Mixing: High-Shear Mixer
Said to generate a level of shear usually reserved for high-pressure homogenizers.
The patented MegaShear from Ross is an ultra high-shear rotor/stator said to be ideal for high-throughput emulsification, dispersion and homogenization.
The 11,300 ft/min tip speed and proprietary geometry of the MegaShear mixing head generate a level of shear typically unseen among rotor/stator mixers and usually reserved for high-pressure homogenizers. The Ross MegaShear Model HSM-706M-50 is the photo features a 50-hp motor, is mounted on a movable pallet, and is CE marked. A comparably-sized MegaShear reportedly costs considerably less than a high-pressure homogenizer while being much less sensitive to clogging and changes in viscosity.
Improved clarity and cost competitiveness, added to its inherent heat resistance, are reviving OPP’s prospects in hot-fill barrier containers. But hot-fill PET containers are raising the bar with higher productivity and ‘panel-less’ bottle designs.
Start by assessing the status quo, as well as defining future needs. Develop a five-year projection of materials and required capacities. Short-term solutions very often prove to be more expensive and less satisfactory after a period of time. Most of all, know your options.
Newer specialty slip masterbatches go beyond traditional capabilities to provide greater thermal stability, reliability, and ability to hold COF steady during laminating.
