    13/8/2015· How a Grate Discharge Ball Mill Works Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG) How it works is, the slurry flows across the grate as it would a screen panel On the other side of the grate/screens are veins like a pump impeller As the mill turns/rotates the slurry is “pumped” out and discharged24/6/2015· 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 noOverflow VS Grate Discharge Ball or Mill Why Retrofit19/8/2021· Grate ball mill discharge side cover 1Grate liner 2Bearing inner sleeve 3Quill shaft 4Skipshape liner 5Central liner 6Steel bars 7Drill key Different of feeding device of grate ball mill 1 The feeders of ball mill are: drum type, worm type and combined type, and their structures are shown as (a), (b) and (c) in the figure Drum type feeder is made of pig ironGrate discharge ball mill | Henan Deya Machinery Co, Ltd

  • Converting a ball mill from overflow to grate discharge

    23/6/2020· Estimates of the increases in power draw possible with grate discharge ball mills range from 10% to 20%, according to mill size and other operating parameters The figures from pilot tests and some operating sites are even higher, up to 25% more power draw If a mill has available power, conversion of the discharge arrangement from overflow to grate can beThe grate discharge ball mill is also called grate ball mill It is often used in the first stage of twostage grinding to dry or wet grind various ores and other grindable materials Compared with overflow ball mill, grate ball mill is a type of ball mill grinder that can realize forced ore discharging by grid lining plate and fanshaped chamber Besides, it has a larger capacity,Grate Discharge Ball Mill Efficient Grate Ball MillA set of experimental test work has been carried out in a continuous pilot ball mill of 041m X 056 m (diameter X length) at different mill speeds, percent solids and discharge mechanism The results of study on material flow through a grate discharge tumbling mill verses an overflow tumbling mill are presented to emphasize the effect of discharge flow mechanism TheOverflow Versus Grate Discharge Ball Mills: An
