Example application of the Laplace transformation for a continuous mixing process in the amixon® AMK 1000 mixer: Powder A flows constantly into the mixer at a rate of 1,000 kg/h. Powder B is dosed simultaneously at a rate of 10 kg/h. The mixing chamber remains closed at the start. The mixing tool is already running and achieves ideal mixing quality after 20 revolutions. It rotates at 20 rpm.

As soon as 700 kg of product are present in the mixer, the discharge valve opens. The discharge is adjusted so that the incoming 1,010 kg/h are also discharged again. The process runs smoothly.

Suddenly, a malfunction occurs: the supply of component B stops completely for 20 seconds. Afterwards, the dosing device is corrected and B flows at double the rate (20 kg/h) for 20 seconds. The flow then stabilises again at 10 kg/h.

Before the malfunction, the mixing quality was technically ideal. The coefficient of variation for the mixing quality was 3%.
