A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
In this study, separator rejects of a closed circuit cement tube milling were dry ground in a 10-l pilot scale vertical stirred mill. Tests were done as open and closed circuit. The results were evaluated by size distributions, Blaine surface area of the products and the specific energy consumed during the tests.
a comparative analysis of the recent cement grinding METU. Feb 11, 2011 operated to improve the process. In addition to the closed-circuit, two- compartment ball mills known for decades, combined grinding systems with closed-circuit high pressure grinding rolls and downstream closed-circuit ball mills have been used for nearly 20 years.

Closed-circuit grinding. Closed-circuit grinding is a size-reduction process in which the ground material is removed either by screening or by a classifier and the oversize is returned by integral classification to the mill for further processing.
Grinding systems are either 'open circuit' or 'closed circuit.' In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding.
For raw grinding with relatively dry raw materials, the combination of the roller press and V separator is a viable alternative with far lower mill fan power. Cement grinding. For cement grinding, the technology development away from ball mills has taken a different route.
Cement grinding. The clinker from the pyro-processing area is ground in ball mills or roll press + Ball mill combination or vertical roller mills to form cement. Commonly used separators are in closed circuit grinding are: O –sepa, Sepol and Sepax separators to achieve a finish cement fineness of 3000 – 4000 Blaine surface (cm2/gm).

Analysis of the efficiency of the grinding process in closed circuit ball . Ball mills for fine grinding cement clinker and additives are Technological system of grinding (TSG) in a closed circuit on the basis of the ball mill For this grinding unit this parameter is 1.08·104 kWhpm2.
Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating load ...

All these calculators are reliable, but Users need a certain experience to implement results of these calculators . Sizing equipments and mill's optimization are the job of material suppliers and experienced engineering offices.
Closed-circuit systems are relatively dynamic and complex, but the closed-circuit grinding method is fully applicable to open-circuit grinding. As we all know, there are many factors affecting the quality of mill production, including three major aspects, one is the nature of materials, there are grinding grain size, easy to grind, finished ...
Closed circuit ball mill with two compartments for coarse and fine grinding and a drying compartment with lifters are generally found in cement plants for raw material grinding. Compartments (filled with grinding media) are divided by a double diaphragm with flow control to utilize maximum mill length for effective grinding.
Finish grinding with a roller press operating in closed circuit with disagglomerator and separator. Finish grinding with vertical roller mill. Selection Criteria for the Cement Grinding System . Availability of grinding capacity to be required; Physical characteristics of the material to be ground
Operation and Elements of a Closed Circuit Ball Mill System. Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.
