Discarded Fishing Net Size Reduction Blades
“Size reduction” can refer to coarse opening, secondary cutting or screen-controlled granulation. Name the exact stage, incoming gear condition and next recovery step so unlike machines and outputs are not combined in one RFQ.

Where This Cutting Application Appears
Supplied feed and process stage
Identify the actual recovered gear rather than treating it as one polymer stream. Record net, line and rope construction; declared polymer; twine diameter; knot or braid; float, sinker, hook, cable and metal content; salt, sand, biological residue and moisture; collection method; and any prior sorting or washing. NOAA describes derelict gear as including synthetic nylon, polyethylene and polypropylene and documents collected nets being chopped in one recovery route; this does not define the customer feed or a MEIRENTE tool.
Installed process checkpoint
Map collection, sorting, attachment removal, washing or drying and each cutting stage; identify the one tool interface under review plus target range, recirculation and discharge.
Output and inspection stage
Measure the stage-specific size distribution and inspect long strands, knots, wrapping, contamination, metal strikes, fines and handoff to the next named operation.
Size Reduction process boundary
Confirm that the feed form, actual machine operation and named downstream step match this process before reviewing a replacement tool.
Size Reduction setup checkpoint
Record feed preparation, foreign-material controls, installed interface and discharge before a controlled trial.
Size Reduction acceptance checkpoint
Use customer-approved size distribution and observable defect limits on labelled samples from the same feed lot and machine settings.
Define the Required Cut Result
- Name the exact process stage on every trial record
- Report the full stage-specific output distribution
- Record strands, knots, wrapping, fines and foreign-material events separately
- Verify feeding, washing or separation at the named next step
Problems to Diagnose Before Changing the Knife
One target size is assigned to several unlike stages
Separate coarse opening, secondary cutting and granulation specifications before quoting.
Mixed net, rope and hardware cause unstable output
Sort and declare feed components instead of treating the average as one material.
Cut size is acceptable but downstream washing or feeding stalls
Review strand shape, bulk density, entanglement and discharge rather than nominal size alone.

Acceptance Criteria for a Controlled Trial
Agree how the trial will be judged before changing the knife or machine setting.
- Name the exact process stage on every trial record
- Report the full stage-specific output distribution
- Record strands, knots, wrapping, fines and foreign-material events separately
- Verify feeding, washing or separation at the named next step
Knife Forms That May Be Considered
| Possible knife form | When it may be considered | What must be confirmed |
|---|---|---|
| Existing rotor and counter-knife set from the named stage | For a documented machine and incoming condition. | Confirm rotor, seats, motion, clearance, screen and discharge from drawings. |
| Custom replacement from the original used tool and interface drawing | When a generic recycling-machine name does not establish geometry. | Confirm dimensions, wear pattern, retained sample, feed and trial method. |
Information to Send for Technical Review
You do not need to know the exact blade name. Send the available workpiece, machine, current-knife and cut-result information so the application can be reviewed against a drawing or sample.
- Gear type, declared polymers, twine or rope construction, mesh size and largest tangled mass
- Floats, sinkers, hooks, steel cable, fasteners and other attached or hidden components
- Salt, sand, biological residue, moisture, oil and prior sorting, washing or drying
- Loose, coiled, compacted or baled feed form plus dimensions and bulk density
- Named process stage, target output distribution, oversize and fines limits and downstream washing or separation step
- Existing rotor, counter-knife, granulator, screen, holder and machine-interface drawings
- Current tool plus labelled incoming feed and accepted and rejected output samples
- Trial quantity, inspection method, containment, cleaning, guarding and annual demand

Questions About This Cutting Application
Can a blade form be selected from the term “discarded fishing net” alone?
No. Confirm feed origin, construction, contamination, process stage, installed interface, current tool and accepted and rejected samples.
Can “net recycling knife” identify one tool geometry?
No. Feed preparation, machine stage and the original interface are required.
Why distinguish coarse output from granulate?
They serve different machines and downstream process needs.
Public references and scope

Supplier pages describe their own materials or equipment; they do not establish a MEIRENTE blade specification or performance claim. Confirm the actual grade, machine setup and required cut with a drawing or sample.
