Universal Automatic Compactor

Central Scientific Instruments offers Universal Automatic Compactor. It is a motor driven mechanical compactor useful for soil compaction into 100mm or 150mm diameter moulds. Two sets of rammers are provided one of 2.6kg and the other of 4.89kg are arranged for drop of 310mm and 450mm drop respectively. The rammer assembly is provided with a ratchet and pawl arrangement to lift it from the top of the soil layer. When the rammer reaches the required height, the pawl releases the rammer allowing to fall under its own weight. The release mechanism is operated by an arm moving up and down which is connected to a reduction gear coupled to the motor through another arm. The base plate of the specimen has to be fitted to the rotating base plate of the instrument, which makes 1/5th revolution per stroke. The number of strokes required for the arm can be set on an automatic blow counter. The equipment is suitable for operation on 230V, 50 cycles, single phase, AC supply.
