A distribution apparatus (1) for distributing sliding solid material, comprising:
- at least one first collector (10) comprising a first plurality of first ports (11) for the passage of sliding solid material which can be connected to one or more departure stations (12) for the sliding solid material and a first plurality of inlet pipes (13) for transporting sliding solid material,
- at least one second collector (20) comprising a second plurality of second ports (21) for the passage of sliding solid material which can be connected to one or more arrival stations (22) for the sliding solid material and a second plurality of outlet pipes (23) for transporting sliding solid material,
- at least one central connection (30) which is interposed between the first collector (10) and the second collector (20) and which has a first opening (31) which is directed towards the first collector (10) and a second opening (32) which is directed towards the second collector (20),
- wherein each of the first ports (11) is connected to a respective inlet pipe (13) which is provided to transport the sliding solid material from the first collector (10) to the central connection (30), and each of the second ports (21) is connected to a respective outlet pipe (23) which is provided to transport the sliding solid material from the central connection (30) to the second collector (20), wherein each of the inlet pipes (13) is controllable in terms of movement between an operating position, in which the inlet pipe (13) is connected with a first opening (131) thereof to the first port (11) and with a second opening (132) thereof to the first opening (31) of the central connection (30), and a rest position, in which the inlet pipe (13) is connected with the first port (11) and the second opening (132) is disconnected from the first opening (31) of the central connection (30), by means of rotation of at least one portion of the inlet pipe (13) including the second opening (132) and/or
- wherein each of the outlet pipes (23) is controllable in terms of movement between an operating position, in which the outlet pipe (23) is connected with a first opening (231) thereof to the second opening (32) of the central connection (30) and with a second opening (232) thereof to the second port (21), and a rest position, in which the outlet pipe (23) is connected with the second port (21) and the first opening (231) of the outlet pipe (23) is disconnected from the second opening (32) of the central connection (30), by means of rotation of at least one portion of the outlet pipe (23) including the first opening (231).
