In this way, also bulk material in the center of the bulk material flow is reliably moistened.
  • the water nozzles arranged at this level do not yet achieve complete humidification of the bulk material flow, because there is a gap between two adjacent water nozzles in which no water impinges on the bulk material flow. These gaps are covered by the second-level water nozzles arranged at an angle, so that the water nozzles of the two levels in total cause the bulk material flow to be completely moistened.
  • the device according to the invention can thus be used advantageously for different types of bulk goods.

This embodiment can be combined with the other features of the invention.
  • An effective humidification of the bulk material flow requires that the water penetrates into the bulk material flow. This is promoted when the water nozzles are in pairs in a plane opposite. This feature preferably applies to all water nozzles of a plane, more preferably to all water nozzles of the device according to the invention. By acting from two opposite directions water is ensured that the water penetrates into the bulk flow, instead of pressing it against the opposite wall. A similar effect can be achieved if the water jets are uniformly distributed over a level over the circumference of the downer. With an even number of water nozzles, this automatically leads to two water nozzles facing each other. But if, for example, three water nozzles are provided on one level, then these are offset by 120 ° to each other.
