Product Overview
This high-performance laboratory jaw crusher is an essential sample preparation system designed for the primary and fine size reduction of tough, brittle, and medium-hard materials. Utilizing an advanced curved extrusion mechanism, the unit drives a dynamic jaw plate against a fixed jaw via an eccentric shaft assembly. This mechanical action generates immense compressive force, allowing the system to achieve exceptional reduction ratios while maintaining absolute particle size control across laboratory testing and pilot-scale industrial workflows.
Engineered for versatility across rigorous processing environments, the equipment handles raw input feed sizes up to 350 mm and processes materials with compressive strength up to 1,500 kg/cm² (320 MPa). Target industries include mining, geology, metallurgy, optical glass manufacturing, polysilicon production, power plant fuel testing, and advanced materials research. Whether deployed in laboratory quality control or high-throughput sampling stations, this equipment delivers predictable, batch-to-batch consistency.
Built with structural rigidity and long-term durability in mind, the unit features customizable alloy linings, simplified gap adjustment mechanisms, and dust-sealed bearing housing assemblies. The heavy-duty frame absorbs operational vibrations during continuous crushing of dense iron ores, gangue, or technical ceramics. This combination of mechanical robustness and refined precision guarantees reliable operational availability and minimal maintenance overhead under demanding industrial conditions.
Key Features
- Curved Extrusion Crushing Kinematics: Driven by a precision eccentric shaft, the dynamic jaw plate executes a continuous curved squeezing motion that delivers uniform force distribution and efficient size reduction for high-hardness materials.
- Customizable Wear-Resistant Jaw Plates: To eliminate cross-contamination and match specific abrasive properties, jaw plates are available in high manganese steel, tungsten carbide, zirconium oxide, chromium steel, and technical ceramics.
- Adjustable Discharge Gap Control: Equipped with a wide discharge opening setting range, allowing operators to fine-tune output particle sizes precisely to meet strict downstream sieving and analytical requirements.
- High Compressive Resistance: Specifically engineered to process hard and extra-hard feed stock with compressive strengths up to 1,500 kg/cm² (320 MPa), including iron ore, limestone, and hard coal.
- Heavy-Duty Cast and Welded Construction: Manufactured with a reinforced frame structural design and high-inertia flywheels that minimize mechanical stress and maintain smooth rotational velocity under peak impact loads.
- Clean and Loss-Free Processing: Designed with sealed crushing chambers and smooth material flow geometry to minimize sample retention, preventing cross-batch contamination in analytical labs.
- Simplified Maintenance and Operation: Features easily accessible grease lubrication points, user-friendly gap calibration controls, and modular wear parts that can be swapped quickly during routine servicing.
