A ball mill, a horizontal type and tubular running, has two warehouses. A ball mill runs along the outside gear. Materials spirally and evenly enter the first warehouse along the input hollow axis by input devices. In the warehouse, there is a ladder scale board or ripple scale board. Steel balls of different specifications are installed in the scale board of the Ball milling machine. When the barrel body rotates, centrifugal force is produced. At the same time, the steel balls are carried to some height and then fall to grind and strike the material. After being grinded coarsely in the first warehouse, the material then enters into the second warehouse of the Ball milling machine for regrinding. In the end, the powder produced by the Ball milling machine is discharged by output material board.
Following is the Ball Mill technology update introduction: Previously, the feeding of the Ball Mill Machine units the spoon head with the feeder. Due to the clumsy spoon head, the self-weight, the big eccentricity, and the friction and impact with the deposition ore sand when coping down, the ball mill emerges periodic eccentricity load and impact load. Thus the electric motor of the ball mill operates under the varying load situation which increases the capacity and makes the current fluctuates substantially in the variable motion of half cycle speeding up, half cycle slowing down. The periodic eccentric load and impact load have much effect on main bearing attrition, the stress of the barrel attachment bolt, the mesh of the gear wheel and the pinion, and the heat emitting of the electric motor and shorten the ball mill service life.
The adoption of the drum type feeder can solve the previous problem. Meanwhile the innovation should be made to sand return system of the grader, such as lengthen the grader cell body, adjust the established angle, alter the distance between the ball mill and the grader, add the automatic sand return mechanism on the top of the grader so that the ore is discharged from the top of the grader, by the sand return sliuce, the attitude difference automatic flow and the crude ore sluice, enters into the feeder. The updated ball mill machine is of obvious energy efficiency as well as better Ball Mill Equipment reliability and maintainability.
The ore grinding system in China mostly adopts spiral grader. As it is of larger floor area, low stage efficiency (generally 40%), huge maintenance quantity, and high maintenance cost, the hydraulic power is adopted in the large-scale mining equipment.
