Ball milling duration has an important role in the synthesis of calcium nanoparticles. The duration of this process can influence the properties of the calcium powder. This study investigates the influence of ball milling duration on the physicochemical properties and compressibility of snail shell powder. Morphology of the samples shows agglomeration with irregular shape. The elemental composition of samples mostly calcium (Ca). The phases formed in the samples are Ca(OH)₂, the smallest crystallite size of 21.11 nm. The observed functional groups result shown C-O vibrations of the CO₃^2- carbonate group, Ca-O bonds. The compressibility test shows that the sample with 9 hours milling time has the largest compressibility. Based on the research conducted, it shows that milling time has an influence on the properties of snail shell powder.
