Principle: The sand to be tested is placed into the specimen tube or a core box of the required shape and compacted by a weight. This is achieved by dropping a known weight from a fixed distance, and using the energy produced to compact the sand. Ram with three drops of the sliding weight by turning the cam handle three revolutions. There is two measurement scales on the stem of the machine.One scale is for measuring the compactability and another for the final specimen height. The machine includes stripping post, rammer plunger head, precision specimen tube, transverse core box, tensile co Size:650x350x250mm Weight:30kgs
