Automatic Soil Compactor is designed to compact specimens automatically and uniformly, assuring conformity with the above listed international standards.
The principle of the design is to allow the hammer to drop the required height into the soil in the mould which rotates circularly to distribute the blows uniformly over the surface of the specimen in the mould. The drop height is adjustable to 300 mm, 12” (305 mm), 450 mm and 18” (457 mm). The rammer is circular faced and interchangeable to 50 mm or 2” (50.8 mm).diameter. Rammer weight is adjustable to 5,50 lbs (2.5 kg) or 10 lbs (4.54 kg) according to reference standard. When compacting 100 mm or 4” diameter specimens the unit operates on a single radius and when compacting 150 mm or 6” diameter specimens the unit operates on an inner and outer radius to obtain even compaction.
The number of blows per layer can be set at the beginning of the compaction process by the digital counter according to the standard preferred by the user. This automatic blow pattern ensures effective and equal compaction for each layer of soil by rotating the base table, so the mould, in equal steps and travelling the rammer across the mould. User-defined blow number and in-out distribution are also available.
