Horizontal Grinding Mill Overflow Type, Grate-discharge ...

The grate-discharge type of Ball Mill has a grate at the outlet of the shell and causes less excessive grinding, compared to the overflow type. Therefore, generally, it is best suited to grind materials up to the particle sizes ranging from 60 to 100 mesh.


Trunnion overflow mill - Big Chemical Encyclopedia

Tumbling mills are cylindrical size reduction devices and are essentially lined drums supported by hollow trunnions at each end. The units are manufactured with overflow, grate, or peripheral, discharge arrangements (Figure 6.16). [Pg.170] See other pages where Trunnion overflow mill is mentioned: [Pg.192] [Pg.192] [Pg.1612] [Pg.208] [Pg.1857 ...


TECHNICAL NOTES 8 GRINDING R. P. King - …

of overflow-discharge mills but not to the same extent in grate-discharge mills. This pool is situated more or less symmetrically with respect to the axis of the mill and therefore does not draw significant power. Austin recommends K = 10.6 for overflow semi-autogenous mills. A value of K = 9.32 makes Austin's formula agree with Morrell's data

Converting a ball mill from overflow to grate discharge ...

If a mill has available power, conversion of the discharge arrangement from overflow to grate can be beneficial in allowing increased throughput or a finer product size. Conversely, if the mill does not have available power then it is still possible to install a grate discharge and to draw the same power by using a lower ball charge.


Slurry flow in mills: grate-only discharge mechanism (Part ...

Typically in wet overflow grinding mills the product is allowed to exit the mill by overflowing the discharge trunnion. The driving force for flow of slurry from the feed to discharge end of the mill is the flow gradient due to the discharge trunnion being larger than the feed trunnion. However, grate discharge mills have a more complex mechanism.
