Types Of Ball Mill
What are the ball mill types?
Types of ball mill are the key grinding equipment after material being crushed. The common ball mills classifications are many, one of the most practical classification methods is based on the grinding media to differentiate, such as the classical grinding ball mill is base on metal ball grinding media; roll mill use still bar as grinding media to grinding materials. There are some autogenous tumbling mills uses the grinded ores body by itself as the grinding media, such as pebble mill is base on gravels as grinding medias, or the grinding medium with ceramic is called ceramic grinding mill, others like cement ball mill, coal ball mill etc.
Ball mill classification with grinding media
Common Ball mill
Grinding media is mainly steel ball or steel segment. This type mill is the most common using.
Also called pin mill. The grinding machine set steel bar as grinding media in diameter-within 50-100 mm. The rod mill ratio of the length of the diameter of 1.5-2 general
Rod ball mill
This types of mill usually has two to four cabins, and input cylindrical steel bar as grinding media in the first cabin, the others cabins to load steel ball and steel segment. The long diameter ratio of the rod ball mill type should better about 5. The bar length is usually shorter than cabin about 100mm for steel bar parallel range and avoid cross or chaotic.
Pebble grinding mill
this type of ball mill can use gravel, pebble, and ceramic ball as ball grinding media. It’s most used for white or colorful cement and ceramic manufacturing.
Ball mill types classify by length
Short ball mill
It’s the traditional ball mill and draw ratio is less than 2. This type of ball mill is single cabin and most used for coarse grinding or primary grinding, it also can be used in series with more than two ball mill machines.
Medium length ball mill
The draw ratio is around 3.
Long grinding ball mill
It’s also called tube mill because the draw ratio is more than 4. Both the medium ball mill and long grinding mill is divided two to four cabins inside, they are widely used in cement plant.
Three types of ball mill accords discharging method
Overflow type ball grinding mill
Grinded ores unrestrained overflow by the hollow shaft neck of discharge mouth.
The grinded product discharged by holds between grid plates and output through hollow shaft neck finally.
Besides, there is some ways to differentiate ball mills types according to cylinder driving modes: surrounding gear transmission, friction transmission and center driven, the first mode is the most used and tube mill is most used center driven way.
The ball mill support ways of cylinder driving also have three methods: bearing support, idler pulley support, bearing and idler mixed support. Thereinto, bearing support method is the most widely used, and the after two methods is usually used in pebble mill.
In addition, there is web ball mill and dry ball mill, mining ball mill, saving energy ball mill etc. We are professional grinding ball mills manufacturer and provide types of ball mill for sale. Any questions please contact us.
