Bulk Solids, Mining, Aggregates & Material Processing calculator
Crusher Throughput Calculator
Crusher Throughput estimates the net tons of on-spec product a crushing circuit actually produces once you derate gross feed for downtime and out-of-spec material. Aggregate producers and mine processing engineers use it to balance the crusher against feed and screens, plan production targets, and separate availability losses from product-quality losses. In crushing, yield is rarely 100% because oversize recirculates and fines fall outside the saleable gradation. Splitting the loss into uptime and yield tells you whether to chase mechanical availability or closed-side setting and screening.
What this calculator does
- Estimate crusher throughput for crusher throughput for bulk solids, mining, aggregates, and material processing using plant-floor material, production, quality, capacity, or cost inputs.
- 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
- 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.
Formula used
- Gross crusher throughput = crusher throughput output per cycle × available crusher throughput cycles
- Crusher Throughput = gross capacity × uptime × yield
Inputs explained
- Tonnage crushed per feed cycle:
- Crushing feed cycles available:
- Crusher running uptime:
- On-spec product yield:
How to use the result
- Use it to set a shift production target, validate a crusher against feed capacity, or quantify how much tonnage recirculation and downtime cost you.
- 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.
Common questions
- How do you calculate crusher throughput? Multiply tons per feed cycle by available cycles for gross throughput, then multiply by uptime and yield. Here 18 x 240 = 4,320 gross tons, then x 90% x 96% = 3,732.48 net product tons.
- What is a good uptime for a crusher? Mechanical availability of 85-92% is typical for primary and secondary crushers; planned liner changes pull the scheduled figure down. The 90% in the example is healthy, leaving 432 tons of downtime loss to chase.
- Why is crusher yield below 100%? Yield is the share of crushed material that meets the target gradation. Oversize that recirculates and excess fines outside spec reduce saleable product, so the 96% yield here removes 155.52 tons from the gross.
- How does closed-side setting affect throughput? A tighter setting raises reduction and fines but cuts tons per cycle and can lower yield if it overproduces fines; a wider setting raises throughput but sends more oversize to recirculation. Both shift the tons-per-cycle and yield inputs here.
- How do I increase net crusher throughput? Compare the loss lines. In the example the 432-ton uptime loss exceeds the 155.52-ton yield loss, so improving availability through choke feeding, liner management and reduced blockages returns more than tuning gradation.
