Abstract

Cement is one of the main ingredients of civil construction. In addition to Indonesia’s domestic cement production, cement production is also to meet overseas demand. Cement demand which continues to increase in production costs due to rising costs. The relatively high increase in production costs directly affected the increases in cement prices on the market so that it was necessary to increase efficiency on all lines. Efficiency that can be done is by increasing local components in the process of making cement, including the material used. The purpose of this final project research is to develop materials that can later be used as a reference for making prototype ball mill liners so that later they can substitute imports abroad and can produce their own domestically and compete with imported products. Development of material for prototype liners in ball mills uses white cast iron material through a casting process. This development aims to make white cast iron material for ball mill liners which have physical and mechanical properties in the form of high impact and hardness needed to be able to produce domestically. The chemical composition of imported white cast iron material is C = 2.55%, Si = 0.75%, S = 0.013%, P = 0.018%, Mn = 0.56%, Ni = 0.05%, Cr = 16.17%, Mo = 0%.
