The profiling of the shell lining plates creates the movement of the ball charge, which causes the grinding of the material. It is therefore essential for effective grinding in the mill and far more than just a wear part. The exact profile shape has to be defined depending on the ball sizes used, the rotation pace and the mill diameter.
When a ballmill fitted with a diaphragm is overfed, the mill fills up to a certain level, then stops crushing and discharges any additional feed back through the feed trunnion. Once overfed, it takes from 30 min. to 2 hr. to free itself. Ballmills, therefore, should be provided with a central opening in the diaphragm connecting with the ...
Ball mills and grinding tools Cement ball mills are typically twochamber mills (Figure 2), where the first chamber has larger media with lifting liners installed, providing the coarse grinding stage, whereas, in the second chamber, medium and fine grinding is carried out with smaller media and classifying liners.
By means of the open lifter diaphragm, the drying chamber integrated into the mill tube is separated from the grinding compartment. The steel grades used can easily withstand the up to 400°C hot gases found in the drying compartment. Construction of the diaphragm in Monobloc® version: supports the mill tube and resists deformation.

Significant coarse particle accumulation did not take place at the end of the mill. The behavior is the same in the second compartments of most of the twocompartment type ball mills. However, the situation is different in the first compartment of twocompartment ball mills due to the intermediate diaphragm slot and grate opening dimensions.

Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 250 microns.; The CenterPeriphery Discharge mill has feed reporting from both ends and the product discharges ...

In the coarse grinding department, the grinding media are sized to crush just the coarsest particles in the mill feed,
Ball mills are usually either of the grate (diaphragm) or overflow type. Ball Mill Components. Ball mills consist of the following components: Inlet crushed ore is fed to the ball mill through the inlet. A scoop ensures the feed to the mill is constant. Discharge reduced feed exits the mill through the discharge. Ball Mill Components

Figure B indicates a mill where a diaphragm or grate is placed before the exit end so that particles greater than the openings of the diaphragm are not discharged but held back for further grinding. Grate discharge mills give less excessive grinding compared to overflow mills and are best suited to grinds to 150250 μm. In Figure C, the discharge opening is at the centre of the mill ...
The ball mill diaphragm is an important component of the ball mill liner. The performance of the ball mill diaphragm not only affects its service life and ball mill operating rate but also has a significant impact on the grinding efficiency of the ball mill. Materials for ball mill diaphragm include high manganese steel, new composite materials ...
