摘要： The present invention provides a method for the production of free-flowing additive compounds that comprises the steps of preparation of a particulate additive compound and storage of a mass of the particulate additive compound at a surface pressure of at least 30 g/cm2 until the mass of additive compound is baked together. Then follows the crushing of the baked-together mass of the additive compound into a crushed particulate additive compound and the sieving of the crushed particulate additive compound, whereby particles of a size in excess of 4.0 mm and particles of a size of less than 0.1 mm are separated from the crushed particulate additive compound such that a fraction containing a free-flowing additive compound with long-term stability of particle sizes is obtained.
