The blast wind shifter consists of a circulation extension unit, a separation drum unit, a conveyor, a diffusion chamber, and a dust collector. Operating on the principles of aerodynamics, this equipment employs controllable airflow as the medium for sorting. With the aid of controllable airflow, materials are separated based on density and particle size. The airflow can carry lighter materials upwards or horizontally to a distant location, while heavier materials either fall due to lack of support from the updraft or are propelled closer horizontally due to inertia. This wind sorting process leverages the settling characteristics of various solid wastes in the air to achieve the objective of classification, recycling, and reuse.
