Abstract (en)

[origin: EP0584579A2] In the pressure treatment of granular material in the roller gap (15) of a two-roller machine, air (17) is pressed out of the bulk material and flows, counter to the material flow, through the bulk material and loosens the latter in the process. As a result of a widening of the lower part of the material feed shaft (12), the bulk material can form a slope (16) and is conveyed in a free flow to the roller gap (15), unhindered by the air flowing towards it and by friction against the shaft wall. <IMAGE>
