In this unit, the proportioned raw materials are being ground to the size of (10% residual on 90 m sieve) by closed circuit ball mill in line 1 and Vertical Roller Mill (VRM) in Line 2. While grinding; the raw materials are being dried from 4% moisture content to lt;1% using the excess hot gas emitted from pyrporocessing system.
cement industry the ball mill was really an epochmaking breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw
Ball mills and vertical roller mills are used for many grinding applications in cement production: raw meal grinding, coal and pet coke, and finish cement grinding. Improving the competences of the team plays a key role in the optimal utilisation of the grinding installation in your cement plant.
Cement raw material has been almost exclusively ground in roller mills (vertical airswept grinding mills) since the second half of the 20th century. Loesche was and is the pioneer of this technology. Hundreds of Loesche mills have been used in the cement industry across the world to the present day. They operate with two, three, four and six
