Supplementary data A: Compacted density, bimodal optimal composition, fractional packing density, and Cooper-Eaton modelling of briquette made with Indonesian middle-rank coal

This dataset contains compaction data of briquette made from binary mixture of Indonesia middle-rank coal with different mass fraction of small and large particles. Density of briquette was measured using caliper while being pressed inside the dies during uniaxial briquetting. Based on each density, the compaction characteristics of each mixture was analyzed using Cooper-Eaton curve-fitting model. Curve-fitting was performed using Solver Add-Ins in Microsoft Excel 2016.<br>Bimodal optimal composition, fractional packing density and coordination number of the bulk mixture at 0.002 MPa were calculated based on the formula found on R.M. German researches on Powder Metallurgy.<br>Inside the xlsx file, spreadsheets of pressed density, bimodal mixture optimal composition, fractional density and average coordination number at 0.002 MPa, example of curve-fitting operations, compaction characteristics from Cooper-Eaton model, and the regression quality (R²) could be found.
