Abstract
An air jigging machine for dry processing of raw materials, an air supply conduit for supplying working air to an air funnel, and having a pulsing valve. At least two jigging-material carriers for receiving material from a material-feeding mechanism are configured to consecutively receive therethrough working air from the air funnel and to separate the material into heavy and light material layers. The jigging-material carriers are disposed one above the other and are spaced apart. A wall encloses this intermediate space. At least one bypass airline branches off from the air supply conduit downstream of the pulsing valve, bypasses the lower jigging-material carrier, and communicates with the intermediate space for supplying an additional working airflow thereto. Respective discharge devices are provided for the jigging-material carriers for the material layered thereon during a jigging process.
