Graphite, Anode & Battery Materials Processing worked example

Dust Collection Load with dust collection system load of 28 kW: a worked example in graphite, anode & battery materials processing

Suppose dust collection system load falls to 28 kW. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate dust collection energy and cost for graphite milling, classification, coating, blending, or packaging using collector load, runtime, electricity rate, and kg processed.

The inputs for this scenario

  • Dust collection system load: 28 kW (the input this scenario stresses; the baseline uses 55)
  • Dust collection runtime: 10 hr (held at the documented default)
  • Blended electricity rate: 0.11 $ / kWh (held at the documented default)
  • Material processed under collection: 1,500 kg (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Dust collection energy cost = dust collection system load × dust collection runtime × blended electricity rate.
  • Dust collection energy used works out to 280 kWh at these inputs, and this is the headline figure for the scenario.
  • Dust collection energy cost works out to 30.8 $ at these inputs.
  • Dust collection energy cost per kg works out to 0.02 $ / piece at these inputs.
  • Hourly dust collection energy cost works out to 3.08 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where dust collection system load sits at 55 kW and the headline result is 550 kWh, this scenario comes in 49.09% below the baseline at 280 kWh.
  • It computes the electrical energy and cost of running a graphite dust collection system, and divides that cost across the material processed to give a per-kg figure. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
