Twin-rotor Powder Classifier
Product Description
When your goal is an ultra-narrow particle size distribution for ultra-fine powder, our Twin-rotor Powder Classifier is the only choice. Evolved from O-Sepa technology, it features a coaxial dual-cage rotor structure. This unique dual-vortex field achieves "secondary dispersion + secondary grading," far exceeding the precision of single-rotor machines. It is the ideal heart for high-end micro-powder production in metallurgy and fine chemicals.
We manufacture these high-precision systems near Nanjing. One customer needed slag powder with a specific surface area exceeding 600m²/kg; our HKX1000 stabilized at 650, helping them enter the high-end market. Buying directly from the source factory gives you a technical partner capable of handling the most complex ultra-fine classification challenges.

FAQ
Q: Does it consume a lot of electricity?
A: On the contrary, its high precision reduces ineffective material circulation, lowering the total energy consumption per ton for the entire line.
Q: Is there installation guidance?
A: We provide logistics and installation plans and send personnel to train your operators.
