ZL-2427 Soil Shrinkage Test Apparatus

Equipment description：
Apparatus is used to test moisture content of contracting limit after the specimen lost moisture, linear contracting rate, body contracting and contracting coefficient. 

The instrument consists of the main part and the quasi-soil part  

 1, the main part of the floor, table pole folder table, plate and other components.
 2.Head composed of quasi-soil part of the guide ring, ring knives, ring orientation, prospective soil
   

Function Principle

Smear Vaseline in the ring knife. Soil samples introduced from the ring knife, and immediately weighed, set the sample in a perforated plate into the instrument, well weighed, a note of the early readings in the 20 read ° C for shrinkage test (can be equipped with ten thousandth of one kilogram scales). And then, based on soil test procedures (SDS.01-79) operating to the scale reading is essentially the same date, the R & D unit of Hebei Province, Hongyu Instrument Equipment Co., Ltd. Phone 0317-4406818 then soil samples in 100 - 105 ° C temperature drying to constant weight, saying the soil is heavy. Scale from the two vertical four positions in the horizontal and vertical measurement first, then computing.

After using Soil shrinkage instrument     

The instrument should be to wipe clean, coated with a thin layer of grease to prevent rust
