A method and a device for making a multi-components product material

A method for making a multi-components product material, the method comprising:

• a) supplying some, but not all of primary particle components for homogenizing thereof into a processing chamber as a first batch;
• b) supplying a heating agent into the processing chamber to heat at least partly the primary particle components,
• c) using in the processing chamber at least two rotary sets of shovels, each with a plurality of rotary shovels on a common rotary shaft in order to homogenize the primary components of the first batch, 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;
• d) delivering in at least one step in at least one of:
• a fluid state and/or a fine particulate material state, at least one secondary component to let it interact with said first batch of primary components in the chamber while these primary components are moved around in the processing chamber by the sets of the rotary shovels;
• e) supplying a second batch of primary particle components into the processing chamber for homogenizing thereof, by means of said at least two sets of shovels, with the first batch of primary components therein,
• f) further delivering in at least one step in at least one of:
• a fluid state and/or a fine particulate material state, a further supply of said at least one secondary component into the chamber to let it interact with said first and second batches of primary components while these primary components are moved around in the processing chamber by the sets of the rotary shovels, and
• g) discharging from the chamber as the multi-component product material the first and second batches of primary components as interacted with the secondary component(s) in a homogenized mixture, the discharged multi-component product material (10″) which exits the processing chamber (10′) being directly delivered to a downstream product finalizing stage (11) to yield a final product (12) thereof by pressure moulding.

A device for making of a multi-components product material, comprising:

• a processing chamber with at least one supply inlet for primary particle components, said chamber configured to homogenize the primary components;
• at least two sets of rotary shovels, each set with a plurality of rotary shovels on a common rotary shaft in order to homogenize the primary components in the chamber, 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;
• inlet(s) into the chamber for at least one secondary component in a fluid state and/or fine particulate material state, e.g. powder, and which is to interact with said primary components in the chamber while the primary components are moved about in the processing chamber by sets of the rotary shovels, and
• an outlet in a bottom region of the processing chamber to allow the primary and secondary components to be discharged from the chamber as the multi-component product material,
• wherein at least one heating agent inlet into the processing chamber is provided to let a heating agent enter the processing chamber to heat at least partly primary components therein, and
• wherein the bottom region outlet is directly upstream of a product finalizing stage being a pressure operated mould to yield a final product of said multi-component product material.
