Abstract
The invention provides apparatus for determining and recording characteristics of particulate material in a batch of such material comprising a separator chamber having an inlet, means for reading an identifier on a batch of particulate material supplied to the inlet and providing the identifier as a digital output, means for causing a flow of gas in the separator chamber to separate the particulate material into a first fraction and a second fraction, first counting means, second counting means, means for weighing the first fraction and providing the result as a digital output, and means for integrating the digital outputs and for transferring them to a computer programmed to store data in prescribed format in a database, from which it may be manipulated to afford comparison of characteristics of batches of particulate material.
