Geotextile equivalent aperture tester (wet sieve method)

Scope of application:

The equivalent pore diameter of geotextile and its related products was determined by wet screen method. The geotextile sample without tension is used as the screen, and the sample and graded particle material are sprayed with water under the specified vibration frequency and amplitude to make the graded particle material pass through the sample. The effective pore size of the specimen is expressed by the specific particle size of the passing particle material.

Meet the standard:

GB/T17634-2019,ISO/FDIS 12956-1998,etc.

Instrument features:

It is suitable for the determination of effective aperture of various geotextiles.

Split type design is adopted to avoid damage to the control system caused by vibration during high-speed operation;

The parts are connected with aviation plug, easy to disassemble and assemble;

Using mechanical vibrating screen vibration, smooth and efficient;

Fully transparent protective device, can be cleaned to observe the experimental situation

The sample is placed on the metal grid to avoid excessive deformation of the sample due to the quality of the particle material.

Vibration time can be set arbitrarily, digital display time:

Adjustable amplitude, knob adjustment mode, simple operation;

Convenient experiment, simple operation.
