Scrap Chopper for Metallurgical Processing Lines
The scrap chopper cuts the waste edge coming off the trimming section so it can be collected and recycled. Waste edge passes from the chute into the chopper and drops into the waste box as short broken pieces.
- Double roller type with left and right racks
- Upper knife shaft is the active shaft
- Motor, reducer and coupling on each side
- Upper shaft drives the lower shaft through gear
Key Benefits
Why every trimming line needs one.
Continuous Scrap Removal
Chopping the waste edge as it is produced lets the trimming section run without stopping to clear scrap.
Recycling Made Practical
Short chopped pieces in a waste box are far easier to collect and recycle than long ribbons of edge.
Balanced Handling Of Both Edges
Left and right racks with independent drives handle both trimmed edges at the same rate.
Where It Is Used
Line positions.
- Behind side trimmers on slitting lines
- Pickling line trimming sections
- Cut to length lines with edge trimming
- Any metallurgical line producing edge scrap
Who It Is For
- Metallurgical plant maintenance teams
- Slitting and trimming line operators
- Line builders supplying trimming sections
- Buyers upgrading scrap handling
Problems It Solves
- Edge scrap jamming the chute
- Trimming line stopping to clear scrap
- Manual scrap handling
- Bulky scrap that is hard to collect
Technical Features
Machine arrangement.
Double Roller Construction
Two racks, left and right, each handle the shear strip from one side of the line.
Upper And Lower Knife Shafts
Each rack carries upper and lower knife shafts with the upper shaft driven.
Independent Drives
Left and right upper knife shafts are driven separately, each with motor, reducer and coupling.

Manufacturing Process
Scrap Data Review
Trimmed edge width, thickness, material and line speed define the machine.
Rack Fabrication
Racks are welded and machined for knife shaft alignment.
Shaft And Knife Production
Knife shafts and knives are produced and hardened.
Assembly And Run Test
Drives are fitted and the chopper is run tested before shipment.
Quality Control
- Rack machining and alignment inspection
- Knife hardness verification
- Gear mesh check
- Drive function test per side
Customization Options
- Capacity for your edge dimensions
- Drive rating to line speed
- Chute and waste box interface
- Layout to suit the existing trimming section
Use Guide
- Keep the chute clear and evenly fed
- Inspect knives at planned intervals
- Check gear lubrication on both shafts
- Empty the waste box before it backs up
How It Compares
Against other scrap handling methods.
| Scrap coilers | Chopping avoids handling and storing long coils of edge scrap. |
|---|---|
| Manual handling | Continuous chopping keeps the line running and the operator away from the scrap path. |
| Single side units | Left and right racks with independent drives handle both edges at matched capacity. |

Scrap Chopper for Metallurgical Lines FAQ
What does the chopper do?
It chops the waste edge from the trimming section so it can be collected and recycled. Edge scrap passes from the chute into the chopper and the broken pieces fall into the waste box.
How is it driven?
It is double roller type with left and right racks. Each side has its own motor, reducer and coupling on the upper knife shaft, which drives the lower shaft through gear.
Can it be fitted to an existing line?
Yes. Send the trimmed edge dimensions, material, line speed and the chute layout.
What maintenance is needed?
Knife inspection and regrinding or replacement at intervals set by your material, plus gear lubrication and drive checks.
Do you supply replacement knives?
Yes, knives and knife shafts are available as spares for the machines we build.
What do you need to quote?
Trimmed edge width and thickness, material, line speed and the space available at the trimming section.
