Belt Speed Requirement at 99% belt speed requirement uptime: a worked example

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

The inputs for this scenario

  • Belt Speed Requirement output per cycle: 18 tons / cycle (unchanged)
  • Available belt speed requirement cycles: 240 cycles (unchanged)
  • Belt Speed Requirement uptime: 99 % (raised for this scenario; the documented default is 90)
  • Belt Speed Requirement first-pass yield: 96 % (unchanged)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where belt speed requirement 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 computes deliverable tonnage by multiplying output per cycle and available cycles, then derating for belt uptime and first-pass yield. 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.

Results at a glance

  • Belt Speed Requirement: 4,106 tons (headline result)
  • Gross belt speed requirement: 4,320 tons
  • Belt Speed Requirement uptime loss: 43.2 tons
  • Belt Speed Requirement yield loss: 171 tons
