Space needed for vertical mill is much less than a closed circuit ball mill of same capacity. As separator is integral part of the mill itself, the number of auxiliary equipments are less. Total power consumption for grinding circuit as a whole is also less by about 30% compared to closed circuit ball mill in spite of higher fan power.

Mill ventilation is important for cooling the mill, removing moisture and improving mill efficiency. Typically, a velocity across the media of 1m/s is a good target. The challenge is to measure it. Cement producers are required to measure and report to government agencies about the air that flows up the cement mill stack.
For open circuit cement milling, and older generation closed circuit milling, water Is usually injected into the mill for cooling and this is usually sufficient to condition the dust for effective precipitation. For effective operation the water dewpoint temperature of the air at the inlet to the precipitator must be in excess of 450C.

Mill capacity decreases as the demand in fineness increases. Mill Air flow : Normally Flow across Mill is kept as 2 to 3.0 m/sec for raw materials grinding 1 to 1.5 m/sec for close circuit of cement grinding 1 to 1.2 m/sec for open circuit of cement grinding
According to statistics released by the Statistical Institute of Mexico (INEGI) in 2019, the annual average production of gray cement was 3.32 million tons, while the previous year it was 3.55, thus registering a decrease of 6.92%. This means that currently the Mexican cement industry is working at 60% of its installed capacity.
The maximum fineness attainable by open circuit stirred mill tests is 6200 cm 2 /g. • During the open circuit tests, specific energies excessively increases beyond Blaine values of 4500 cm 2 /g which corresponds to a specific energy consumption of 60 kW h/t. Beyond this point, further grinding can be obtained for the speeds above …

What Is A Cement Ball Mill. The cement ball mill is a kind of cement grinding mill.It is mainly used for grinding the clinker and raw materials of the cement plant, and also for grinding various ores in metallurgical, chemical, and electric power enterprises.It has the characteristics of strong adaptability to materials, continuous production, a large …
circuit product and is sent to the storage and dispatch silos, while the coarse material returns back to the cement mill to be ground again. Fig. 1 shows the grinding circuit layout of the industrial cement plant under study. The elements identified in the cement grinding circuit are: G20 is the ball mill; G24 is the dust collector of the ball ...
The vertical roller mill (VRM) is a type of grinding machine for raw material processing and cement grinding in the cement manufacturing process.In recent years, the VRM cement mill has been equipped in more and more cement plants around the world because of its features like high energy efficiency, low pollutant generation, small floor area, etc.. The …
