JDM - 1 type electromotive relative density spectrometer
This instrument applies to particle diameter less than 5mm without sexual soil particle, and condensed in 2-5mm sample parts quality is not more than 15% of total quality sample parts to determine the minimum and maximum density soil porosity ratio, used to calculate the relative density. This instrument mainly by motor and sprocket driving mechanism composition. A group of sprocket driven compaction hammer does vertical TuShiYang pieces, another group of driving vibration fork round-trip vibration strike soils around to obtain sample parts maximal density and relative density.
Its main technical indices:
1. The specimen mould: 250ml, the diameter: Ø 5cm, height: 1.27 cm, attach liners
2. Hammer: Hammer quality: 125 Kg, every minute strike 32 times
Hammer diameter: Ø 5cm
3. Hammer falls high: 15cm
4. Timing range: 0 - earlier
5. Power: 120W
6. Power: 220V 50Hz
