Description

Construction & Working Principle

The AZA0980A consists of a top feed hopper and multiple precision-machined riffle chutes arranged alternately. When material is poured through the hopper, it is evenly divided through the chutes into two equal and representative samples, collected in the pans below.

This method is internationally recognized as one of the most reliable techniques for sample reduction.

Applications

Fine and coarse aggregate sample preparation
Soil mechanics and geotechnical testing
Cement and powder sample division
Mining and mineral processing labs
Quality control in construction projects
