GRID SIEVES AZA0972
The AZA0972 Grid Sieves are heavy-duty screening tools designed for rapid particle size classification of coarse soils and aggregates. These sieves are ideal for quick, visual separation of gravel, crushed stone, and coarse sands in civil engineering, geotechnical, and construction materials laboratories. Their rugged construction makes them suitable for both laboratory and field applications.
Key Features
-
Designed for fast classification of coarse particles
-
Suitable for soil and aggregate testing
-
Heavy-duty stainless steel / galvanized steel construction
-
Precision-welded square or rectangular grid openings
-
Corrosion-resistant, abrasion-resistant long life design
-
Compatible with standard manual and mechanical sieve shakers
Description
Working Principle
AZA0972 Grid Sieves use rigid metal grids with large, uniformly spaced openings. When a test sample is poured onto the sieve, particles larger than the grid openings are retained, while smaller particles pass through. This allows rapid, approximate gradation before detailed laboratory sieve analysis.
Applications
-
Soil mechanics laboratories for coarse soil classification
-
Aggregate grading in construction and asphalt plants
-
Geotechnical field investigations
-
Road, embankment, and earthwork quality control
-
Educational and training laboratories
