Ball mill and steel ball correct use of what is
The newly installed ball mill has a running-in process, in the process of running-in, the first addition of steel ball amount, accounting for the ball ball 80% of the maximum capacity, steel ball added by the proportion of ball ball size (Φ120 mm, Φ100 mm, Φ80 mm, Φ60 mm, Φ40 mm) size to add. Different ball mill models with different amount of ball. For example MQG1500 × 3000 ball mill the maximum amount of 9.5-10 tons of ball. The first addition of steel ball ball (120 mm and 100 mm) accounted for 30% -40%, 80% of the ball accounted for 40% -30%, pellets (60 and 40 mm) accounted for 30%.
Why ball mill ball in the process of grinding ball mill only added 80%, because the ball mill installed, the size of the ball gear needs to be engaged, the processing capacity is also gradually increased until the ball mill normal two or three days of continuous operation, picking up the size of gear meshing situation , Until everything is normal, open the ball mill manhole cover for the second time to add the remaining 20% steel ball.
Note: The addition of small steel ball is only the first ball plus use. Because, ball mill normal operation steel ball and steel ball, steel ball and ore, steel ball and ball mill liner generated between the reasonable friction, will wear increased, so that the small ball mill, medium ball mill ball. So usually under normal circumstances, do not need to add the ball. Add the case of the ball is no useful monomer particle size dissociation, when the fining machine fineness less than flotation requirements, you can add the right amount of small ball. Ball mill ball in the process of continuous wear and tear in the course of operation, in order to maintain the ball charge rate and ball a reasonable ratio to maintain the stability of the ball mill operation, we must make a reasonable make up, low compensation wear.
Steel ball added weight, is based on the quality of steel ball, steel ball quality is good or bad, determines the amount of ore tons of consumption, the best use of new wear-resistant steel ball, such as the train wheel by a special treatment forged steel Ball is very wear-resistant.
