Primarily used in coal, coke, limestone, sulfur iron ore, and similar materials preparation, the equipment supports critical analysis in power generation, metallurgy, geology, and chemical industries. The robust construction ensures consistent performance even with materials possessing compressive strengths up to 100 MPa.
Built with precision-machined components and a durable frame, this crusher delivers exceptional long-term reliability and low-noise operation. The unit's straightforward design reduces maintenance complexity while maximizing uptime, making it an ideal investment for demanding sample preparation laboratories.
Key Features
- Sealed Crushing Chamber: Patented sealing arrangement completely contains dust during operation, ensuring a clean lab environment and eliminating cross-contamination risks.
- Integrated Dust Extraction: A dedicated dust port connects to existing exhaust pipelines or optional standalone suction systems, efficiently removing particulates from the crushing cavity.
- Multiple Jaw Plate Materials: Choose from white cast iron, high manganese steel, alloy tool steel, ceramic, or tungsten steel to match material hardness and minimize iron contamination, extending component life.
- Low-Noise Operation: Precision-balanced eccentric shaft and heavy-duty bearings reduce vibration, achieving a quiet working cycle suitable for continuous use.
- Simple Maintenance: The modular design allows rapid jaw replacement without special tools, and the minimal parts count simplifies routine cleaning and inspection.
- Enhanced Safety: Reinforced guarding and an interlocked hopper prevent accidental access to the crushing zone, complying with international lab safety standards.
- Consistent Output Control: Adjustable discharge gap enables precise control over final particle size, ensuring reproducible results batch after batch.
- Broad Feed Compatibility: The inlet geometry accommodates blocky and irregularly shaped feed without bridging, supporting diverse sample types.
