#### How Many Balls in a Ball Mill? JXSC Machine

How many balls In general, the ball volume of the ball mill steel ball is lower than the horizontal line in the cylinder. It is better to control the ball amount at about 40-50%. For smaller ball mills, the ball balls accounts about 35% at best, this can effectively ensure that the steel ball can fall freely, so that creates a larger impact force.How Many Balls In Ball Mill Crusher Mills, Cone Crusher,Ball Mill Grinds 6 Pounds of Material Wedding sparklers You will need 200 1/2-inch balls per mill jar: This ball mill does need to have a small modification made to it in order to make it mill efficiently.
