Disclosed is a blowing device for a rotary air lock, comprising a flushing gas stream that is fed by a gas supply line () in order for adhering material to be flushed and blown out of at least one compartment (-) of the rotary air lock (-) when said compartment is located next to a product outlet of the rotary air lock. A blowing unit (), which comprises at least one blowing tube () and is located in a feeding shoe () that is arranged at the product outlet, directs the flushing gas stream to at least one compartment (-) of the rotary air lock.

A star feeder for conveying all types of bulk materials having a comminuting insert for crushing bulk material agglomerates (). Bulk material agglomerates are conveyed into the inlet of the star feeder () and there pass through the comminuting insert (), which comprises at least one shearing wall (), which includes at least two mutually angled shearing surfaces (), which widen upward, toward the inlet direction () and meet centrally in the region of at least one feed edge ().

A diverter valve having an improved transition at the connecting branches, wherein one inlet and two outlet ports are formed and a cylindrical rotary valve incorporating a straight inner pipe is provided. In order to attain the smoothest possible transition between the rotary valve and inlet and outlet ports of the housing, the invention provides that all three inlet and outlet ports, as well as the respective opposed contour of the rotary valve bore are executed with the same shape, and that in the passage bore of the diverter valve in the region of the inlet and of the two outlet ports two pocket-like shaped surfaces on the housing that are formed mirror-symmetrical relative to the longitudinal center axis are worked into the material of the diverter valve in each case in the form of a pocket-like recess, wherein these shaped surfaces that are fixed to the housing have opposed shaped surfaces in the rotary valve connecting to them smoothly and seamlessly, which are worked-in recessed into the material of the rotary valve.
