Automatic Soil Compactor


TS-0650 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 from the required height into the soil within 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, 305 mm, 450 mm and 457 mm. The rammer is circular faced and is interchangeable for 50 mm or 50.8 mm diameters. Rammer weight is also adjustable to 2.5 kg or 4.5 kg according to reference standard. When compacting 100 mm diameter specimens, the unit operates on a single radius. When compacting 150 mm diameter specimens, the unit operates on the inner and outer radius to obtain even compaction.

The number of blows per layer can be set at the beginning of the compaction process via the digital counter according to the standard preferred by 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 is also available.

Compactor is equipped with programmable digital counter which allows the machine:

  • To select reference standard (number of blows and mould size) by the operator at the beginning of the test
  • To set desired compaction cycle (number of blows and count of the number of inner and outer drops) by user

The Automatic Soil Compactor is supplied complete with:

  • ASTM/EN/BS Rammer
  • ASTM Rammer Face, Ø 50.8 mm
  • EN/BS Rammer Face, Ø 50 mm
