Grain Flow Testing and Analysis

Grain flow is the plastic deformation of crystallites in metalworking processes like rolling and forging. It is crucial to control grain flow and understand the relationship between stress and grain flow's mechanical properties. Infinita Lab can conduct grain flow testing and analysis in accordance with ISO, ASTM, and other standards as a professional, reliable third-party testing agency.

Overview

Grain Flow Testing and Analysis is a laboratory evaluation used to determine how granular materials such as grains, powders, or bulk solids move and flow under different handling and storage conditions. The test helps identify issues like poor flow, clogging, or uneven discharge during processing.

This analysis is important in industries that handle bulk materials because it helps ensure efficient storage, transport, and processing of grains and powdered materials while preventing problems such as bridging, arching, or segregation.

Scope, Applications, and Benefits

Scope
