Zur Zeit werden Refiner meist in der Bauform der (Doppel-) Scheibe ausgeführt. Die Nachteile des Doppelscheibenrefiners sind die sich verändernde relative Geschwindigkeit entlang der Mahlzone, eine relativ hohe Leerlaufleistung und besonders bei niedrigen Durchsätzen Probleme mit der Zentrierung des Rotors. Weiters sind auch Kegelrefiner eingesetzt, wobei die bedeutendsten Nachteile dieser Ausführung die schlechte Pumpwirkung sind. Daraus folgen Durchsatzprobleme und in weiterer Folge die Notwendigkeit, die Nuten in den Mahlzonen zu vergrößern, was eine Verringerung der Kantenlänge bewirkt. Als weitere Nachteile können die relative Verschiebung der Messer beim Anstellen zueinander, die Notwendigkeit einer robusten Bauweise aufgrund der auftretenden Lagerkräfte und der Schwierigkeiten beim Garniturwechsel gesehen werden.At the moment, refiners are mostly in the design of the (double) disc executed. The disadvantages of the Doppelscheibenrefiners are the changing relative velocity along the grinding zone, a relative high idle power and especially at low flow rates problems with the centering of the rotor. Furthermore, cone refiners are used, the most significant drawbacks of this embodiment are the bad ones Pumping action are. This results in throughput problems and in more Follow the need to enlarge the grooves in the grinding zones, which causes a reduction of the edge length. As other disadvantages can the relative displacement of the knife when hiring each other, the Necessity of a robust construction due to the occurring Lagerkräfte and the difficulties seen when changing the set become.
Ebenfalls bekannt sind sogenannte Zylinderrefiner, wie sie z. B. in der US 5,813,618 beschrieben sind.

Fig. 1 zeigt schematisch den Anstellmechanismus bei einem Refiner mit
Einfachzylinder. Er besteht aus einem axial verschiebbaren Keilträger 1
und einem radial verschiebbaren Keilträger 2, an dem sich eine Mahlplatte
5 befindet. Die Gegenmahlplatte 5' befindet sich am Rotor 4. Die
Kraftübertragung des Anstellmechanismus erfolgt entlang einer schiefen
Ebene. Wird nun der Keilträger 1 axial verschoben, so ergibt sich durch
die Kraftübertragung am Keil eine radiale Verschiebung des Keilträgers 2.
