Large Discharge Opening Mineral Ore Mining Ball Mill / Ball Milling Equipment

Newly designed mining ball mill used in the mineral ore procesing plant

Grid ball mill description:

Discharging part of the grid ball mill is composed of the cover with hollow shaft neck, grid lining, wedge

block, center liner, shaft internal bushing and other parts.

Materials are put in cylinder through the feed opening and then thoroughly grinded, because the falling

course of iron balls and ores can produce huge falling impact and autogenous grinding. The continuous

feeding of ores can create considerable pressure to make ores move from feed opening toward

discharge opening. Finally, acceptable particles are discharged from the discharge opening. The

discharge opening is equipped with a discharge grate, and the ore pulp horizon of discharge opening is

low. These two factors prevent ores from being overly grinded, and iron balls from being dismissed.  

Application:

Grid ball mill is used for grinding nearly all kinds of ores and other related materials, which is widely

used in beneficiation, chemical industry, building and national economic sectors.

Features:

1) The transmission machinery of grate ball mill substitutes large-scale double row self-aligning roller

bearing for sliding bearing. It is easy to start and saves energy up to 20-30%

2) Adopt groove-type circular lining plate which is instrumental in increasing contact areas of iron balls

and ores, and enhances grinding action and ore lifting capacity and decreases energy consumption.

3) Adopt overall frame, which makes it easy for construction and installation.

4) Large discharge opening, high capacity.

5) Equipped with oil-mist lubrication device which guarantees smooth operation of gears.
