The grate ball mill is usually used in the first segment of the two stages, orplace of discharging the rough ore.
The grate ball mill is roughly composed of the cylinder, cylinder liner,biggear ring, discharging grate,and ore feeding device. Except there is adischarging grate plate installed at the discharging end, all the other issimilar with the overflow ball mill. The grate ball mill discharging cover headand grate plate have the structure as the drawing: grate liner, bearing innercover, hollow shaft, dustpan liner, central liner, rib and wedge block.
In the head cover of the hollow shaft of the discharging end, it has bearinginner cover and discharging grate installed and the later is made from centralliner, grate liner and dustpan liner etc. There are eight radial rib casted onthe inner wall of the head cover, which divide the head cover into 8 fan rooms.There installed the dustpan liner inside each fan shape room, with the boltfixed on the end cover. Finally the grate plate are installed on each fan roomshaped by the dustpan liner. The grate liner has two kinds of structure: one isthe group formed by two pcs, pressed by the wedge block, which get fixedtightly on head cover with the bolt getting through the rib. The central partare supported by the central liner to prevent them from declining and droppingoff. The other kind is get two pcs into one block, fixing with bolt directly.The central liner is star shape, formed by two block, tightened on the rib withthe bolt.
The hole on the grate liner is arranged at inclining direction. The width ofthe hole is getting bigger gradually to the discharging end, which can preventthe slurry from regorging and rough granularity from blocking. The slurry flowinto the fan shape room through the hole on the grate plate from the lower partof the discharging end, and get passed up to the upper part along the cylinderrotating and discharged off the hole path. The hollow shaft neck has thegrinding proof inner cover, with one end made of trumpet shape blade to leadthe slurry to flow out of the mill. As the slurry in this kind of mill isdischarged through the grate plate, it is called the grate ball mill.
