closed circuit clinker ball mill

Cement ball mill is a kind of ball mill grinder. It is mostly used for grinding cement clinker and raw materials in cement plants and is also suitable for grinding various ores and other grindable materials. Cement ball mills can be applied in the open-circuit grinding system and the closed-circuit grinding system.

The cement clinker grinding plant or cement grinding station acts as an individual production line in the last period of the cement production process. In the finished product period, the cement clinker is ground by adding moderate mixing materials and then forms the finished cement. There are three procedures of the cement grinding plant: raw material preparation, clinker burning …

3.1.1. Description of Mill Employed. Industrial closed-circuit tube (or ball) mill schematically presented in Figure 1 was used for cement production. The clinker initially passes through a double-deck screen, where all particles larger than 10 mm are sent to a precrusher.

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.

Cement ball mill is a kind of cement grinding equipment commonly used in cement plants. It is mainly used for grinding materials in cement clinker section.

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.

In this unit, the input materials (Clinker, Gypsum, Pozzolana, and Limestone additive) are proportioned and ground in Cement mill (one Closed circuit ball mill in line 1 and two Roller press+closed circuit ball mill in line 2) based on the type of cement to be produced keeping the quality of cement equal or above the required standard.

Closed-circuit grinding is necessary when large mills are required to produce finely ground cements and also in situations where there is a significant difference in the hardness of the Portland cement clinker and any secondary material incorporated into the cement.

In the closed-circuit system, the mill product is classified in a separator in a fine fraction that is then taken to the next step and a thick fraction that is returned to the mill for subsequent milling.
