Overview
This sealed laboratory jaw crusher represents a significant advancement in sample preparation technology, specifically designed to address the dual challenges of efficient crushing and environmental protection. The system's core value proposition centers on its fully enclosed crushing chamber and integrated dust mitigation features, which together ensure virtually dust-free operation. This makes it an indispensable tool for laboratories where cross-contamination and airborne particulates must be tightly controlled.
Engineered for the medium and fine crushing of brittle materials, the unit excels in processing coal, coke, limestone, pyrite, and other minerals with compressive strengths up to 100 MPa. Its curved extrusion mechanism provides a steady, uniform force that minimizes the production of excess fines while maintaining high throughput. Industries such as mining, metallurgy, power generation, geology, and chemical processing rely on this equipment for reliable sample reduction.
Built with an emphasis on operational safety and longevity, the machine incorporates a robust structural frame, precision-machined components, and a simple design that facilitates quick maintenance. The addition of a dust extraction port allows seamless integration with existing lab ventilation systems, further enhancing the clean workspace. Whether in a high-volume industrial lab or a small research facility, this system delivers consistent performance with minimal operator intervention.
Key Features
- Advanced Sealing System: The fully enclosed crushing chamber employs multi-layer seals and labyrinth passages to completely contain dust, ensuring a clean lab environment and preventing cross-contamination between samples.
- Integrated Dust Extraction: A dedicated dust collection port on the crusher housing allows direct connection to existing ventilation lines or a standalone exhaust unit, effectively removing particulates from the workspace.
- Curved Extrusion Crushing Mechanism: The optimized jaw plate motion delivers high crushing forces with reduced energy consumption, producing uniform output sizes and minimal fines for accurate sample analysis.
- Comprehensive Jaw Plate Materials: Available in white cast iron, high manganese steel, alloy tool steel, ceramic, and tungsten steel, these interchangeable plates cater to diverse material hardnesses and abrasion requirements, from soft coal to tough ferroalloys.
- H-Type Environmental Upgrade: Incorporates structural reinforcements and functional extensions, including the dust exhaust feature, setting a new standard for laboratory crushing in emission-controlled environments.
- Low Noise Operation: Vibration-absorbing mounts and precision-balanced moving parts significantly reduce operational noise, contributing to a more comfortable and safer laboratory atmosphere.
- Easy Maintenance: The simple, open-frame design provides quick access to the crushing chamber and wear parts; jaw plates can be swapped in minutes without specialized tools, maximizing uptime.
- Robust Construction: Heavy-duty cast frame and heat-treated shafts guarantee dimensional stability under repeated stress, ensuring consistent performance and long service life.
- Safety Guarding: All rotating and reciprocating components are fully guarded, and an overload protection mechanism prevents damage from uncrushable objects, meeting rigorous occupational safety standards.
- Compact and Versatile: The space-efficient footprint fits easily into any lab layout, while the wide range of available models accommodates throughputs from hundreds of grams to several tons per hour.
Applications
| Application | Description | Key Benefit |
|---|---|---|
| Coal Quality Testing | Crushing of raw coal samples for proximate analysis (moisture, ash, volatile matter) in power stations and coal mines. | Dust-free operation prevents loss of volatile constituents and ensures accurate moisture determination. |
| Metallurgical Sampling | Reduction of ore, concentrates, and slag for fire assay and XRF analysis in mining labs. | Interchangeable high-manganese or tungsten steel jaws handle highly abrasive materials without excessive wear. |
| Geological Sample Preparation | Comminution of rock chip and drill core samples to fine particles for mineralogical studies. | Adjustable discharge size yields consistent particle distributions for reproducible sieve analysis. |
| Chemical and Fertilizer QC | Precise crushing of raw minerals like limestone, phosphate, and potash for chemical composition analysis. | Corrosion-resistant ceramic or alloy tool steel jaws avoid contamination of sensitive samples. |
| Environmental Analysis | Pulverizing contaminated soil, waste materials, or filter media for pollutant extraction tests. | Total containment prevents release of hazardous dusts, protecting lab personnel and environment. |
| Cement and Construction Materials | Preparing limestone, clay, and gypsum samples for quality control in cement plants. | Robust design withstands the abrasive nature of raw materials while maintaining accurate sizing. |
| Academic and Research Institutions | General-purpose sample reduction for material science experiments and teaching labs. | Simple operation and low maintenance make it user-friendly for students and multi-user facilities. |
| Industrial Minerals Processing | Crushing of silica, feldspar, and other industrial minerals for process monitoring and product certification. | Tight process control achieved through precise gap adjustment and consistent crushing force. |
