HYCQS-1 Air Jet Sieving Analyzer for Asphalt Mixture Fibers

Overview

The addition of fibers to asphalt mixtures can improve the uniformity and stability of the mixture, while enhancing pavement durability. Therefore, accurate evaluation of fiber quality is essential.

This instrument is mainly used for the sieve analysis of fibers used in asphalt mixtures. It adopts a negative-pressure air jet sieving method to determine fiber quality and fully complies with the requirements of the “Air Jet Sieve Analysis Test Method for Fibers” specified in JT/T 533-2020 Fibers for Pavement.

Test Principle

Under negative pressure, air passes through the filtration system and is discharged through a rotating nozzle to disperse and lift the fiber material during the sieving process. The lifted particles collide with the cover plate and become further dispersed, while the negative pressure draws the material toward the standard sieve.

Particles larger than the sieve aperture are retained on the sieve, while particles smaller than the sieve aperture pass through the sieve and are discharged through the designated airflow channel, completing the sieve analysis process.

The air jet generated by the nozzle also helps to clear the sieve openings during operation, ensuring a more efficient sieving process and improving the accuracy and repeatability of test results.

Features

• Industrial touchscreen control for simple and convenient operation.
• Equipped with an independently developed control system, offering two selectable sieving modes to ensure accurate and reliable test results.
• Sieving time can be freely set within the specified range.
• The specially designed rotating nozzle evenly disperses and lifts the agglomerated materials, preventing electrostatic adhesion and particle agglomeration that may affect the accuracy of sieving results.
• The transparent cover allows real-time observation of the sieving process.
• Equipped with a high-quality vacuum system to provide stable negative pressure during the test.
• Compact design with minimal space requirements.
• Multi-purpose design with optional sieves available for testing different materials.
