In a cable recycling line, the objective of cutting is to facilitate the release of the conductor and its separation from the insulation. Reducing the size without controlling the result can generate losses of metal or a plastic fraction that is difficult to recover. Cable recycling blades must be chosen within that process balance.
Sort the cable before feeding
A batch of thin wire does not behave the same as armored wire, harnesses, or greasy material. Record the type of conductor, insulation and elements outside the normal flow. The acceptance of each waste must correspond to the plant design. Metal parts that are not part of the intended material can damage tools and alter subsequent separation.
The function of each reduction stage
ELDAN describes modular solutions for cable recycling that allow additional stages to be incorporated depending on the application. In terms of process, pre-shredding prepares the material and granulation approximates the release needed to separate. The specific configuration, including separators and classification, must be sized by testing. There is no universal size that works for all cable mixes.
Check the result, not just the flow
Compare samples of the metal concentrate and the insulation fraction. Record impurities, recovered metal, recirculated material, and downtime. If purity drops, check inlet and separation as well as mill. Changing just blades may not solve the problem. A test with known composition helps to locate at which stage stability is lost.
Spare parts that should be reviewed together
In addition to knives and bedknife, inspect screens, knife holders and fixings according to the maintenance plan. Housing wear can affect the performance of a new blade. Identify the replacement by reference and actual equipment configuration, including previous modifications. Plan for availability of a validated cutting assembly prior to the maintenance outage.
Frequently asked question
Does finer granulation always recover more copper?
No. Size must balance release, separation, and loss. Contrast output fractions through plant trials before changing configuration.
