ABSTRACT:
Apparatus for analysis of particulate material employs a stack of spaced sieves permanently joined to form a sieve column. Clean-out ports are provided for inter-sieve spaces. In one embodiment the clean-out ports communicate with a common passage that is closed by a removable rod. In another embodiment individual clean-out ports are closed by separate plugs. Guard sieves are provided to protect the usual sieves at the ends of the column.
