the revolution and rotation speed of the blades have been extensively studied and tested to give the mixer a high output without causing the segregation of materials with different grain size and weight.The movement of the material inside the trogh is smooth and continuous .As shown in the picture,the blades track covers the whole bottom of the trough after a cycle.

 1.> the gearing system :the power transmission is realized  by a hard surface gearbox which is designed  specially by our company(this technique has been patened) fluid cluth is installed between the motor and the gearbox. it can keep the mixer start up normally even in the full load condition ,the driving force provided by gearbox drives the mixing arms to do not only a revolution but also a rotation ,and drives the scraping arms have a revolution ,by this drive mode,the mixng action not only has a rotation but also has a revolution ,the more complex of the mixing is ,and then the mixer works more effectively ,its mixing more homogeneous.
