    摘要： A process for producing lubricating, stabilising additive mixtures in the form of powder-free flakes with good flowability and dispersibility characteristics comprises compressing and heating a pulverulent mixture of additives to obtain a dense, ductile mix which is then extruded, cold or hot-rolled, then reduced to flakes, and finally blown countercurrently in order to separate the powder from the flakes.
    A plant for implementing the process comprises a screw extruder (3, 4, 5) provided with successive heating elements (T 1 , T 2 , T 3 , T 4 ) operating at increasing temperatures, a cold roller mill (7) arranged to reduce into strips (66) the filaments (6) produced by the extruder (3, 4, 5), a device (8) for crushing the strips (66) into flakes, and a powder-separation cyclone (11) which eliminates the powder from the finished product.
