Small Laboratory Jaw Crusher 125x100mm Feed Opening for Sample Preparation

Product Overview

This laboratory jaw crusher is a compact, high-efficiency sample preparation tool designed for medium to fine crushing of brittle, medium-hard materials. Employing a curved extrusion crushing mechanism, it reliably reduces raw samples to uniform particle sizes with minimal fines, making it an essential first step in any analytical workflow. Its robust construction and straightforward operation deliver consistent performance even under continuous use.

Engineered for versatility, this unit handles a wide range of materials—including coal, gangue, coke, limestone, and pyrite—with a maximum compressive strength of 100 MPa. It is the go-to solution for quality control, research, and process monitoring in industries such as power generation, metallurgy, chemical processing, and geology. The adjustable discharge size allows operators to tailor output granularity to downstream testing requirements.

Built for demanding laboratory environments, this system prioritizes operator safety and low maintenance. A sealed crushing chamber eliminates dust leakage, while the optimized mechanical design reduces noise and vibration. With few moving parts and easy access for jaw plate replacement, it ensures long-term reliability and minimal downtime, giving procurement teams confidence in their investment.

Key Features

• Curved Extrusion Crushing: The moving jaw plate follows a compound pendulum motion, applying high-pressure compressive forces to efficiently fracture materials. This geometry maximizes throughput while protecting the crusher from unbreakable objects.
• Precision-Adjustable Discharge: A convenient adjustment mechanism allows the output particle size to be set below 15 mm, ensuring reproducible sample preparation suited to various analytical methods like XRF, titration, and sieve analysis.
• Dust-Free Operation: Fully enclosed crushing chamber with integrated seals prevents airborne particulate release, maintaining a clean working environment and meeting occupational health standards.
• Quiet Performance: Optimized drive system and heavy castings dampen operational noise, making this unit compatible with sensitive lab settings without requiring additional acoustic enclosures.
• Interchangeable Jaw Plates: Choose from white cast iron (for general use), high manganese steel (for tough materials), or wear-resistant alloy (for extended service life). Custom plate options are available upon request to match specific sample properties.
• Simple, Robust Construction: Minimal components and a straightforward bolted frame design facilitate rapid disassembly, cleaning, and maintenance, reducing life-cycle costs.
• Energy-Efficient Motor: The 3 kW motor provides ample torque for starting under load while maintaining low power consumption during continuous operation.
• Wide Material Compatibility: Effectively crushes materials up to 100 MPa compressive strength, covering the majority of geological, mineral, and industrial samples.
