Geotextile equivalent aperture tester (dry sieve method)

Scope of application:

The equivalent pore diameter of geotextile and its related products was determined by dry screening method. The geotextile sample is used as the screen cloth, the standard particle material with known diameter is placed on the geotextile above the vibrating screen, and the sieve rate is calculated by weighing the standard particle material weight of ten industrial cloth, and the sample is replaced by the standard particle material with different diameters. The aperture distribution curve of the textile is drawn and the value of 090 is obtained.

Meet the standard:

GB/T14799-2005,ASTM D4751-2004,JTG E50 T1144-2006,SL/T 235-7-2012, etc

Instrument features:

Adopts split type design to avoid damage to the control system caused by vibration during high-speed operation.

Using mechanical vibrating screen vibration, smooth and efficient;

Vibrating screen can carry out shaking and shaking two vibration modes, vibration frequency is stable;

Equipped with locking protection device, strengthen the stability of the fuselage;

It is equipped with an anti-static device to prevent glass beads from gathering on the surface of the sample due to electrostatic action;
