Classification Code (SCC) for portland cement plants with wet process kilns is 3-05-006, and the six-digit SCC for plants with dry process kilns is 3-05-007. Portland cement accounts for 95 percent of the hydraulic cement production in the United States. The balance of domestic cement production is primarily masonry cement. Both of these

Simple material balance problems involving only a few variables can still be solved manually. However, it is general ly more efficient to use a computer program such as a spread-sheet. Both approaches are discussed in Section VII. In order to achieve high levels of mass and energy utilization efficiency, most processes involve the use of recycle.

may be chosen such as mass, or concentrations which can be by weight or can be molar if reac-tions are important. 4.3.1 Total mass and composition Material balances can be based on total mass, mass of dry solids, or mass of particular compo-nents, for example protein. Example: Constituent balance

anhydrite) in a cement mill to control the properties of the cement. Combinations of milling techniques including ball mills, roller mills, or roller presses are often applied to ground clinker with additives in cement mill. The finished cement is being transferred via bucket elevators and conveyors to silo for storage [9].

According to the investigation, there is a balance between input and output material in the cement grinding system; the relevant data and equations to evaluate the different component of this system mass balance are listed in Table 6. In the cement plant, 3.41 kg of materials is required to produce a kg of cement in the final stage.

Heat and mass balance is a document produced by process design engineers while designing a process plant. Sometimes heat and mass balance is not a separate document but appears alongside the Process Flow Diagram (PFD). A heat and mass balance sheet represents every process stream on the corresponding PFD in terms of the process conditions.
