Analysis of material flow and consumption in cement production process
The LN cement plant, located in the south-west of Shandong Province, was considered as a case study for the mass flow and balance analysis. This cement plant operates on a dry process line with a five-stage suspension pre-heater and an inline pre-calciner. The kiln is 4 m in diameter and 60 m in length.

Cement
There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement).

Cement Production Process | Cement Manufacturing
There are three steps of the high-temperature system: Drying or preheating, calcining, and sintering. The calcining is the core part of the clinker production; the raw meal is weighed and sent into preheater and cement kiln to process clinker. Grate cooler helps to cooler clinker, the cooled clinker is sent to the cement silo for storage.

How Cement Is Made
The heated air from the coolers is returned to the kilns, a process that saves fuel and increases burning efficiency. After the clinker is cooled, cement plants grind it and mix it with small amounts of gypsum and limestone. Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix ...
