  • Publication number: 20020015356
    Abstract: Method for moistening or wetting bulk material The invention concerns a method for moistening or wetting bulk material. The fluids or pastes are thereby cooled down below their solidification point before being mixed with the bulk material to be wetted. During mixing or after mixing with the bulk material, moistening or wetting is carried out through re-liquidization of the solidified fluids or pastes. This method permits uniform and agglomerate-free moistening or wetting of bulk material.
