ABSTRACT:
A device for facilitating the placement of particulate solids into voids. In particular, the device allows boreholes to be filled with a particulate solid material with a reduction in the amount of turbulence thereby allowing the achieving of the proper density for the particulate material. The device includes an improved mantle mounted adjacent the outlet end of the particulate material supply tube for separating the particulate solid material from liquids and gases. The mantle has a perforated portion in contact with the supply tube and a solid portion in contact with the borehole.
