Olwyn malu wedi'i rannu'n bennaf yn dri chategori, dosbarth A, dosbarth B a dosbarth W.
A: a ddefnyddir yn bennaf mewn dyddiau castio, dur, prosesu metel a diwydiannau cerrig a diwydiannau eraill.
B: dosbarth llafur mawr, diwydiant llwydni.
W: Defnyddir dosbarthiadau ar gyfer malu manwl.
Defnyddir yr olwyn malu mewnol yn bennaf ar gyfer malu tyllau, sy'n un o'r malu anoddaf. Yn ddelfrydol, diamedr allanol yr olwyn malu yw 60-80%. 、
Malu cylchgrwn yw'r ffyrdd malu mwyaf cyffredin, a ddefnyddir ar grinder ysgarth. Arwyneb cylch allanol olwynion malu yw'r wyneb sy'n gweithio. Defnyddir yr olwynion yn bennaf ar gyfer falf, Siafft Gyrru, dwyn ac ati. Yn unol â'r priodweddau materol, ansawdd yr wyneb a manwl gywirdeb geometrig y darn gwaith, gellir dewis yr olwyn malu sy'n cyfateb i'r perfformiad.
