SS120 Blade All Metal Mini Shredder Head | 65Mn Manganese Steel

1. Basic Product Information

2. Upgrade Comparison (SS100 VS SS120)

• Feeding Inlet: SS120 widened feeding inlet ensures smoother feeding and reduces material blocking probability.
• Blade Tooth Structure: Upgraded from 3-tooth blade of SS100 to 5-tooth blade, greatly improving shredding efficiency.
• Main Shaft Specification: Main shaft diameter upgraded from 15mm (SS100) to 24mm, supporting shredding of harder and thicker materials.
• Blade Quantity: Blade groups increased from 10 sets to 15 sets, effectively improving single-time processing capacity and working efficiency.
