a cyclonic comminuting device includes a set of shearing plates that is adaptable to any colloid mill for improved efficiency and effectiveness in the production of all commodities including , but not limited to , asphalt or bitumen modification , tar , plastics , polymers , cosmetic processing and foods processing . the set of shearing plates includes a set of concave cutting edges . the set of concave cutting edges is applied to radial teeth of a rotor plate and / or a stator plate of the set of shearing plates forming a cyclonic flow pattern of a commodity as the commodity is passed through the comminuting device . the resulting turbulence created by the intersecting concave cutting edges on the rotor plate and the stator plate increases the effective hydraulic shear generated by the rotor plate and the stator plate resulting in greater particle pulverization and resulting in higher quality emulsions with reduced cost of materials required for production .
