摘要：The present invention provides a method for the production of free-flowingadditive compounds that comprises the steps of preparation of a particulate additivecompound and storage of a mass of the particulate additive compound at a surfacepressure of at least 30 g/cmuntil the mass of additive compound is baked together. Thenfollows the crushing of the baked-together mass of the additive compound into acrushed particulate additive compound and the sieving of the crushed particulate additivecompound, whereby particles of a size in excess of 4.0 mm and particles of a size of lessthan 0.1 mm are separated from the crushed particulate additive compound such that afraction containing a free-flowing additive compound with long-term stability of particlesizes is obtained.
