Apparatus for transferring solid particles to a receptacle comprises a primary loading tube (2) containing at its lower end an annular gas supply chamber (3) coaxially aligned within it. The innermost surface of the annular chamber (3) forms a secondary loading tube (6) which has a Coanda surface (12) at its lower end. A slot (11) is provided between the innermost surface of the gas supply chamber (3) and the Coanda surface (12) to form a Coanda nozzle. The apparatus is particularly suitable for use in loading catalyst to a reactor and achieving a high packing density with a low voidage. In use, particles falling near the center of the primary loading tube are entrained and separated by gas emerging from the Coanda nozzle and have a high velocity imparted to them. |
