When measuring the strength of particulate material, the existing technology widely uses electric heating plate heating technology for sample feeding. The operator needs to manually use tweezers and other tools to clamp the particulate material. The particulate material is transferred from the storage environment to the particle strength determination instrument, and easily absorbs moisture in the air.
