By absorbing the advanced technology from the world, Shanghai Dingbo researched and designed ball mill. is widely used in mineral processing,
building materials and chemical industries. ball mill machine grinds material by rotating a cylinder with steel grinding balls, causing the balls to
fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the
diameter of the ball mill machine. The larger the diameter is, the slower the rotation is. If the peripheral speed of the ball grinding mill is too great,
it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill
Ball Mill 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.
Ball Mill features and Benefits :
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.
