Grate type ball mill . overflow vs grate discharge ball or mill why retrofit types of ball mills in the case of ball mills these are the overflow type semigrate or intermediate pulp level discharge and the true grate discharge a general statement can be made that the closer the discharge is to the periphery of the shell the quicker the material.How a grate discharge ball mill works. aug 13, 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 discharged metso/ discharge.
It has been widely accepted to go for grate discharge ball milling when a coarse product is preferred or to avoid production of extreme fines, but overflow discharge mills are preferred for their simplicity of design and production of finer product. in grate discharge mills the product is discharged primarily due to hydraulic gradient from the feed end to discharge.Jun 23, the grate discharge arrangement removes this slurry pooling effect almost completely. 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.
Jun 24, 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.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.
