Abstract
Disclosed is a device for sequentially cleaning the screens of a particle size analyzer of the indexing drum type, as each screen moves out of the screening position. The cleaning member is preferably removed from the drum during each screening step. The particles dislodged from the screen being cleaned are returned to the sample being analyzed in a manner which maintains the accuracy of the analysis. In an alternative embodiment, each screen is cleaned during a screening step, at an indexed position other than the screening position.
