filling in the mill and not related to total mill filling. Discharge through an individual opening on the grate is driven by the factors of ore filling, radial position and the size of the aperture. The results indicate that 1.18 mm is approximately the size below which particles
The ball mill discharge end liner originally uses 12Mn cast steel, while following problems are found (1)It is difficult to repair the liner of high hardness and cast steel with low precision. During installation, a gap is formed between the mill end cover, while the material will wash out the mill end cover and leak the slurry due to the mismatch.
Abstract The results of a detailed study on material flow through a grate-discharge (open-end) ball mill versus an overflow-discharge (constricted-end) ball mill are presented to emphasize the effect of discharge-end design on mill transport characteristics. The effect of feed rate to the mill, mill rotational speed and ball load on the residence time distribution of the flow regime, the ...

adjustable discharge slots. Activate the markers for further information. Working principle. Fed into the mill through one or both bearing trunnions, the material is ground by impact and friction from the balls. The ground product is discharged from the mill through discharge slots provided in the mill tube, through a discharge wall or through the end trunnion.
Milling Slots End mills are designed to cut square slots. They will produce a slot to within two onethouhs of an inch in one pass. If greater accuracy is required use an end mill a little smaller than the desired slot. Measure the slot produced and open it to the desired dimension with a second pass. ...
