  • Apparatus for processing materials which are difficult to expand with gas and/or liquid, in an expanded layer
    Patent number: 4306815
    Abstract: Fluid bed processing of products not having suitable properties for fluidization, where gas expansion is not successful. The combined influence of gas expansion and mechanical mixing in the geometry of a horizontally located cylindrical grate enables more economical treating and use of lower gas velocity. The close control of particle residence time gives high quality of final products and extremely homogeneous results. The concentration of more processes into one apparatus is the further advantage of the invention.
