PROBLEM TO BE SOLVED: To provide a bead mill for pipeline, with which secondary aggregated materials can be preliminarily dispersed in a sending liquid without precipitating them in a pipeline for sending a solid-liquid slurry solution. SOLUTION: A material supply port (3) is arranged on one side of a dispersing chamber (1) and a material discharging port (4) on the other side, and the ports (3) and (4) are respectively connected to the pipeline (L) so that a material to be treated is made to flow through the chamber (1). A treating gap (21) is formed in the dispersing chamber (1) by an outer peripheral stator (18) and an inner peripheral stator (20) for housing a dispersion medium (10), etc. A rotor (24) is inserted into the treating gap for circulating the dispersion medium on the inner and outer surfaces of the rotor by rotating the rotor. An outflow port (19) is formed on the stator existing on the inside of the rotor and a screen (32) is disposed so that the dispersion medium is not discharged from the port (19). The diameter of the dispersion medium (10), etc., is approximately two to four times that of a dispersion medium used in the wet-type dispersion device in a finishing process and the material to be treated is surely and preliminary dispersed in the chamber.
