It is specifically used to regularly feed granular or powdered products to a machine or conveying element at an appropriate flow rate, particularly in flour mills, to return unwanted product back into the system, and to regulate flow in areas where product movement is difficult.

The machine consists of two main structures. The first part is made up of a semi-cylindrical body and includes a vertically mounted rotor with moving blades, a motor drive unit, and a product passage sensor that controls the inlet and outlet pipes.
