Abstract:
1. An apparatus for mixing at least two solid materials in the form of free flowing particles to form a homogenous mixture, the apparatus comprising: a first discharge hopper for discharging a first material; at least one second discharge hopper for discharging at least one second material; a main funnel having an inner surface and positioned relative to the first discharge hopper and to the at least one second discharge hopper such that in use substantially all of the first discharged material directly impacts the inner surface of the main funnel within a first predetermined distance from a central axis of the main funnel and such that in use substantially all of the at the least one second discharged material directly impacts the inner surface of the main funnel within a second predetermined distance from the central axis of the main funnel and whereby the first discharged material and the second discharged material bounce off the inner wall of the main funnel and mix at the center point axis of the main funnel; and wherein the volume percentage of the first and second materials in the mixture is substantially controlled by the flow area of the discharge from the first and second discharge hoppers.
