Heavy-Duty Metal Shredder Grates

Product Name: Cast Manganese Steel Shredder Grates for Scrap & Auto Recycling Lines

Description: Ensure maximum throughput and flawless material sizing with our ultra-premium Metal Shredder Grates (Bottom Grates & Top Grates). Positioned at the very base of mega-watt recycling shredders, the grates serve as the final sizing barrier. They must endure catastrophic, continuous pounding from heavy hammers slamming shredded cars, structural scrap, and appliances against their surfaces until the metal is dense enough to pass through.

We specialize in casting heavy-duty, fracture-immune shredder grates engineered from advanced work-hardening manganese steel and proprietary low-alloy steel formulas. Designed with optimized radiuses and reinforced structural webbing, our grates prevent bowing, plugging, and premature cracking. Upgrade your shredding operation to achieve premium-grade scrap density, consistent output sizing, and drastically fewer emergency maintenance shutdowns.

Available Configurations for Shredding Rotors:

• Bottom Grates (Solid & Standard Hole): Positioned at the discharge floor, available in staggered or inline hole arrays optimized for clean scrap classification.

• Top & Double-Beam Grates: Engineered with thicker profiles to bear the initial brutal impact in the upper chamber.

• Intake & Spacer Grates: Precision cast to maintain structural alignment and flawless integration with the side liners.

Key Technical Highlights:

• Work-Hardening Superstructure: Cast from premium Manganese Steel (Mn13Cr2 or Mn18Cr2). The surface rapidly work-hardens under massive metallic impacts from HBW 220 to HBW 520+, while the interior core remains ductile and completely immune to brittle snapping.

• Anti-Plugging Relieved Hole Design: Features a specialized tapered/relieved design where the grate openings are slightly wider on the discharge side. This ensures that compressed metal fragments pass through smoothly without getting wedged or blinding the grate.

• Exact OEM Match: Engineered to tight dimensional tolerances, offering seamless drop-in replacements for major global metal shredder brands, including Metso Lindemann®, Texas Shredder®, Newell®, Wendt®, and Danieli®.
