How to calculate the actual yield of electrical cable processing

Introduction to yield in electrical cable processing

Calculating the actual yield of electrical cable processing is key to optimizing resources, reducing waste and increasing operational efficiency. Yield indicates the effective amount of material recovered in relation to the initial material, reflecting the performance of the recycling or reuse process.

Basic concepts for calculating yield

Before calculating yield, it is important to understand the main concepts involved:

• Input material: total raw electrical cables to be processed.
• Recovered material: the actual quantity of useful components obtained after processing, such as copper, aluminum or other metals.
• Losses and waste: materials discarded because they are not usable, including plastic insulation, impurities and non-recyclable fragments.

Formula for calculating actual yield

The calculation of actual yield is given by the formula:

Yield (%) = (Recovered material / Input material) x 100

This calculation gives a clear view of the percentage of raw material that has been converted into useful product.

Step by step to carry out the calculation

1. Measure the input material: weigh the electrical cables before processing to obtain the initial total mass.
2. Process the cables: carry out the separation and recycling process, removing insulators and sorting the metals.
3. Measure the recovered material: weigh the metals obtained after processing.
4. Calculate the yield: apply the formula to determine the actual percentage of recovery.

Factors influencing the actual yield

The yield can vary significantly depending on several factors, namely:

• Cable quality: the composition and condition of the cables initially processed.
• Equipment efficiency: technology and maintenance of the machines used in processing.
• Competence of operators: correct handling to minimize losses in the separation of materials.
• Control procedures: ensuring standardized processes and constant monitoring.

Tips for increasing processing performance

• Pre-sorting: identifying and separating cables with a higher metallurgical content.
• Updating equipment: using the latest technology to better separate insulators and metals.
• Train staff: continuous training for proper handling of materials.
• Implement quality control: monitor indicators and adjust processes to reduce losses.

Practical example of calculation

Suppose a batch of electrical cables weighs 1000 kg before processing. After separation and recycling, 750 kg of recovered copper is obtained. Using the formula:

Yield (%) = (750 kg / 1000 kg) x 100 = 75%

This means that 75% of the initial weight of the cables was effectively recovered as useful material.

Final considerations

Calculating the actual yield of electrical cable processing is essential for measuring the efficiency and sustainability of the process. With this evaluation, it is possible to identify opportunities for improvement, reduce costs and make the processing more environmentally friendly.
