5HXZ-3 Specific Gravity Separator is a screening and classifying machine, which screens and classifies seeds of different specific gravity through an operation method combining a two-way tilting and reciprocating vibrating workbench and the air flow across the whole mesh screening surface of the workbench. It is suitable for handpicking wheat, rice, maize, sorghum, other crops seeds and vegetable seeds.

　The machine is composed of a stand, a housing, an air-supply system, longitudinal/crosswise adjustment systems, a vibration system, a screening surface, etc. According to the varieties of crops to be sorted, choose stainless wire screening surfaces with different mesh numbers; adjust the air flow volume of various workbench areas so as to achieve the best flowing status and stratification of seeds on the surface of the workbench.

　　Meanwhile, according to the practical needs, adjust the vibration frequency of the workbench and the longitudinal/crosswise angles, so as to meet various types of seeds’ sorting requirements and achieve a higher degree of purity. The vibration frequency of the workbench features stepless adjustment by a converter. The machine is suitable for processing lines at seeds processing sectors and single-machine operation.

　　A mobile base (frame) can be installed according to the user’s need.
