Two rotors in the mixing chamber rotate at specific speed ratios, capturing material from the feeding port and directing it through the roller gap. Here, the material undergoes squeezing and shearing. After passing the gap, it strikes the sharp edge of the "W"-shaped mixing chamber, splitting into two streams that flow along the front and rear chamber walls before returning to the rotor top. Within the sealed chamber, materials are subjected to intense shearing and mixing under controlled pressure and temperature, ensuring optimal dispersion, plasticization, and formula performance.

In the mixing chamber, the paired rotors turn at fixed speed ratios, drawing feedstock from the intake and forcing it through the nip between the rolls, where compression and shearing take place. Once through the nip, the material hits the pointed apex of the W-configured chamber, splitting into two flows that travel down the opposing walls and then return to the rotor crest. Because the chamber is fully sealed, the mix is subjected to strong shearing and homogenization under carefully managed pressure and temperature, ensuring complete dispersion, smooth plasticization, and dependable performance of the formulation.

• Changfeng's anti-leakage powder device uses mechanical shaft seal tightening with self-lubricating seal rings, maintaining compression and sealing during operation. This reduces wear and minimizes noise from leakage.
• Through-type heating system provides faster, more uniform temperature transfer, offering 50% greater efficiency than traditional heating plates. Optional PLC program control system available.
• Complex tube belt design in the mixing chamber ensures excellent heat exchange and precise temperature control. Water-cooled rotors prevent material sticking, enhance temperature accuracy, and promote even dispersion.
