300mm Stone Laboratory Sieve Test 1 PCS

The 300mm Stone Laboratory Sieve is a standard testing tool used for particle size analysis of stone, aggregate, sand, and other granular materials. Material testing laboratories, construction companies, and quality control departments use this sieve to evaluate material grading and ensure compliance with construction specifications. Accurate sieve analysis supports proper mix design, material selection, and long-term structural performance.

Purpose and testing function
This laboratory sieve helps separate particles based on size during sieve analysis. Engineers and technicians rely on this process to assess aggregate suitability for concrete, asphalt, and road construction. When particle size distribution remains within specification, construction materials perform more reliably. Therefore, accurate sieving plays a direct role in construction quality control.

Standard 300mm size advantage
The 300mm diameter provides sufficient surface area for efficient sieving of coarse and fine aggregates. As a result, technicians can spread samples evenly without overloading the sieve. Uniform particle movement during shaking improves separation accuracy and produces consistent test results. This standard size also allows easy comparison of results across different laboratories and projects.

Precision mesh construction
The laboratory sieve uses uniform mesh openings manufactured to precise tolerances. Consequently, particles pass or retain accurately according to size classification. Consistent mesh quality reduces testing variation and improves repeatability. Laboratories depend on this accuracy to maintain confidence in gradation analysis results.

Strong frame and durability
The rigid metal frame maintains its shape during handling, shaking, and cleaning. Because of this strength, the sieve resists deformation during repeated use. Long-term dimensional stability ensures that testing accuracy remains consistent over time. With proper care, the sieve performs reliably through many testing cycles.

Easy cleaning and maintenance
The smooth surface finish allows technicians to clean the sieve quickly after each test. Therefore, residual material does not contaminate future samples. Clean equipment supports accurate testing and improves laboratory efficiency. Regular inspection and cleaning also help protect mesh int
