Q47: How do sigma-blade mixers operate? 🌚
A: They use counter-rotating blades that knead and shear high-viscosity masses.
Q48: What is unique about a planetary mixer? 🥹
A: Double rotation — element rotates around the container and itself, reducing dead
zones.
Q49: What type of mixing do
mulling mixers provide?🙂↔️
A: Kneading, shearing, smearing, and blending, resulting in uniform physical and
chemical structure.
Q50: What is the limitation of mulling mixers? 🙂
A: They are inefficient at uniformly distributing particles in the whole mass.
Roller Mills
Q51: How do roller mills work in mixing? ☝🏻
A: Material passes between rollers rotating at different rates, causing crushing and
shearing.
Q52: Which roller mill type is preferred? 💪
A: Three-roller mills.

Q53: What happens when a small amount of liquid is mixed with a large amount of
solid? 👻
A: The liquid coats the particles; if sticking occurs, paste mixers are used.
Q54: What type of equipment is used if solids remain free-flowing? 🐛
A: Solids mixing equipment.🫂
