Influence of Stress Mechanism and Intensities on Product Properties in Solid MixingIn solid mixing a characteristic specific power is entered in the bulk solid. This power can cause change of product properties of the involved components. Here, especially operating stress mechanism and intensities determine if required mixing tasks can be fulfilled and desired product properties can be generated. How stress mechanism and intensities are coupled with product properties is unknown so far.
Enhancement of Product Performance by Intensive MixingThe limitation of raw materials raises the question how those can be utilised efficiently, if there are no economical beneficial alternatives available or if raw material inventions do not represent better solutions. Furthermore, the unit operations of mechanical process engineering for raw material preparation should to be questioned concerning to its energy efficiency. Operators as well as manufacturers of procedural plants and apparatus have to face up to the before mentioned questions.

Diskontinuierliche Feststoff-Mischprozesse werden weitestgehend über die Mischzeit geführt. Dabei wird die erforderliche Mischzeit häufig in Mischversuchen separat ermittelt. Ob diese dem Optimum entspricht, bleibt offen. Es fehlt an Modellen zur Beschreibung des zeitlichen Mischgüte-Verlaufs. Der vorliegende Beitrag fügt ein einfaches, zweiparametriges Modell hinzu, das neben dem Homogenisier-auch den Segregationsprozess berücksichtigt. Damit können mögliche Mischgüte-Optima mithilfe weniger durchgeführter Mischversuche approximiert werden.
