The 5XFZ-40D single specific gravity cleaning machine is a composite structure of winnowing and single specific gravity table cleaning; the raw grain enters the vibrating screen to remove large and small impurities; then passes through the rear wind screen vertical air screen to remove light impurities such as dust; The material enters the specific gravity table, and the separation of light impurities and finished products is realized through specific gravity segregation. The impurities with small specific gravity are distributed on the surface and flow to the low end, and finally discharged from the light and miscellaneous port of the specific gravity table. Good materials are distributed at the bottom and flow to the high end. It is discharged from the hopper, and the final product is discharged from the high end of the specific gravity table.

This machine is an important equipment for the selection and processing of grain and agricultural by-products, and can be used for the processing and selection of various granular materials. Under the double action of aerodynamic force and vibration friction, the material produces specific gravity segregation. By adjusting the technical parameters such as wind pressure and amplitude, the material with larger specific gravity will settle to the bottom layer and move to a higher place under the vibration and friction of the screen surface. Smaller materials are suspended on the surface and flow down through the action of airflow, so as to achieve the purpose of separation according to specific gravity.

The material enters the first negative pressure specific gravity platform through the feeding hopper through the conveying equipment, and the dust, chaff and other light impurities in the material are removed by winnowing, and the light impurities pass through the air duct, spiral The dust collector is discharged and collected by the air locker; through the specific gravity selection, the impurities with relatively light specific gravity such as straw and shaft blocks in the material are effectively removed. After that, the material enters the second positive pressure specific gravity platform through the grain guide mechanism, and the specific gravity processing is carried out by adjusting the air volume and the position of the baffle, so as to effectively remove impurities such as broken grains, grains, sprouts, insects, and moldy grains in the material. . The final product is discharged from the high end of the specific gravity table.
