When you want to produce stable emulsions and creams, wet and dissolve sticky powder (gums, thickeners, stabilizers), deagglomerate and disperse micro-phase solid ingredient (silicon dioxide, bentonite, titanium dioxide) into liquid without fish-eyes, or other similar tricky tasks, a traditional agitator is usually not able to achieve the expectation. However, the high shear mixer is what you should choose to do the job.
High Shear Mixers work with a special designed stator/rotor working head. When it works, this stator/rotor head is able to draw the solids and liquids around it into its center, and then push them radially through the stator openings back to the tank. During this period, the solids and liquids are subject to an action of milling and shearing which is so intensive that they are deagglomerated, homogenized and dispersed into each other even though they are immiscible by traditional agitation.
In the Batch process, the mixer is immersed into the liquid. There are many installation methods for the batch mixer. It can be lifted up by a lifting stand (hydraulic or electric), or it can be installed with flange on the top of a tank, or from its side, or at its bottom. For the vacuum or pressurized tank, the mixer must be equipped with a mechanical shaft sealing.
Top entry, open vessel
These mixers are used in an open vessel, that is, a vessel with normal pressure. They are top entry mixers, can be installed onto a lifting stand, or directly onto the vessel by a flange or traverse. A coupling between the motor and shaft is optional for low noise and stable running.
Top entry, closed vessel
These top entry high shear mixers are with a mechanical seal, which enables them to be working in a pressurized or vacuum vessel. Single seal or double seals are available.
Side entry The side entry mixers are very useful when the tank is deep but narrow, or when the top space of the vessel is limited for the top entry ones.
- Bottom entry
The bottom mixers are outstanding when the liquid level in the tank can get very low during the operation, or there is very limited space above or around the tank for either top or side mounted ones. What is more, strong vortex as well as aeration is greatly reduced with the bottom mounted mixers.
High Shear Mixers are widely used by a variety of industries in different stages of the processing. They are highly efficient to save a lot of energy and time compared with traditional mixing methods.
