Raw material e.g. granular material, separating device for use in grinding plant, has static separator with aeration base through which gas flows, where base is arranged in vertical direction and has specific ratio of breadth to height

摘要

The device has a static separator (1) with an inclined aeration base (1a) through which separator gas (2) flows, where the aeration base is arranged in a vertical direction. An inlet opening (3) feeds raw material (9) to the aeration base, and an outlet opening (4) is provided for coarse particles. A downstream dynamic separator (5) has a rotor (5a) and another outlet opening for the separator gas loaded with fine particles. A ratio of breadth to height of the aeration base is 0.6.
