The SAG mill is fitted with a 20 MW gearless drive motor with bi-directional rotational capacity.

Cement grinding operation may be performed in one of the following mill setups. Ball and tube mills. Vertical Roller Mills (VRM). Roller press with Ball mill. Ball Mill. Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical ...Optimization of Cement Grinding Operation in Ball . 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.

Closed-circuit Grinding System. The closed-circuit grinding system of the ball mill is shown as follows: materials mixed in a certain proportion will firstly enter the cement ball mill for grinding and then be sent to the powder concentrator by bucket elevator. The powder concentrator divides the materials into coarse and fine materials.Open and closed circuit dry grinding of cement mill .

Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.The grinding circuit operator must ensure that the ball mill runs properly loaded and gives the correct ore grind. A major practical indication of mill loading is the sound made by the mill. A properly loaded mill will have a deep rhythmic roar, while an under loaded mill will have a metallic rattling type noise and an overloaded mill will be quite silent.
