                               Continuous ball mills are 
                                used wherein the finished product is obtained 
                                from a single pass through the mill. This type 
                                of operation produces a wide particle size distribution 
                                with a high proportion of superfines in the product. 
                               
                              Continuous ball mills require 
                                careful selection of length/diameter ratio of 
                                the mill to ensure correct residence time and 
                                product fineness. 
                               
                              These are designed for continuous 
                                operations and produces a relatively coarse product 
                                with minimum generation of superfines.
