Eggshell Grinder

Brentwood Eggshell, Spice and Coffee Grinder (Item No. CG-162S)

This compact Brentwood grinder quickly turns dried eggshells into fine calcium powder that’s ideal for animal health. Mix the powder with our Omega Booster or oyster shells to create a highly bioavailable calcium supplement that supports strong bones, eggshell quality, and overall wellness in chickens and other animals.

Beyond animal health, the finely ground eggshell powder offers several practical benefits:

• Garden & soil care — Adds natural calcium to correct deficiencies and support stronger plant growth.
• Composting — Speeds up the breakdown of shells so nutrients become available faster.
• Household use — Works as a gentle abrasive cleaner for sinks, cookware, and surfaces, and can help neutralize odors or brighten laundry.

Simply rinse the eggshells, sanitize them (bake or boil), thoroughly dry, then pulse in the Brentwood grinder until you reach a fine, powder-like consistency. Store in an airtight container and use as needed.
