The most used coal mills in cement plants are airswept ball mills and vertical roller mills. At present, most cement plants use coal as the main fuel in the clinker production process. The standard coal consumed by the new dry process for producing 1 ton of cement clinker is usually between 100 kg and 130 kg, and the fuel cost accounts for ...
In the wet process of cement production, raw materials should be ground into raw slurry with a water content of 30% 40%. While in the dry process of cement production, they will be ground into dry powder in cement raw mill. Raw mill in the dry process: cement ball mill, cement vertical mill, Raymond mill, etc.

In recent years vertical roller mill (VRM) has proved to be a popular choice for finished cement grinding due to low power consumption but it is also very sensitive to vibrations and can deteriorate productivity if process optimization is varied slightly.
The plant has two cement production lines which in total produces 5300 t/day cement. The raw materials (lime, silica, and iron ore) enter the circuit through two apron feeders. The raw materials are crushed in a hammer crusher to D 95 80 mm. The raw materials were mixed in a certain proportion and fed into a vertical roller mill (LOESCHE mill).
In the mid1990s, the vertical roller mill (VRM) was introduced to the cement industry to reduce this energy usage. Besides lowering power consumption, VRMs may improve process capacity...
1. Introduction The Indian cement industry have many major players in the league. The top 20 cement companies produces almost 70% of the total installed production capacity in the country. There are 210 large cement plants having total capacity of 410 MT cement production, with 350 small plants account for the rest.
