The final manufacturing stage at a cement plant is the grinding of cement clinker from the kiln, mixed with 4-5% gypsum and possible additives, into the final product, cement . In a modern cement plant the total consumption of electrical energy is about 100 kWh/t . The cement grinding process accounts for approx. 40% if this energy consumption.
Setting up a cement plant is both time and capital intensive; it could take anywhere between five to seven years from concept to commissioning and an investment of around to Rs 1,800-2,000 crore for a typical integrated plant of 3 million tpa cement capacity. Size of a cement plant could vary from 0.2 million tpa to 5.0 million tpa.

A major part of thermal energy relates to the Pyroprocessing system. For a 1 million mt/year clinker production, savings of 10 kcal/kg-cl would result in yearly savings of approximately $185,000, assuming a heat value of 6500 kcal/kg and coal price of USD120/t. ×. Savings inUSD = 1, 000,000 10 × 120 ≈ USD 185,000 6,500.

Cement grinding with our highly efficient ball mill. 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 ...
Cement is a "low value, high volume" product. As of this writing in May 2023, a 50 kg bag of cement costs roughly ₹400. Compare that with a bag of grains or cloth or cosmetics or gold. Transporting a unit of any of these items from one point to another will surely bring higher revenues than transporting the same unit of cement.
Check the level of the grinder discs. The goal is to have surface contact. Hold the machine in place for several seconds, then look at the pattern it leaves. You should see a full circle ground into the surface. If you see a half-circle, follow the directions for adjusting the level of your grinder. If you're working over a large area ...

By. admin. Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started …
