FIELD: material processing.
SUBSTANCE: device for feeding granular material contains an inclined channel. The inclined channel can have an inner area, and the inner area can have an upper third of the inner area, a middle third of the inner area and a lower third of the inner area. The upper third of the inner area is located above the middle third of the inner area, and the middle third of the inner area is located above the lower third of the inner area. The channel additionally forms a hole formed by a wall of the inclined channel. An air movement mechanism can be connected to the channel. It is designed to move air through the hole into the inclined channel in the direction of the axis of the inclined channel, so that more air exits through the lower third of the inner area, rather than through the upper third of the inner area or the middle third of the inner area. According to the first option, an outlet hole for the granular material is located closer to the far end of the inclined channel than the hole formed by the wall of the inclined channel. According to the second option, in the device, when using the above features, the air movement mechanism is made with the possibility of feeding air to the specified hole formed by the wall of the inclined channel at a pressure from approximately 7 kPa (1 psi) to 140 kPa (20 psi).
EFFECT: device facilitates the control of the material distribution.
