The present invention relates to a process for the production of a powder coating, in which a suspension of powder particles is sprayed and the spray jet is directed onto the substrate to be coated, characterized in that

Process for the production of a powder coating, apparatus for carrying

A method and apparatus for pneumatically conveying material in form of granular solids or the like includes a feeder sending the material under pressure and addition of carrier gas in a transport pipe such that its cross sectional area is only partly filled with the material. The transport pipe is subdivided by vibration compensators into several pipe sections of a length of up to several meters which are subjected to vibrations so that the wall friction between the material and the transport pipe is reduced in such a manner that at a flow pattern similar to a strand/crown flow up to a plug flow the carrier gas is charged with material to a high degree and a material layer forming at the pipe bottom is also conveyed. The pipe sections may be made of a rigid vibrating material or may be made in form of a flexible hose which is mounted on a support and either directly or indirectly subjected to vibrations.

Method of and apparatus for pneumatically conveying granular solids

Solid material which is carried out of a fluidized bed reactor with the gas discharged therefrom and which is separated off in a separator is returned to the reactor by way of a recycling means. To reduce problems caused by virtue of differing pressure levels within the system in the recycling operation, the pressure in the recycling means between the separator and the upper boundary of a bed of solid material which is formed in the recycling means is reduced by suction removal of gas to a pressure level which is no higher than or even lower than the lowest pressure in the separator which in turn is lower than the pressure in the reactor.
