Crusher Throughput at 65% crusher running uptime: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop crusher running uptime to 65%, then walk the calculation through step by step. Estimate crusher throughput for crusher throughput for bulk solids, mining, aggregates, and material processing using plant-floor material, production, quality, capacity, or cost inputs.

The inputs for this scenario

  • Tonnage crushed per feed cycle: 18 tons / cycle (held at the documented default)
  • Crushing feed cycles available: 240 cycles (held at the documented default)
  • Crusher running uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • On-spec product yield: 96 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross crusher throughput = crusher throughput output per cycle × available crusher throughput cycles.
  • Crusher Throughput works out to 2,696 tons at these inputs, and this is the headline figure for the scenario.
  • Gross crusher throughput works out to 4,320 tons at these inputs.
  • Crusher Throughput uptime loss works out to 1,512 tons at these inputs.
  • Crusher Throughput yield loss works out to 112 tons at these inputs.

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 27.78% below the baseline at 2,696 tons.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to crusher running uptime, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a steady feed and a single yield figure. Real crushers see throughput swing with feed gradation, closed-side setting, liner wear and choke-feed quality, which one yield number cannot fully represent.

Results at a glance

  • Crusher Throughput: 2,696 tons (headline result)
  • Gross crusher throughput: 4,320 tons
  • Crusher Throughput uptime loss: 1,512 tons
  • Crusher Throughput yield loss: 112 tons
