Editing Mixing (process engineering) (section)

===Planetary mixer===
A ''planetary mixer'' is a device used to mix round products including [[adhesive]]s, [[pharmaceuticals]], [[food]]s (including [[dough]]), [[chemical]]s, [[solid rocket propellant]]s, [[electronics]], [[plastic]]s and [[pigment]]s. Planetary mixers are ideal for mixing and [[kneading]] viscous pastes (up to 6 million [[Poise (unit)|centipoise]]) under atmospheric or vacuum conditions. Capacities range from {{convert|0.5|uspt}} through {{convert|750|usgal}}. Many options including jacketing for heating or cooling, [[vacuum]] or pressure, vari speed drives, etc. are available. Planetary blades each rotate on their own [[Axis of rotation|axes]], and at the same time on a common axis, thereby providing complete mixing in a very short timeframe.<ref>[https://www.china-ashine.com/what-is-a-planetary-mixer-types-functions-how-to-work/ What is a Planetary Mixer? Types, functions & how they work], 28 October 2028</ref>

Large industrial scale planetary mixers are used in the production of [[solid rocket fuel]] for long-range [[ballistic missile]]s.  They are used to blend and homgenize the components of solid rocket propellant, ensuring a consistent and stable mixture of fuel & oxidizer.<ref>[https://mil.in.ua/en/news/israel-hits-ballistic-missile-production-facility-in-iran/ Israel hits ballistic missile production facility in Iran], Miliarynyi, 27 October 2028.</ref><ref>[https://newsukraine.rbc.ua/news/israeli-strike-cripples-iranian-missile-production-1729995076.html Israeli strike cripples Iranian missile production], RBC-Ukraine, 27 October 2024.</ref>
