Vertical Air Drafting Duct
The vertical air drafting duct is mainly applied for separating light impurities from raw grains, such as grain husk, empty grains, grass seeds, sand and dust. It is usually used with vibrating sifter
, plane rotating sifter and other cleaning equipment. It is designed according to the their screen width for better supporting use with other grain cleaing equipment.
Vertical Air Drafting Duct Working Principle
This machine is usually working with vibrating screen, rotary flat screen
and other grain cleaning equipment, so the raw grain is conveyed into it through the screening equipment, and the light impurities are removed by the airflow in the air duct for the different suspension velocity of raw grain and foreign materials.
