Abstract
We disclose an apparatus (2) for supplying a particulate material (4) at a target mass flow rate, the apparatus comprising an entrainment region (6) configured to entrain the particulate material (4) in a gas or gas mixture flowing through the entrainment region (6), a cross-sectional area of at least a part of the entrainment region being adjustable based on the particulate material (4) and a supply device (8) configured to supply the particulate material (4) to the entrainment region (6) at approximately or at the target mass flow rate.
Claims22
An agitating device for moving a particulate material in a container, the device comprising:
- a first spiral or helical portion;
- and
- a second spiral or helical portion configured to surround the first spiral or helical portion, wherein the first spiral or helical portion is configured to move at least a portion of the particulate material in the container in a first direction and the second spiral or helical portion is configured to move at least a portion of the particulate in the container in a second direction, the first and second directions being parallel to a longitudinal axis of the agitating device and the first direction being opposite to the second direction.
A helical or spiral member for moving a particulate material, the helical or spiral member comprising:
- a plurality of crest portions, wherein the helical or spiral member is configured such that each crest portion extends between a central axis and an outer edge of the helical or spiral member, wherein a distance between adjacent crest portions of the plurality of crest portions and a shape of at least a portion of the helical or spiral member is selected based on the particulate material.
