FIELD: transport.
SUBSTANCE: invention refers to the area of pneumatic transport of powdered hard material. Plant is designed for the continuous feed of powder hard material from the service tank (10) into the pneumatic transport pipeline (12, 12'). This plant contains the first (14) and the second (16) intermediate tanks installed near each other. The first intermediate tank (14) is built in the form of sluice tank with the upper sluice valve (18) and the lower sluice valve (20). The second intermediate tank (16) is built in the form of injection tank. Between the lower sluice valve (20) of the first intermediate tank (14) and the upper inlet (30) of the second intermediate tank (16) the system (50) of intermediate pneumatic transport is located to transmit the powdered hard material from the first intermediate tank (14) into the second intermediate tank (16). System (50) is provided with the device for material fluidisation.
EFFECT: provides simplification of construction.
