Abstract
A vertical set of sieves receives the particulate material from a vibrating trough conveyor above the set and is vibrated by an agitator on the machine frame. The sieves are spread apart and then tilted to dump the collected particles into respective funnels. The set can then be swung back and contracted for the the next stage. The funnels are connected to collectors which are automatically weighted.
