Why SMIDA Planetary Centrifugal Mixers Mix in Seconds, Not Minutes1
Have you ever watched an impeller mixer struggle with a thick paste?
The blade spins, but the material at the center barely moves.
Shear is generated at the blade edge and dies out quickly with distance.
The thicker the material, the less the blade reaches — so the machine just spins longer, heats the batch, and eats floor time.
A planetary centrifugal mixer works differently.
It does not push material with a blade — it spins the whole batch.
The Physics of Speed
Each sealed cup revolves around the machine's central axis while rotating on its own axis:
•Revolution creates centrifugal force that acts on every particle at once, compressing the batch and driving it outward — there is no unmixed center;
•Rotation generates shear at the cup wall, dispersing agglomerates while the batch keeps turning;
•Vacuum degasses in the same cycle, so mixing and degassing are one step, not two.
With the entire batch under load in every rotation, a SMIDA mixer disperses high-viscosity pastes in tens of seconds to a few minutes — work that takes impeller mixers half an hour or more.
What Faster Mixing Buys You
•Higher throughput — a 30-minute cycle cut to 3 minutes multiplies batches per shift;
•Less heat input — shorter processing protects heat-sensitive materials;
•Fewer operator errors — recipes are stored digitally and recalled with one touch.
The dual-cup design doubles productivity again: two batches in the same cycle, or two formulations side by side in R&D.
Quick Answers
How fast does a SMIDA mixer run?
Revolution speed is adjustable from 200 to 2000 rpm with independent revolution/rotation control.
Does high speed damage materials?
No blades touch the material, so shear is gentle and even — flakes, fibers, and polymers keep their structure.
What capacity is available?
Mixing volume 1 g to 100 kg+, equipment range 150 g to 100 kg+, with vacuum, temperature-controlled, and non-vacuum models.
