Eggshell Grinder / grinder

Eggshell Grinder
Eggshell Grinder

Upon closing the lid after putting eggshells in the Eggshell Grinder, the sharp blades inside break eggshells into pieces once you turn the lid with your hand. The eggshell powder can be seen through the lid & net of Eggshell Grinder.
The calcareous and protein components in the eggshell powder can be used as a nutritious fertilizer for plants. Also, eggshell powder can be used to remove old dirt on the surface of bowls and dishes. Eggshell powder can be used as an eco-friendly detergent as well. The alkaline eggshell is a bleaching agent whitening clothes.
Use Eggshell Grinder to turn eggshells into a helpful resource.
