11.6 Portland Cement Manufacturing

1971-8-17  The initial production step in portland cement manufacturing is raw materials acquisition.Calcium, the element of highest concentration in portland cement, is obtained from a variety ofcalcareous raw materials, including limestone, chalk, marl, sea shells, aragonite, and an impurelimestone known as "natural cement rock". Typically, these raw materials are obtained from open-facequarries, but underground mines or dredging operations are also used. Raw materials vary fromfacility to facility. Some quarries produce relatively pure limestone

Modeling and Optimization of Cement Raw Materials

The cement raw material blending process is an important link because the blending process will affect the cement clinker quality and critical cement craft parameters, thus the blending process finally affects the cement quality. Figure 1 demonstrates cement raw material blending process and its control system. Cement original materials are usually the limestone, steel slag, shale, sandstone, clay, and correct material.

Chapter 4 MATERIAL BALANCES AND APPLICATIONS

2008-3-3  A material balance is an accounting for material. Thus, material balances are often compared to the balancing of current accounts. They are used in industry to calculate mass flow rates of different streams entering or leaving chemical or physical processes. 4.2. The General Balance Equation

Modeling and Optimization of Cement Raw Materials

Cement raw material and cement clinkers mainly contain four oxides: calcium oxide or lime (CaO), silica (SiO 2), alumina (Al 2 O 3), and iron oxide (Fe 2 O 3). The cement clinkers quality is evaluated by the above four oxides. Hence, ingredient ratio of cement raw material will affect the quality and property of cement clinker significantly.
