Abstract

A sample divider for fine-grained loose material samples contains - arranged symmetrically below one another - a sample delivery pipe, a divider and collecting vessels for sub-samples provided below the divider. The divider is constructed as a divider cone which has distributed over its base surface sample distribution holes to which a plurality of first sub-sample pipes is connected, below which are arranged a collecting funnel, a second divider cone and below that a plurality of second sub-sample pipes which are connected to the collecting vessels. In this way a starting sample quantity can be divided up into a comparatively large number of sub-sample quantities extremely well and reliably with the sample only passing through the sample divider once.
