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.

IMPROVED CEMENT QUALITY AND GRINDING EFFICIENCY BY MEANS OF CLOSED MILL CIRCUIT MODELING A Dissertation by GLEB GENNADIEVICH MEJEOUMOV Submitted to the Office of Graduate Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY December 2007 Major Subject: Civil Engineering
Closed circuit grinding system. See the advantages of closed circuit grinding. The method of installing a bowl classifier to overcome the difficulty is shown in Fig. 27. This circuit is usually adopted in modern practice, but with a bowl instead of a straight classifier, if necessary, in the closed circuit of the secondary ball mill.
Compared with an open-circuit cement mill, the output of the cement mill is increased by 40 ~ 100%. Compared with centrifugal type and cyclone type closed-circuit mill, the output can be increased by 15 ~ 40%. The power consumption of the grinding system is reduced by 10 ~ 20%.

A conventional cement grinding circuit is composed of a two compartment tube mill, a mill filter which collects the fine material inside the mill and a dynamic air separator where final product
A 1.5 mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance interms of system availability and output, however power consumption was on higher side. 3.1 System Description Mill Rated capacity 150 t/h OPC at
Reductions in the range of 4-6 kwh/t cement are reported from India, depending upon the product type. In China, for 5000t/d cement production line using a ball mill with closed circuit system, power consumption index is reported to range between 38 ~ 42kWh/t (NDRC, 2008. p.48).

re CLOSE CIRCUIT AND OPEN CIRCUIT. Dear Arman, If you have a cement mill with seprator system and the reject of that seprator is back to your mill its mean it is close circuit. regards, Sheikh. Reply. Page 1 of 1 1.

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. Gypsum is interground with the clinker in order to control the setting properties of the cement.
Cement setting times; Cement water demand (at a constant workability) * SSA is the specific surface area (m 2 /kg) of the finished cement (final product). CLOSED CIRCUIT MILL ‑ ANSWER. i) Lower mill exit surface area means lower fineness in the mill itself and so less tendency for agglomeration, coating, over grinding, cushioning etc.
