The Gilson Morse Jaw Crusher: Robust Size Reduction for Demanding Applications
In the realm of material processing laboratories and pilot plants handling hard rock samples or industrial minerals, efficient primary size reduction is paramount. Enter the Gilson Morse Jaw Crusher, a stalwart piece of equipment renowned for its exceptional strength and reliability in tackling coarse crushing tasks where lesser machines falter.
Built for Power and Endurance
The defining characteristic of the Morse Jaw Crusher lies in its robust construction:
Heavy-Duty Cast Iron Frame: Unlike lighter alloy frames common in smaller lab crushers, the Morse utilizes massive cast iron components – body frame sections and cheek plates – providing unparalleled rigidity and vibration dampening during operation.
Massive Eccentric Shaft: A large-diameter forged steel eccentric shaft forms the core of its crushing action. This substantial mass ensures smooth rotation under heavy loads and minimizes wear over extended periods.
Over-Sized Bearings: Precision anti-friction bearings are deliberately oversized relative to the rated horsepower capacity. This design philosophy prioritizes longevity and resistance to shock loads inherent in crushing hard materials.
Deep Crushing Chamber: The deep chamber geometry allows for greater feed acceptance capacity compared to many laboratory jaw crushers designed primarily for finer work.
Precision Crushing Action
The crushing mechanism leverages powerful leverage principles:
1. Powerful Stroke: The deep chamber accommodates a substantial vertical stroke at the bottom of the jaws.
2. Aggressive Nip Angle: The geometry creates an aggressive nip angle at the top of the jaws where feed material enters.
3. Forceful Crushing: Combined with high inertia from its heavy components (flywheels contribute significantly), this setup delivers powerful compressive forces capable of shattering even highly resistant materials like granite or quartzite efficiently.
4. Adjustable Output: Particle size output is controlled via an easily adjustable gap setting between the fixed jaw plate (integral with the frame) and the swinging jaw plate attached to the pitman arm driven by the eccentric shaft.
Core Applications: Where Strength Matters
The Gilson Morse Jaw Crusher excels in scenarios demanding brute force:
Primary Crushing Hard Rock Samples: Reducing large chunks (often up to 4×6 inches) of ore cores or field samples down to manageable sizes (e.g., 1/4 inch minus) for subsequent pulverizing or analysis.
