PCT No. PCT/DE96/01442 Sec. 371 Date Apr. 21, 1998 Sec. 102(e) Date Apr. 21, 1998 PCT Filed Jul. 24, 1996 PCT Pub. No. WO97/05439 PCT Pub. Date Feb. 13, 1997A process for feeding bulk material onto a belt of a rotary hearth furnace, which has hoods that cover the hearth belt in such a manner as to form a ring. The bulk material is deposited on a transport device at a layer thickness proportionately dependent on the distance to the rotary hearth center. The transport speed of the transport device is set at a certain value; the surface of the bulk material is smoothed; and then the bulk material is distributed at a constant layer height over the entire width of the hearth belt.
