Our sizers are based on the results of research conducted by Fredrik Mogensen, Ph.D., Engineering.

Det revolutionerande genombrottet kom 1947 då han byggde prototypen för den första Mogensen Sizer, enligt principen att olika stora partiklar har olika stor sannolikhet att passera en siktduk, även när partiklarna är mindre än siktdukens maskor. Lutande plan på siktdukarna ger bättre effekt och ökad kapacitet.
The revolutionary breakthrough came in 1947, when Fredrik Mogensen built the prototype for the first Mogensen Sizer, based on the principle that differently sized particles have different probability of passing through a screen cloth, even when smaller than the mesh openings of the screen cloth. Sloping the screen decks produces a better effect and increases the capacity of a specific area.

Mogensen’s international expansion gathered momentum in the 1960s and today we are represented in Europe, Asia and North America. The company moved to Hjo in 1970 and in 1995 we became part of the German Group, Allgaier Werke GmbH.
