Abstract:
A device for spreading particulate materials, comprising:a source of pressurized gas; a chamber having first and second substantially oppositely positioned ends, the chamber coupled to the source of pressurized gas; at least one material hopper coupled to the chamber, the at least one hopper having at least one opening releasing particulate materials into the chamber via gravity; and a flexible exit conduit coupled to the chamber, the flexible exit conduit accepting pressurized gas and particulate materials from the chamber, wherein the pressurized gas from the source of pressurized gas enters the chamber at a point below said at least one hopper opening such that the distance between the first end of the chamber and entrance point of the pressurized gas into the chamber is between about one-half and about three-quarters of the distance from the first end to the second end of the chamber, such that when particulate material is deposited into the chamber, the particulate material is entrained through the exit conduit by the pressurized gas.
