Raw Mix Design Calculator

Proportion limestone, clay, iron ore & additives to achieve target LSF, SM, and IM — with Bogue compound prediction

How to Use This Calculator

  1. Enter oxide analysis for each raw material: check enable box to include (limestone, clay/shale, iron ore, bauxite, sandstone)
  2. Set target quality parameters: LSF 95-108, SM 2.0-3.0, IM 1.3-2.0
  3. Enter fuel data for ash absorption correction: specific heat consumption, NCV, ash content
  4. Click Calculate: see optimal proportions, raw meal composition, clinker oxides, Bogue compounds, and liquid phase
