A dual-shaft shredder is purpose-built for tough metal waste reduction work in recycling facilities. This equipment uses two independently driven cutter shafts to shear, tear and compress bulky metal feedstock into uniform pieces, and it stands out as a reliable metal recycling shredder for daily scrap handling tasks. Unlike single-shaft crushing units that struggle with thick metal plates, steel fragments and mixed metallic waste, this machine adapts perfectly to high-toughness metal materials ranging from thin metal packaging to thick structural steel offcuts. Many procurement teams actively source a scrap shredder machine for sale to upgrade their metal pre-processing lines, as stable shredding output directly boosts downstream sorting and smelting efficiency.

How Does a Dual-Shaft Shredder Work?
A dual-shaft shredder operates on a simple but powerful principle: two parallel shafts arranged with interlocking blades rotate in opposite directions. When material enters the shredder, the two knife shafts rotate toward each other. The cutting discs grip the material, and the combination of pressure and shearing force tears it apart. This low-speed, high-torque approach delivers powerful cutting action with lower dust and noise than high-speed systems. The YG series metal recycling shredder uses dual motors and gearboxes to drive the two shafts independently. This independent drive provides the torque needed to handle tough materials like engine blocks, thick steel plates, and reinforced metal structures.
The PLC control system manages the entire process. When the machine encounters material that is too large or too dense, the system automatically reverses the shafts to release the overload and prevent jamming. Once the obstruction clears, the machine resumes normal operation. This auto-reverse protection is critical for maintaining uptime in high-volume recycling operations.
Core Structural Composition For Metal Shredding Scenarios
This industrial scrap metal shredder adopts a modular assembly layout optimized for metal abrasion and impact conditions, with every key component upgraded against common metal processing pain points:
1. Cutting Tool Assembly
Cutter options cover 9CrSi, Cr12MoV and SKD-11 alloy grades. 9CrSi works well for soft metal scraps like aluminum cans and thin iron sheets, while Cr12MoV and SKD-11 cold work die steel handle thick steel parts, metal furniture frames and hardened scrap with outstanding wear and impact resistance. Blade thickness is customized based on target discharge width, and blade quantity is calculated by shredding chamber length divided by single blade thickness to guarantee consistent cutting force across the full shaft length.
2. Shaft And Bearing System
Main shafts adopt carbon steel, 40CR or tempered 45# steel for strong torsional resistance under continuous metal shredding loads. Heavy-duty sealed bearing boxes block metal dust and fine scrap particles, greatly lowering daily wear during long shifts.
3. Feeding And Protective Control System
The reinforced thick steel hopper accommodates oversized metal bulk materials without deformation. The built-in PLC control system runs automatic start/stop and reverse rotation logic: when oversized metal blocks cause overload, the system triggers reverse rotation immediately to release jams and protect core mechanical parts from damage.
4. Power Drive Unit
Multiple power tiers from 4-152kw up to 4-1602kw match different metal processing volumes, paired with either standard reducers or premium planetary reducers for steady torque output during rigid metal cutting.
Advantages For Dual-Shaft Shredder
- Low Speed High Torque Operation Logic: Running at spindle speeds between 14-35r/min, the machine generates massive tearing force instead of high-speed impact. This design eliminates shaft winding and frequent jamming that plague generic shredders when processing tangled metal wires and bent steel strips, keeping continuous production running smoothly.
- Consistent Discharge Size Control: All YG models deliver final shredded metal sizes within 3- 10 cm, a universally preferred specification for subsequent magnetic separation, metal sorting and furnace feeding workflows. For projects requiring finer output, pairing two units in series is a proven industry configuration to achieve smaller particle sizes.
- Durability for Abrasive Metal Feedstock: The extra-thick welded outer frame and hexagonal heavy-duty rotating shafts absorb strong vibration produced by metal crushing. Special alloy cast moving knives hold their edge far longer than ordinary steel cutters, cutting down frequent blade replacement downtime for metal recycling operators.
- Eco-Friendly Running Status: Low rotating speed brings notably low operating noise, and sealed structural design restricts dust spread to meet environmental regulations at industrial metal recycling yards.
5 FAQs About Dual-Shaft Shredder
A1: It handles aluminum scrap, steel offcuts, scrap metal furniture, metal packaging barrels, discarded steel structural parts and mixed metallic waste perfectly, making it a highly versatile industrial scrap metal shredder across diverse recycling scenarios.
A2: Blade service life changes based on metal hardness and daily running frequency. Harder, thick steel scrap causes faster wear, while soft aluminum scrap extends usable blade life noticeably.
A3: Capacity ranges from 2 to 60 tons per hour depending on the model and material type. The YG-600 processes 2-3t/h. The YG-2600 processes 25-60t/h. Actual throughput depends on material density and feed consistency.
A4: Discharge length is calculated by cutter circumference divided by tooth count, and blade thickness sets discharge width. We customize blade specifications to hit your target metal particle dimensions.
A5:The machine includes overload protection, emergency stop buttons, and PLC-controlled auto-reverse protection. The control system monitors motor current and shaft torque to prevent damage during operation.
