How Cement Is Made
Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients Common materials used to manufacture cement include limestone, shells, and chalk or marl combined within bags to the market Cement clinker and finished cement are traded internationally Cement manufacture is a very energy intensive process and results in the production of large amounts of carbon dioxide (CO 2) The carbon dioxide is chiefly produced when the calcareous raw material is calcined to produce calcium oxide Generally around 05 tonnesCEMENT RAW MATERIALS
Ball Mill & Roller Press for Cement Grinding Process
The combined grinding system of roller press and ball mill With the invention of Vtype separator, the combined grinding system composed of roller press and ball mill has been developed to further reduce the energy consumption of the cement grinding process In this system, the ground materials from the roller press is first processed by thecement mill operations in four ways: • More consistent quality (grade) The continual monitoring of the mill loading and the adjustment of the feed and separator results in reduced variations in cement grade This has the added benefit of a more consistent product quality The control strategy is designed to respond to disturbances in theIndustrial : Optimization for the Cement Industry ABB
