ABSTRACT:
A device for testing the quality of foundry green sand is described including a delivery structure with an invertible riddle, a testing structure with a compaction plunger, and sensors for measuring the compaction and moisture content of the sample, another testing structure with a sensor for measuring the green compressive strength of the sample, and a specimen tube mounted on carriage which traverses between delivery and testing structures. A strike off device 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 strike off device cleans the raised floor. A control panel activates and coordinates the operation of the device. A data processor analyzes the information yielded by the testing apparatus and automatically initiates the correct addition of any additives as needed.
