In shear mixing, for example, the separation of individual CNTs from bundles is achieved in shear flow induced by the rotation of an extrusion in a polymer solution or melt. Usually, dispersion via shear mixing is only achievable for specific types of MWCNTs, with a high shear rate in a rather viscous medium.

Some polymers such as SBS are more difficult to dissolve/disperse & require high shear to achieve a satisfactory mixing time. Our jacketed in-line mixers attain this. The bitumen/polymer mix is recycled through the in-line homogenizer where the high shear rotor/stator work head rapidly disintegrates the polymer pieces.
— The detachment behavior of a polymer melt from the hot roll surface/s during roll-driven processes affects the maximum production rates achievable in various processes including calendering, embossing and shear roll milling. Here the continuous shear roll milling process is used to investigate the conditions that lead to the detachment of the …

— A shear mill (D) breaks up polymer granules and mixes them with bitumen. Then, the concentrated PMB is transferred to a dilution tank (F). Fresh bitumen is added to make dilution to the specified PMB properties and agitated to form a homogenous mixture. Generally, it should be stored for at least 8–12 h to fully dissolve the polymer granulate ...
