overflow ball mill mill equipment is the more typical one Raymond Mill, because the overflow ball mill in a multi-stage grinding operations can be used. Usually overflow ball mill is mainly used for grinding work second and third paragraphs, but in some special cases can also be used for the first stage of grinding operations.
overflow type ball mill mineral particle size generally less than 0.2mm, so it is mainly applied to the two-stage grinding process in the second paragraph of grinding or regrinding intermediate products (ie third grinding). If, when the overflow-type ball mill diameter greater than 3.6mm, and its products will be a slight increase in size, then you can use the first paragraph of grinding overflow type ball mill.
