We recently converted a grate discharge type ball mill size 57x86m to an overflow type before conversion the ball level was 26 and we were able to obtain a grind of 90 passing 75mic at a throughput of 350th after conversion its a nightmare to obtain 90 passing 75mic at the same thro
Overflow ball mill is a kind of ball grinding mill which works in wet water state it belongs to a type of wet ball mill and is a very common grinding equipment in the concentrator ball grinding mills are classified according to the discharge methods and can be divided into overflow ball mill and grate ball mill
Principle of the overflow ball mill the main component is a cylinder with diameter and length at a reasonable proportion driven by the transmission device the cylinder rotates with the materials fed from the cylinder inlet and crushed by the falling impacts and autogenous grinding of the steel balls and ores in
For overflow ball mills the charge should not exceed 45 of the mill volume for grate discharge mills the charge should occupy about 50 of the mill volume bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge he and the radius of the mill r ie
Compared with grid type ball mill overflow type ball mill can grind materials finer even though its grinding time is usually longer so it can make finer particle products hence the grid type ball mill is mainly used for primary stage of grinding while overflow type ball mill is mainly used for the secondary grinding

Jun 23 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
In general the productivity of the grid type of ball mill is 1025 higher than that of the overflow type ball mill and the power consumed is 1020 higher than that of the overflow type ball mill the grid type ball mill consumes a large amount of power but its production efficiency is high
Overflow type ball mill overflow type ball mill the overflow ball mill has relatively simple structurethe advantage of no grate fence high fineness in grinding and
The overflow type of ball mill is designed to overflow and discharge materials from the trunnion on the outlet side by combining it with a mechanical classifier or wetprocessing cyclone you are able to extensively use this type for grinding in closed circuit or for special applications such as regrinding in
