Ball mill is an efficient machine for powder grinding. And the ball mill is broadly utilised in powder-making production line like cement, new-type developing material, silicate, refractory materials, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc. Ball mills have two techniques of grinding: the dry way and also the wet way. It can be divided into tabular type and flowing kind in accordance with different extracting way of mine. Ball mill is extensively employed in cement sector, mining market, building materials, chemical market and so forth.
How works of ball mill
Cylindrical ball mill is a horizontal rotating device. Material will be fed evenly into the first warehouse where has ladder liner or corrugated liner, built with different specifications of steel balls; centrifugal force will raise the ball to a certain height. After the falling, the material will be seriously impacted and abraded. The material will then enter the second silo which is lined with flat liner for further grinding.
The steps in detail when problems happen in running the ball mill
When the ball mill is running, there is regular beating noise. The temperature of ball mill and reducer is high. When ball mill reducer is driving, there will be a huge vibration. When the ball mill reducer is running, the sound is unusual.
For the common problems in operation, in order to resolve these issues better we should adopt different solutions according to different reasons.
Match of ball diameter is very important: pay attention to the size of ball diameter, which can improve efficiency.
Change the formula is to increase the strength and weight of the ball (to increase its inertia).Grinding time and efficiency have no relationship, because efficiency itself is the ratio of effort and time.
Methods of increasing speed include the use of inverters and modified deceleration device (if there is deceleration device).
Then there is a must to...
