Crusher Throughput at 99% crusher running uptime: a worked example

Push crusher running uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. a plant team is reviewing crusher throughput for bulk solids, mining, aggregates, and material processing and needs a clear crusher throughput for production, quality, capacity, maintenance, purchasing, or costing decisions

The inputs for this scenario

  • Tonnage crushed per feed cycle: 18 tons / cycle (unchanged)
  • Crushing feed cycles available: 240 cycles (unchanged)
  • Crusher running uptime: 99 % (raised for this scenario; the documented default is 90)
  • On-spec product yield: 96 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross crusher throughput = crusher throughput output per cycle × available crusher throughput cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,106 tons for crusher throughput, the number this scenario is built around.
  • At this operating point the engine returns 4,320 tons for gross crusher throughput.
  • At this operating point the engine returns 43.2 tons for crusher throughput uptime loss.
  • At this operating point the engine returns 171 tons for crusher throughput yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where crusher running uptime sits at 90% and the headline result is 3,732 tons, this scenario comes in 10% above the baseline at 4,106 tons.
  • It multiplies tons per feed cycle by available cycles for gross throughput, then derates by crusher uptime and on-spec product yield to give net saleable tons. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
