Smart Hydraulic Vertical Saled Nitrogen Filled Single Shaft Shredder for Crushing Shredding Recycling Flammable Solid Waste Lithium-Ion Battery Plastics Machine

Yes. The nitrogen-inerted environment prevents thermal runaway that normally occurs when charged batteries are mechanically damaged. While pre-discharging is recommended for optimal black mass recovery, our system safely processes charged cells and modules that conventional shredders cannot handle. The oxygen-depleted chamber (typically below 3% O2) ensures that any sparks generated during cutting cannot sustain combustion.

We recommend nitrogen purity of 99.9%. Consumption ranges from 5-15 Nm3/h during continuous operation, depending on model size and material type. The system accepts nitrogen from cylinder banks, liquid nitrogen vaporizers, or on-site PSA/membrane generators. The PLC automatically controls nitrogen flow based on real-time oxygen sensor readings to minimize waste.

Blade life depends on material abrasiveness and operating hours. For lithium battery applications, D2 blades typically last 800-1,200 hours before resharpening, while DC53 blades offer 1,200-1,800 hours. Each blade features 4 usable cutting edges that can be rotated in place before replacement, effectively multiplying service life by 4*.

Yes. The standard screen range is 8-50 mm, but custom apertures are available upon request. The hydraulic screen cradle system allows rapid screen changes without breaking the sealed chamber atmosphere, enabling you to switch between different particle sizes for different downstream processes.

Yes. We offer an optional ATEX Compliance Package that includes explosion-proof motors, intrinsically safe sensors, certified control panels, and documentation meeting EU Directive 2014/34/EU requirements. This configuration is recommended for operations in potentially explosive atmospheres where formal certification is mandatory.
