Why do all 20 calculators have exactly four inputs?

The four visible fields are the values an engineer or supervisor is most likely to know and change for the current job. Secondary variables still exist in the underlying calculator-specific model, but they are fixed at documented values and compiled directly into the browser and workbook formulas. This keeps the form fast without hiding the basis of the answer.

Where can I see the assumptions that are not inputs?

Open the Formula and assumptions section on the calculator page or download its Excel workbook. Both surfaces list the fixed secondary values and method notes. If a disclosed value does not represent your equipment, media, utility tariff, crew, or acceptance plan, treat the result as a baseline and move to a detailed plant-specific calculation.

How should I calculate blast media required for a job?

Enter total blast area, an observed accepted-area coverage rate, the media feed rate, and measured recovery efficiency. The calculator converts area into loaded blast time, converts time into gross media circulation, and then calculates replacement demand under the disclosed initial-charge and separator assumptions. Purchase against replacement demand, not gross circulation, unless the process is intentionally single-use.

How do I check whether the compressor can support the blast setup?

Enter nozzle orifice, required nozzle pressure, simultaneous nozzle count, and compressor rated free-air delivery. The calculator estimates nozzle demand and reports the available margin after its disclosed breathing-air, auxiliary-load, duty, and reserve assumptions. Confirm final equipment selection against the compressor and nozzle manufacturers' data and measure loaded pressure at the nozzle.

How do the cost and quote calculators fit together?

Use Cost per Square Foot to normalize the accepted job cost, Energy Cost to isolate loaded compressor electricity, Operator Labor for direct crew cost, and Rework Cost for expected quality exposure. Enter the resulting labor and consolidated non-labor direct cost into Quote Margin. Keep the same job scope and accepted-area basis across the chain so costs are not omitted or counted twice.

Can these calculators certify a blasting or shot-peening process?

No. They support estimating, planning, diagnostics, and documented engineering discussion. They do not replace ventilation design, exposure assessment, lift planning, OEM selection, coating-specification acceptance, Almen saturation-curve control, inspection, or an approved quality procedure. The limitation section on each page states the boundary for that specific calculation.

Abrasive Blasting, Shot Peening & Surface Prep calculators

This hub contains 20 purpose-built calculators for abrasive blasting, shot peening, and surface preparation. Every calculator asks for exactly four job-level values, while secondary engineering assumptions remain visible in the page guide and workbook. Operators get a fast answer without a crowded form; estimators and engineers still get the method, limits, warnings, worked example, and auditable Excel formula behind it.

What this hub covers

Twenty focused abrasive-blasting, shot-peening, and surface-preparation calculators, each reduced to four decision-driving inputs with disclosed engineering assumptions.
Browse abrasive blasting, shot peening & surface prep calculators for manufacturing planning, quoting, quality, capacity, and operations decisions.

Best calculators in this category

Blast Media Consumption: Size the initial charge and fresh make-up media from actual blast area, measured production rate, media feed, and reclaim performance.
Blast Coverage Completion Rate: Separate accepted coverage completion, active production rate, and elapsed-time utilization so schedule forecasts do not mix three different measures.
Compressor Air Demand: Estimate pressure-blast compressor capacity from nozzle orifice, measured nozzle pressure, simultaneous nozzle loading, accessories, and reserve.
Blast Nozzle Wear Cost: Turn measured nozzle wear into additional airflow, energy cost, and consumed nozzle life for a defined loaded-blast interval.
Blast Room Throughput: Calculate complete-load and accepted-area capacity from the entire blast-room cycle rather than nozzle time alone.
Dust Collector Loading: Estimate captured dust mass and hopper service frequency from media breakdown and removed coating or scale—not from an arbitrary capacity percentage.
Media Reclaim Value: Value only media that is recovered, separated, and still fit for use, then subtract the operating cost of reclaim.
Surface Profile Estimate: Interpolate surface profile only between two measured shop calibration anchors and compare the estimate with the coating target window.
Shot Peening Intensity Window: Evaluate the measured saturation intensity against both specification limits and the T-to-2T saturation criterion while keeping coverage as a separate control.
Blast Cost per Square Foot: Divide a transparent full job-cost stack by first-pass accepted area rather than gross area or a generic weighted-cost preset.
Blast Air Pressure Loss: Localize loaded pressure loss between compressor, blast-pot inlet, and nozzle while separating total system loss from target shortfall.
Blast Cabinet Load Capacity: Constrain cabinet loading by both usable volume and safe fixture weight, then convert complete cycles into accepted shift output.
