An environmentally conscious business leadership has placed India amongst the most energy and resource efficient manufacturers of cement in the world. The energy efficiency within the Cement Industry is measured as a combination of two factors – thermal specific energy consumption and electrical specific energy consumption.
Grinding systems in cement production make up approximately 85 to 90 percent of total plant electrical energy consumption. As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions, they give cement plant owners a great opportunity to maximise productivity and minimise operating costs.
The cement industry is the main supplier of raw materials for the production of concrete and reinforced concrete. For grinding cement, two types of mills are used - ball and roller.
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.

In the study the advantages of vertical roller mill are discussed over ball mills. VRM construction, its process and parameters which affects the performance and productivity of vertical roller mill are discussed. ... Dry and semi-wet processes are more energy-efficient. The wet process requires 0.28 tons of coal and 110 kWh to produce …
In conclusion, the application of vertical roller mill technology in the cement industry has revolutionized the way cement is produced. VRMs are more energy-efficient, eco-friendly, and produce a more consistent product compared to traditional grinding mills. They are also more suitable for use in urban areas due to their lower noise level.

An inefficient ball mill is a major expense and could even cost you product quality. The best ball mills enable you to achieve the desired fineness quickly and efficiently, with minimum energy expenditure and low maintenance. With more than 4000 references worldwide, the FL ball mill is proven to do just that.
A cement vertical roller mill (VRM) is a type of grinding equipment commonly used in cement plants for raw material grinding and cement grinding. It is an energy-efficient alternative to traditional ball mills, as it utilizes rollers to grind and crush the materials between a rotating grinding table and a set of rollers mounted on a vertical axis.
