This study investigates the effect of the amount and composition of cement ball mill feed on Blaine fineness and cement residue. The collected data were obtained using a ball mill for grinding clinker and additive materials (pozzolana and gypsum) at different amounts and composition of feed. The fineness of cement was measured as specific surface by air permeability method (Blaine Method) and residue was calculated as cumulated residue on a 45 microns sieve. It was found that the cement residue increased with an increase in the amount and composition of feed while the Blaine fineness decreased. The clinker particles are substantially reduced in size to generate a certain level of fineness as it has a direct influence on such performance characteristics of the final product. This study was initiated to collect significant data to establish the proper fineness and residue cement product.
