ABSTRACT:
A device for testing the compactibility of a sample of granular material is described including a delivery structure with an invertible riddle, a testing structure with a plunger to compress the sample and an encoder to measure the compactibility of the sample, and a specimen tube mounted on a carriage which traverses between the delivery and testing structures. A wiper levels the sample within the specimen tube. The floor of the specimen tube can be raised to eject the sample after testing and the same wiper cleans the raised floor. A control panel activates and coordinates the operation of the device.
