Abstract: | The goal of the inclined conveyor method for particle shape separation is to process a large amount of feed material for
recycling technology. The high feed rate has been achieved because the movement of particles is faster than for other previously
introduced equipment. The separation performance of the apparatus was tested with foundry sand. A large amount of sand was
treated, and various processing capacities were studied experimentally. The feed method was improved from point to line with
wide troughs to process the higher feed rate. We succeeded in attaining a feed rate of 1.49 × 10−3 kg/s with a 0.3-m trough. The space filling, which was an important factor in deciding the capacity of the feed rate, was
defined. This method is useful for any kind of line-feed method.
