Cement production is one of the most energy‐intensive manufacturing industries, and the milling circuit of cement plants consumes around 4% of a year's global electrical energy production.
MP Birla Group has two cement plants at Chanderia (Rajasthan) – Birla Cement Works (BCW) and Chanderia Cement Works (CCW). Here is a case study on the various initiatives taken to reduce thermal and electrical energy consumption at for both the lines of CCW. Cement clinker is manufactured primarily from limestone, clay, sand …
The specific energy consumption and the cement setting times increased in the order of combined grinding, HPRM grinding, and horizontal roller mill grinding.
Electricity consumption is a major energy efficiency indicator in cement raw materials grinding system. Advance prediction of electricity consumption provides the basis for cement production scheduling and achieves the energy saving.
More than 60% of total cement plant electrical energy consumption is utilised in grinding systems. Higher AFR utilisation and new cement types also make it necessary to adjust and adapt cement mills – both internal configuration as well as operation.
A considerable share of industrial energy and resource consumption can be attributed to machine tools in general and grinding machines in particular. Grinding is an essential technology used for finishing operations of many precision components, especially such made of hard and brittle materials.

Semantic Scholar extracted view of "SA-LSTMs: A new advance prediction method of energy consumption in cement raw materials grinding system" by Gang Liu et al.
As grinding accounts for a sizeable share in a cement plant's power consumption, optimisation of grinding equipment such as ball mills can provide significant cost and CO emission beneits to the cement producer.
Electrical generation construction can be a very cement intensive application. As the technologies vary, so can the amount of cement used by type. To normalize this information, PCA estimated cement consumption by electrical energy source on a per megawatt (MW) basis. Based on this metric, wind energy is the most cement intensive …
Cement is an energy-intensive industry, but currently, electricity accounts for circa 12% within the energy mix, while the rest is various fuels. Total electricity consumption in a dry process is split into equal parts between raw material preparation and clinker production (25% each), then 43% for cement grinding and the remaining for raw material …
