Laboratory Jaw Crusher
Capacity: 50-500 KGPH
Feeding Size: ≤50 mm
Discharging Size: 3-20 mm
Handling Materials: Gold mine, iron mine, copper mine, limestone, quartzite, concrete block, ceramics, etc
Laboratory jaw crusher prepares rock/ore samples (≤50mm) for analysis, reducing them to 3–20mm at 50–500kg/h. Ideal for mining and geology labs, it offers adjustable discharge settings and low dust emission. Avoid ultra-hard (>8 Mohs) or sticky materials.
Advantages
01.
Precise Crushing
Adjustable jaw gaps (3–20mm) enable customizable output sizes for consistent sample preparation, critical for assay accuracy.
02.
Compact Design
Benchtop models (50–80kg) save lab space while handling ≤50mm feed, ideal for confined workspaces.
03.
Low Contamination
Hardened steel jaws (HRC60+) minimize wear debris, ensuring sample purity for sensitive analyses like gold fire assay.
04.
Easy Maintenance
Quick-release jaw plates replace in <5 minutes, reducing downtime between material changes (e.g., switching from ore to ceramics).
How Does A Laboratory Jaw Crusher Work
1. Material Loading: Samples (≤50 mm) are fed into the crushing chamber between a fixed jaw and a movable jaw, manually or via a funnel.
2. Compression Crushing: The movable jaw reciprocates (eccentric drive at 200–500 RPM), applying cyclic pressure to fracture particles against the fixed jaw.
3. Size Reduction: Particles are progressively crushed until small enough to pass the adjustable discharge gap (3–20mm), governed by the "nipping angle" (18°–22°).
4. Product Discharge: Crushed material falls freely by gravity, while dust is contained via sealed chambers or connected extraction systems.
