Repair Ball Mill Discharge Trunnion Crack - 911 Metallurgist

30/12/2017  There was a continual increase in ball mill lubrication oil consumption. However, visual inspections could not confirm the presence of a trunnion oil seal leak. By the end of month it was assumed that the only possible place for this leak was at the outboard discharge trunnion seal so that oil was leaking into the slurry discharge pump. A maintenance schedule was developed to replace the discharge trunnion deals. When the discharge

Mill Trunnion Liner - 911 Metallurgist

28/07/2015  BALL MILL HEADS AND TRUNNIONS. Ball mill feed and discharge heads are detachable, cast of Meehanite metal of ample thickness, either of GA or GC, depending on the size of mill and with consideration to bending stresses. These heads are generally ribbed for extra strength and stiffness. Such ribs terminate near the center of the head in a trunnion

Overflow VS Grate Discharge Ball or Mill - Why Retrofit

24/06/2015  The discharge end of the Grate Discharge Ball Mill has at least ten times the discharge opening area, through the grate slots, compared to the common trunnion overflow type mill. The discharge grates are designed to run clean and free of any blinding or choking. The pulp level in the mill may be varied by merely changing the pulp dilution. There is no complicated mechanical arrangement to compensate for pulp level changes. The side clamp bars and center discharge

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

23/06/2020  Converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end. The grate holds the balls inside the mill but allows the slurry to pass through, and it is then pumped out of the mill by the pulp lifters. This is different to an overflow mill which holds the slurry and balls inside until the slurry builds up to a level at which it is ...
