A material wetting system for wetting a powder material includes a liquid supply system, a material mixing unit, a material supply system, and a shroud assembly. The liquid supply system includes a supply line. The material mixing unit is in fluid communication with the supply line and includes a central cavity having an open upper end configured to receive a supply of powder material. The material mixing unit is configured to receive liquid from the supply line and is operatively connected to a reduced pressure source to draw air into the central cavity. The material supply system includes an orifice and is configured to feed powder material through the orifice, with the orifice disposed above the central cavity of the material mixing unit. The shroud assembly is disposed about the open upper end of the central cavity of the material mixing unit and the orifice of the material supply system.

A hopper system for powder material includes a hopper and a cover. The hopper has hopper sidewalls that extend downward from an upper end of the hopper with at least one of the hopper sidewalls being sloped along a portion thereof. A hopper axis extends vertically between at least some of the hopper sidewalls. The cover is disposed at the upper end of the hopper and includes an opening configured for the powder material to flow therethrough and into the hopper. The opening defines a vertical material loading axis that is offset relative to the hopper axis. A diverter member may be provided that is positioned along the material loading axis and configured to divert the powder material entering through the opening. A powder material feed system may be disposed adjacent the lower end of the hopper to feed the powder material from the hopper.
