Dynamic Separator Manufacturer -Greenfield Tech Projects
A Dynamic Separator is an industrial machine that sorts materials by a combination of size, shape, and density. It works by injecting the material stream to be sorted into a chamber that contains a column of rising air. Inside the separation chamber, air drag on the objects supplies an upward force that counteracts the force of gravity and ...

Raw meal particles selection is achieved in the dynamic separator level above the mill. The product fineness is continuously regulated by the operator in the cement plant's control room by acting on the dynamic separator speed and mill gas flow. In other terms, it acts on the centrifugal and aerodynamic forces to reach fineness setpoint.
