Work out blasting media consumption instantly with clear inputs, formula shown and shareable results.
Total media thrown is area times the consumption rate for the required surface profile, typically 20-40 kg/m² for a blast-clean to a near-white standard. In a recovery system only the fraction that breaks down has to be replaced, so fresh media is the total multiplied by one minus the recovery rate. Nozzle flow sets how long the job takes.
Media thrown
kg = area m² x consumption rate kg/m²
Fresh media
kg fresh = total x (1 - recovery rate); hours = total / nozzle flow
kg = area m² x consumption rate kg/m². Total media thrown is area times the consumption rate for the required surface profile, typically 20-40 kg/m² for a blast-clean to a near-white standard.
Without recovery every kilogram thrown is bought once and disposed of once. Recyclable steel grit lasts hundreds of cycles, which is why enclosed blast rooms use it despite the higher unit price.
This calculator takes 4 inputs: Area to blast, Media consumption rate, Media recovery rate, Nozzle media flow. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
