Abstract

Apparatus (1) comprises a trough(2) with two rotatably arranged shafts (3) extending alongside each other, which shafts (3) are each provided with paddles (7) spaced apart in axial direction with an intermediate distance. The paddles (7) extend substantially in a radial plane with respect to the shafts (3) and extend in circumferential direction over at least a part of the circumference. In circumferential direction, the paddles (7) are at least partly wedge-shaped. Upon opposite rotation of the shafts (3), successive paddles (7) mesh alternately, thereby forming a gap narrowing again and again. Per shaft (3), successive paddles (7) in axial direction are staggered relative to each other in circumferential direction through an angle.

Description

technical field

[0001] The present invention relates to a device comprising a trough having two rotatably arranged shafts extending side by side, each shaft being provided with blades axially spaced at a moderate distance, the blades extending substantially radially relative to the shaft. Extending planarly, extending circumferentially over at least a portion of the circumference, and being at least partially wedge-shaped circumferentially, successive vanes in the axial direction alternately engage as the shaft counter-rotates, thereby forming repeatedly narrowing gaps , the gap has no axial pitch. Background technique

[0002] Such devices are generally known. One structure is described, for example, in JP 58117954 in the name of Nara Machinery Company Ltd. In this device, since there is no axial pitch in the gap, the product is mixed approximately radially when substantially no force is applied axially. The conveying in the axial direction is not carried out by the vane...
