A method for making a multi-components product material, the method comprising: - supplying in at least one step primary particle components ( 4; 5; 6) for homogenizing thereof into a processing chamber; - using in the processing chamber at least two rotary sets ( 13, 14; 13'; 14') of shovels, each with a plurality of rotary shovels ( 15 - 19; 20 - 24) on a common rotary shaft ( 25; 26) in order to homogenize the primary components, the rotary shafts of the at least two sets of rotary shovels being caused to rotate in parallel in a mutually counter-rotating, homogenizing mode; - delivering in at least one step in one of: a fluid state, a fine particulate material state, and a mixture of a fluid state and a fine particulate material state, at least one secondary component ( 7; 7') to let it interact with said primary components ( 4; 5; 6) in the chamber while the primary components ( 4; 5; 6) are moved around in the processing chamber by sets ( 13; 14; 13'; 14') of the rotary shovels; and - discharging from the chamber as the multi-component product material ( 10") the primary components as interacted with the secondary component(s) in a homogenized mixture, characterized in - that the primary particle components and the fine particulate material are made from petroleum coke, - that the secondary component in fluid state is pitch, - that a heating agent is supplied into the processing chamber to heat at least partly the primary particle components ( 4; 5; 6) being homogenized therein and to dry off any unwanted liquid moisture from the primary components ( 4; 5; 6), and - that the discharged multi-component product material ( 10") which exits the processing chamber is directly delivered to a downstream product finalizing stage being a pressure operated mould to enable by pressure moulding a final product being an electrode. - supplying in at least one step primary particle components ( 4; 5; 6) for homogenizing thereof into a processing chamber; - using in the processing chamber at least two rotary sets ( 13, 14; 13'; 14') of shovels, each with a plurality of rotary shovels ( 15 - 19; 20 - 24) on a common rotary shaft ( 25; 26) in order to homogenize the primary components, the rotary shafts of the at least two sets of rotary shovels being caused to rotate in parallel in a mutually counter-rotating, homogenizing mode; - delivering in at least one step in one of: a fluid state, a fine particulate material state, and a mixture of a fluid state and a fine particulate material state, at least one secondary component ( 7; 7') to let it interact with said primary components ( 4; 5; 6) in the chamber while the primary components ( 4; 5; 6) are moved around in the processing chamber by sets ( 13; 14; 13'; 14') of the rotary shovels; and - discharging from the chamber as the multi-component product material ( 10") the primary components as interacted with the secondary component(s) in a homogenized mixture, - that the primary particle components and the fine particulate material are made from petroleum coke, - that the secondary component in fluid state is pitch, - that a heating agent is supplied into the processing chamber to heat at least partly the primary particle components ( 4; 5; 6) being homogenized therein and to dry off any unwanted liquid moisture from the primary components ( 4; 5; 6), and - that the discharged multi-component product material ( 10") which exits the processing chamber is directly delivered to a downstream product finalizing stage being a pressure operated mould to enable by pressure moulding a final product being an electrode.
