The cement clinker grinding circuit reduces the feed from 80% passing size between 10 and 20 mm to passing 90 μm. The size reduction takes place in a two compartment tube mill; the first compartment of the mill is shorter than the second compartment.
(3) favorable ventilation inside the ball mill. For cement ball mill, ventilation is needed to dissipate heat so as to cool the cement. Meanwhile, the fine powder can be moved out in time and quickly to reduce the effect of uneven ventilation must be eliminated as far as possible by the compartment separation device.

Two 12 x 36 ft. twocompartment ball mills are employed in the existing plant, whereas a Polysius twocompartment ball mill with SEPOL 330/0 separator driven by 2 x 5700 hp motors will be used in the new facilities. The capacity of the cement silo in the existing plant .
applications of the vertical roller mill for cement grinding are less prevalent. The twocompartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding installations although the vertical roller mill now has emerged as a viable alternative
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 is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
An industrial test work was performed to analyse the effect of applying a lower ball load and a finer ball size distribution in the second compartment of a KHD Humboldt Wedag ® ball mill on grinding and classification performance of a hybrid high pressure grinding roll (HPGR)/multicompartment ball mill cement grinding circuit. Mass balance of the circuit was done by JKSimMet Steady State ...
