What type should be chosen when the stirring speed of the reactor is very low?

This reaction vessel is a refurbished unit; it has a volume of 15 m3, the stirring speed is only 28 revolutions per minute, and the stirring type is three-layer frame stirring. It turns out that a large amount of material is used in production (more than 10 tons per batch during the reaction phase, and the total amount exceeds 15 tons after dissolution), so the mixing effect is definitely satisfactory. Now it is being modified to produce another product; during the reaction phase, only 3 tons of material are fed in, and the material does not even reach the second layer of impellers, so during mixing the material moves only in a tangential direction. Since the original mixer has an integrated design that makes modifications difficult, in order to improve the mixing effect, it is planned to install a disc turbine mixer between the blades of the first and second layers. I’m not sure if this is feasible Given the low stirring speed, which would be more effective: installing a disc turbine stirrer or an impeller stirrer? I’ve come specifically to ask for advice! :handshake
