As most of the material streams in a modern cement plant are dry, emission control is essential to plant operation. Additionally, the plant must monitor the operation of its dust collectors on a regular basis- main dust collectors are also monitored by the Department of Environmental Protection (DEP). While the plant was required to visually ...

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.

4 Quality Control: At the Foundation of Sustainability. Sudeep Sar, FL, explains how the use of supplementary cementitious materials and alternative fuels has made modern quality control and automated sampling & analysis systems a prerequisite for ensuring both process consistency and a lower environmental footprint.
re Cement Process & Quality Control. 1. Mineralogy of Raw Material used for manufacturing of Cement. You need a good deal of reasonably pure limestone (or marble of chalk or othe form of CaCO3); some shale, clay, schist or other material that is mainly composed of compounds of silicon, iron and aluminium.
cement - cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.

The rotary cement kiln process is intrinsically unstable, there are long time delays and large perturbations acting on it. The control problem consists of maintaining a given temperature profile along the kiln plus obtaining good burning conditions.
The cement manufacturing process is a highly energy-intensive process, with many unpredictable disturbances. To manage process, the operators are spending a lot of time, efforts and have to permanently monitor the process very carefully. The goal of the Kiln Control System is to increase the quality as well as efficiency of clinker production.

In this process, the hydrated cement reacts with CO 2 in the air, slowly reversing some of the processes that took place in the kiln when the cement was made (this is the carbonation process; it also causes reinforcement corrosion, see Section 25.3.2). It is estimated that this may reduce the carbon footprint of the cement industry by 3–5%.
