General diameter of ball mill is in accordance with a formula:
5 times of feed particle size, such as,if the feed granularity is 20 mm,the steel ball generally choose 100 mm.
4 times of feed particle size , such as, the feed granularity is 20 mm,the steel ball generally choose 80 mm.
Choose to conform to the first paragraph above ball mill, the second paragraph should add some balls. Minimum but not less than 10 mm, less than 10 mm steel ball for grinding doesn't work.
The experience For the first time to choose a steel ball according to the following methods.For the first time to choose steel ball,the maximum diameter should about 80% with the ball.Add again after a few days to be functioning steady, namely the size of gears running-in.The commonly used ratio is as flollow:
We can additional add different types of steel ball according to the production situation subsequent.
