High-Performance Vibrating Grizzly Bars
Product Name: Heavy-Duty Vibrating Grizzly Bars for Primary Screen Feeders
Description:
Optimize your primary crushing circuit and maximize throughput with our premium Vibrating Grizzly Bars. Positioned at the very front of your jaw or primary impact crusher, grizzly bars must endure the direct impact of massive quarry rock dumps while undergoing high-frequency vibration to scalpe out fines, dirt, and undersized aggregates.
We engineer grizzly bars with advanced metallurgies and a specialized Tapered Self-Cleaning Profile. This design ensures that smaller rocks pass through effortlessly without getting wedged, preventing costly material blinding. By upgrading to our heavy-duty grizzly bars, you protect your primary crushers from processing useless mud/fines, drastically reducing liner wear and slashing overall energy consumption.
Material Options Tailored to Your Geological Conditions:
Work-Hardening Manganese Steel (Mn13Cr2 – Mn18Cr2): The ultimate choice for high-impact quarries handling granite, basalt, or iron ore. The surface work-hardens dynamically up to HBW 500+ while the core remains flexible enough to absorb heavy boulder slams.
High-Chromium Iron / Bimetallic Structure: For highly abrasive but medium-impact applications (like quartz or hard limestone processing), delivering diamond-like sliding wear resistance.
Forged Alloy Steel with Hardfacing: Offers exceptional torsional and bending strength, with an extra welded chromium carbide layer for specific heavy-duty recycling or slag sorting.
Key Technical Highlights:
Tapered Anti-Blinding Geometry: Features a specialized structural design where the bar width narrows from top to bottom and expands from front to back. This creating a divergent gap that allows stuck stones to self-discharge under vibration.
Exceptional Rigid Securing: Engineered with precision interlocking bases or countersunk bolt slots to ensure the bars remain perfectly locked under fierce, continuous vibratory $G$-forces.
Universal Customization: Manufactured to strict drawings or OEM specifications, fully compatible with major vibrating feeder brands, including Metso Outotec®, Sandvik®, Terex Simplicity®, JCI®, and Trio®.
