The invention relates to a balance for detecting the mass throughput of bulk goods fed to the inlet 3 of an extruder 1. The balance consists of a weighing container 6 which can be filled batchwise with the bulk goods 14 and a funnel-shaped container 2 arranged underneath it and above the inlet 3 of the extruder 1. The weighing container 6 projects with its lower part into the upper part of the lower container 2, 5, the lower part of the weighing container 6 forming a small annular gap 7 with the upper part 5 of the lower container 2, 5. The weighing container 2 is designed as a cylinder and is closed by a bottom plate 8 fastened to it, with the exception of a lateral axial annular gap 9, via which the bulk goods reach the lower container 2, 5. The radial annular gap 2 between the two containers 2, 5, 6 is at most three times as wide and at least as wide as the axial annular gap 9 of the container 6. <IMAGE>
