Abstract
A method of reducing the liberation of dust particles from a dry particulate matter is disclosed. The particulate matter is transferred to a location where it falls through the air, a small amount of water is introduced onto the particles of material in the material stream, the water being added in the amount of at least 1.01 % and no more than 1% of the weight of the dry particulate matter. The wetted particles contact each other and are distributed generally uniformally throughout the remainder of the material. The delivery of the wetted particles is delayed by a period of at least one second. A smooth path is provided for the material stream after the uniform distribution and prior to discharge at the discharge location.
