Plant for the heat treatment of a pulverulent, granular or similar particulate material

摘要

The invention relates to the chemical industry. The plant forming the subject of the invention is characterised especially in that, in the lower surface of each section 5 of the body 2, two hollows 8, 9 are provided which are arranged on both sides of the overspill opening 7 and one of which, 8, is situated in the neighbourhood of the overspill opening 7 and is in communication with the working space 7' of the body 2 via a slit-shaped orifice arranged along the whole length of the overspill opening 7, while the other hollow 9 is connected to a compressed gas delivery channel 13, each section 5 being provided with a group of vertical emergent orifices 12 produced in the body of the section 5 and connecting the hollow 9 of a section 5 to the hollow 8 of the underlying neighbouring section 5. It is particularly advantageous to employ the present invention especially for the production of catalysts in the chemical industry. <IMAGE>
