Graphite, Anode & Battery Materials Processing worked example

Dust Collection Load with dust collection system load of 140 kW: a worked example in graphite, anode & battery materials processing

This scenario runs the dust collection load calculation on the strong side: dust collection system load of 140 kW, with every other input held at its documented default. Use it when combustible dust control, fine graphite capture, filter loading, or collector operating cost needs to be included in process planning or quoting.

The inputs for this scenario

  • Dust collection system load: 140 kW (raised for this scenario; the documented default is 55)
  • Dust collection runtime: 10 hr (unchanged)
  • Blended electricity rate: 0.11 $ / kWh (unchanged)
  • Material processed under collection: 1,500 kg (unchanged)

Working through the calculation

  • Applying the documented formula (Dust collection energy cost = dust collection system load × dust collection runtime × blended electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,400 kWh for dust collection energy used, the number this scenario is built around.
  • At this operating point the engine returns 154 $ for dust collection energy cost.
  • At this operating point the engine returns 0.1 $ / piece for dust collection energy cost per kg.
  • At this operating point the engine returns 15.4 $ / hr for hourly dust collection energy cost.

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 155% above the baseline at 1,400 kWh.
  • Use it when allocating dust-control energy to product cost, evaluating a variable-speed-drive retrofit on the collector fan, or comparing collection efficiency between mills or grinding cells. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
