Device for laying dust contained in a bulk product

Abstract

A device for laying dust contained in a flow of bulk product during transfer thereof includes a divergent cone onto whose outside surface the product is directed from a feed pipe to form a tubular layer of product. A mounting device holds the cone in the flow of product leaving the feed pipe and at least one device fixed to the mounting device sprays a moistening liquid to moisten the inside envelope of the layer of product. The spray device has at least one central nozzle in a spray moistening area downstream of the cone to moisten the part of the inside envelope of the product layer downstream of the cone. The structure of the device is such that the thickness of the tubular layer of the flow of product can be freely chosen at least until the flow leaves the area, the layer thereafter retaining its hollow annular shape. Applications include laying dust contained in grain when it is transferred into cells of a storage silo.
