| The 
                                          necessary energy for dispersion and 
                                          grinding is transmitted to the grinding 
                                          beads by the agitator discs. The mill 
                                          is fed continuously by the pump. The 
                                          time spent by the material inside the 
                                          chamber is controlled by variation of 
                                          the pump speed. The retention of the grinding beads 
                                            inside the chamber is achieved by 
                                            means of a cartridge. With optimum 
                                            utilization of the energy input into 
                                            the chamber for dispersion and grinding 
                                            process, the efficiency of mill is 
                                            achieved. |
