Operation Regulation of Ball Mill
The purpose of the Ball Mill is to grind materials. The Ball Mill is composed of the components like the cylindrical shell, feeder, main bearing,
mill base, gear belt drive lube system, charging and discharging systems, and the electrical control part.
Before using the Ball Mill, all the safety regulations should be followed and workers who work around the Ball Mill also should obey the safety
regulations strictly.
1. Pre-operation inspection
All the users of the Ball Mill must inspect the machine carefully before start the machine and make sure that the machine is in good condition or
not.
2. Start and stop
When the machine is started, open the working flow valves and regulate the pressure, then start the Ball Mill. Before loading material, check whether
the gear is rightly matched. If not, the Ball Mill will be damaged due to overload and material may leak out.
When the machine is stopped, close all the valves, the lubrication and cooling systems.
3. Loading and unloading materials
The materials should be loaded and unloaded properly, or the Ball Mill will be damaged.
The feed should be put evenly and continuously, and it should not contain other hard matter such as nail, clip or steel ball.
The feed should be clean, to reduce the difficulty of loading and avoid the collision of the steel balls.
The amount of feed should not exceed the rated feed amount in normal operation, or the output will be affected.
Stop feeding when the materials meet the discharging opening, that is to say, no more materials can be seen in the Ball Mill, so as to prevent over-
grinding.
4. Maintenance and repair
The Ball Mill should be greased and lubricated regularly.
Regularly check the cylinder to make sure that it is in good condition.
The lubrication and cooling systems should be checked before start-up and shut down.
Check for gap of the lining plate and the liner, which will affect the output.
5. Faults treatment
When the machine is in abnormal situations such as vibration caused by overload, reduce the amount of feed and stop the machine.
When the Ball Mill is jammed due to the material entering into it, make sure to stop the machine and check the source of the jam.
When the mill liner and the liner are worn badly, they should be replaced.
When the bearing temperature is too high, the bearing must be cooled down.
6. Notes
It is forbidden to work on the machine when it is running.
It is forbidden to bring the materials over the discharging opening.
It is forbidden to fill liquid into the Ball Mill.
It is forbidden to weld on the Ball Mill.
7. Emergency stop
In case of emergency, press the emergency button and the machine will be stopped. Inspect the situation carefully and take actions according to it.
These are the operation regulations for Ball Mill. All the users of the Ball Mill must follow these rules strictly to ensure normal operation and to
avoid accidents.
