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 possible to overflow out of the discharge

  • The effect of grate design on the behaviour of grate

    01.09.1986· Mori et al. (1967) measured hold-up of dry solids in a pilot grate-discharge mill and found that the %open area in the grate had very little effect on hold-up (presumably because the mill was a relatively long one, with length/diameter ratio of 3.6, so that the end-effect provided by the grate was small). Gupta et al. (1981, 1982) have reported data measured on various ores in a 0.4 m 0.4 m pilot
