Automatic Mechanical Compactor

The mechanical compactor automatically compacts and rotates the mold after each blow while keeping track of the number of hammer blows and shutting off once a preset number of blows is reached. The start/stop function of the compactor is independent of the counter. The unit can be used to perform standard or modified compaction tests using a 5.5 lb. (2.5kg) hammer with 12" (305mm) height of drop or a 10 lb. (4.5kg) hammer with 18" (457mm) drop. Hammer lift compensates for the height of the drop for soil thickness in the mold during compaction. Hammer weight is concentrated at the foot, allowing free fall of the hammer. Hammer changes are made from in front of the compactor, making maintenance/adjustments easier without moving the machine away from its mounted location.

Soil Cement Compactor Apparatus

The Soil Cement Compactor Apparatus is designed for use with Soil-Cement Molds to prepare compressive-strength specimens for testing. It features a 15lb (6.8kg) falling weight mounted on a 3/4" (19mm) shaft guide, which strikes the top piston of the mold set to achieve dynamic consolidation of the specimen. The compactor’s base includes a locator pin for accurate positioning, ensuring precise centering of the Test Mold Set. The drop height is easily adjustable using a clip on the shaft guide.
