The grates are made of a highly ductile and wearresistant heattreated alloy steel, while the lining plates facing the fine ... 18,000 hours for the grates and 36,000 hours for the plates, when producing ordinary Portland cement from clinker and gypsum. The lifters are radially and individually adjustable, making it
Ball Mill Sole Plate. This crown should be between .002″ and . 003″, per foot of length of sole plate. For example, if the sole plate is about 8′ long, the crown should be between .016″ and .024″. Ball Mill Sole Plate. After all shimming is completed, the sole plate and bases should be grouted in position.
The model structure for the onechamber or multichamber cement ball mills have been subject of various researchers. Benzer et al. [21] developed model for open circuit twochamber cement ball mill. In their structure, the first and second chamber of the ball mill as well as the intermediate diaphragm were all model fitted hence calibrated with ...

mill for cement The mill shell is divided by a diaphragm. Coarse grinding using big balls of up to 100 mm in diameter takes place in the first com partment. The peripheral wear lining is designed as a lifting or activator plate lining which, with the large balls, achieves a high energy input for comminution. The transfer diaphragm allows
Photographs of a intermediate diaphragm in a twocompartment ball mill and a discharge diaphragm in a threecompartment ball mill which have slots are shown in Fig. 9 ... typical discharge rate function which was defined for semiautogenous mill was found to change in the investigated cement ball mills due to a series of factors such as coarse ...
The discharge diaphragm allows the ground material to pass, but retains the grinding balls in the grinding chamber. Christian Pfeiffer adjusts the diaphragm individually to the existing grinding plant, fixing it either on the discharge mill head or floating on the mill shell.
The first compartment was modeled as two ball mills in series, diaphragm between the first and second compartments was represented as a screen and the second compartment is represented as one ball mill. Information given in the flowsheet is solids throughput (t/h), 80% passing size and % passing mm. Download : Download fullsize image; Fig. 6.

Ball mills for finish grinding cement usually consist of two compartments. An intermediate diaphragm separates both compartments from each other. The 1. compartment is filled with coarser balls and lifting liners and is supposed to pre grind coarser particles. The 2. compartment is the fine grinding chamber and is equipped with a finer ball ...
