The Asphalt Pavement Fiber Air Jet Sieve Analyzer is a precision laboratory instrument designed for particle size distribution and passing rate testing of cellulose and mineral fibers used in asphalt mixtures. Utilizing air jet sieving technology, it ensures efficient dispersion and accurate analysis of fine fibers and powders that are difficult to test with conventional sieving methods.

Asphalt Fiber Air Jet Sieve Analyzer

Model:TDJT533-A

I. Product Introduction

The Asphalt Pavement Fiber Air Jet Sieve Analyzer is a professional testing instrument designed and manufactured in accordance with the technical requirements for “fiber stabilizers for asphalt pavements” proposed by the Ministry of Transport. It is mainly used for air jet sieving tests of flocculated cellulose fibers and mineral fibers to determine key technical indicators such as particle size distribution and passing rate, thereby ensuring the quality stability and performance of fibers used in asphalt mixtures.

In addition to asphalt pavement fiber testing, this equipment can also be used for analyzing dry powder materials that are difficult to test by conventional sieving methods. It is widely applied in pharmaceutical, food, chemical, and industrial powder fields, making it a versatile air jet sieve analysis instrument.

II. Application Scope
