An apparatus is proposed for separation of dry granular mixture into fractions with different content of particles of high density, where the spatial inhomogeneity of the concentration of dense particles in the volume of the mixture is created by rotating the dry granular mixture inside the channel curved along the spiral.

It is provided a method of converting a carbonaceous material into syngas at a carbon conversion rate of at least 78% comprising gasifying the carbonaceous material in a fluidized bed reactor producing a crude syngas, classifying the crude syngas by particle size and density into a cut sizing device, introducing the classified particle crude syngas into a thermal reformer and reforming the classified crude syngas at a temperature above mineral melting point, producing the syngas.
