Designed to compact Proctor and CBR specimens, it ensures an extremely uniform compaction degree, granting reliable and repeatable test results.
The Automatic Soils Compactor is supplied with interchangeable rammer feet and has two stroke lengths which means that it can be used to carry out all normal compaction operations required in soil testing laboratories.
It is capable of both light and heavy compaction using either 101 mm or 152 mm diameter compaction moulds. The height of drop of the 2 inch (50.8 mm) rammer can be set either at 12 inches (305 mm) or 18 inches (457 mm) as per requirements. When using the 101mm diameter mould the rammer carriage is locked in one position and the total area of the mould is compacted in about 25 strokes. The Number of strokes can be programmed through the thumb wheel switches with digital display. A selector switch is provided on the control panel for selection between 101 mm or 152 mm diameter mould. For 152 mm diameter moulds the rammer carriage shifts radically by 25 mm to give out 8 blows within the diameter of 101mm and 17 blows between 101mm and 152mm diameter. This sequence is repeated till the rammer completes 56 blows and the machine automatically stops.
