In the traditional cement factory, it is im-possible to estimate cement strength with any certainty until its 1-day and 28-day strengths are measured through physical tests. Producers tend to compensate by us-ing costly, high-quality limestone and addi-tives to ensure a high-performing product. Alternatively, they may mill the product

Reducing energy consumption of a raw mill in cement industry
In this study, the first and second law analysis of a raw mill is performed and certain measures are implemented in an existing raw mill in a cement factory in order to reduce the amount of energy consumption in grinding process. The first and second law efficiencies of the raw mill are determined to be 61.5% and 16.4%, respectively.
Thus, I can put forward all my technical, personal & management skills for enhancing the company's goals and my professional growth. I work in a Cement factory as a mechanical engineer. I'm responsible for the Raw mill and Kiln which is the heart of the cement factory.
This long, rotating cylindrical kiln will add motion and authenticity to your cement factory complex. Valley Cement is a great destination for Walthers ready-to-run covered hoppers and open-top coal and aggregate hoppers. The complex as shown measures 40-1/2 x 23-1/4 x 11.5" 102.8 x 59 x 29.2cm
The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all man-made CO 2 emissions. Physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity.
