Abstract
A high-pressure mixing apparatus for producing and discharging a composite material resulting from a reactive mixture of at least a first and a second chemical components and from a filler material. The apparatus includes a main body, provided with a discharge duct for the composite material, at least one high-pressure mixing chamber for the chemical components and a first cleaning member axially displaceable between a forward and a rearward position within the discharge duct. The apparatus also comprises a second cleaning member with a control device selectively actuable to sequentially move the first and the second cleaning member between the rearward position, in which the first cleaning member opens the discharge duct, and the forward position in which the facing annular surfaces of the discharge duct and the second cleaning member are mutually abutting to eject the residual reactive mixture and close the exit port of the mixing chamber.
