    The manufacture procedures of Portland cement is described below. Mixing of raw material. Burning. Grinding. Storage and packaging. 1. Mixing of raw material. The major raw materials used in the manufacture of cement are Calcium, Silicon, Iron and Aluminum. These minerals are used in different form as per the availability of the minerals.Step 1 – Quarrying Limestone and a 'cement rock' such as clay or shale are quarried and brought to the cement works. These rocks contain lime (CaCO3), silica (SiO2), alumina (Al2O3) and ferrous oxide (Fe2O3) - the raw materials of cement manufacture. Step 2 - Raw material.

    Ball Mill Mass Balance In Steady State

    Cement is produced by chemically combining calcium carbonates, silica, alumina, iron ore, andsmall amounts of other materials. These ingredients are chemically altered through intense heat to form a compound with binding properties. Raw materials including limestone, chalk and clay will pass through a crusher after they aretreated .Sulphur in raw meal increases SO x emission and causes build-up in preheater. Sulphates needs to balance alkalies in kiln system. Excess sulphates can be calculated as Sulphate Excess= SO 3-0.85 x K 2 O-0.65 x Na 2 O (g 100kg clinker) Cl chlorides can come from raw materials and fuel.
