How a Grate Discharge Ball Mill Works. Here I try to explain how ground slurry is discharged from a grate ball mill . 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.
The discharge grate plate of the ball mill directly affects the grinding effect of the ball mill, but the current discharge grate plate is often seriously blocked, which leads to problems such as smaller ventilation area, poor ventilation and over grinding of the ball mill, affecting the normal operation of the ball mill.
where an approximate figure for the constant is 3.5 for rod mills, 4.0 for overflow ball or pebble mills and 4.5 for grate discharge ball or pebble mills. ç is specific gravity of grinding media q is the charge volume in fraction of mill volume nc is the mill speed in fraction of critical speed
