It is strictly forbidden to overload the ball mill and cause strong impact and vibration. 03 The liner of the ball mill is broken. When the ball mill is running, the liner breaks, which is probably caused by the unreasonable ball filling rate and proportion. When the charging rate of steel balls is low, the steel balls will wear more on the liner.

Problem 6: Abnormal running sound of ball mill reducer. Solution 6: The sound of the normal operation of the ball mill reducer should be uniform and stable. If there is a slight knocking sound or hoarse friction sound on the gear and there is no obvious change during the operation, you can continue to observe and find out the cause, and stop ...

Starting and Stopping. In starting the grinding circuit after anything but a very short shut spitars enough to clear the same packed on the tank bottom, start the classifier overflow pump, then start the classifier, and after that, the ball mill. But don't throw in all these switches at once.

2. Energy consumption Choose an energysaving ball mill or ordinary ball mill according to the capacity of electric power supply and energy consumption limitation. 3. Capacity If you require high capacity, choose a continuous ball mill. The vibrating feeder can automatically feed, so the continuous ball mill can keep running for 24 hours.

If the ball mill is running at low load, the steel balls will directly impact the liner, causing serious wear and even breakage of the ball mill liner. Solution: Relevant staff need to adjust in time according to the running state of the ball mill. When the ball mill is running under a low load state, it is necessary to adjust the ore input of ...

Running a pilot ball mill circuit can overcome this problem but this requires a reasonably large sample and therefore can be costly. In addition a valid scaleup procedure is required. To overcome these limitations in using modelling and simulation for designing ball mill circuits, a programme of research was initiated at the JKMRC in which it ...

Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent of critical speed. Rod mills speed should be limited to a maximum of 70% of critical speed and preferably should be in the 60 to 68 percent critical speed range.

Overview of Ball Mills. As shown in the adjacent image, a ball mill is a type grinding machine that uses balls to grind and remove material. It consists of a hollow compartment that rotates along a horizontal or vertical axis. It's called a "ball mill" because it's literally filled with balls. Materials are added to the ball mill, at ...

In the ballandrace mill (Fig. ), balls are held between two races, much like a large ball top race or grinding ring remains stationary while the bottom race rotates. As the coal is ground between large diameter balls and the ring, the balls are free to rotate on all axes and therefore remain spherical.

The mill, with its heavy weight, rests statically on the slide shoe surfaces. To lift the mill a highpressure pump pumps lubricating oil into the space between the mill shell and the bearing. This process is referred to as hydrostatic lubrication. When the mill rotates the movement of the mill running surface creates hydrodynamic lubrication.

Ball consumption varies with the fineness of the product, hardness of the ore, quality of ball, and whether a mill is run in closed or open circuit. The ball, consumption for mills delivering a coarse product, all passing 8mesh and containing 10 to 20 per cent. below 200mesh, the mill being run in open circuit, is about ½ lb. per ton for ...
