Shell-Mix® is manufactured from selected limestone and is screened to meet defined sizing criteria primarily for the poultry industry.


Shell-Mix® is commonly used as an alternative to crushed shell for poultry and is also suitable for other applications where high calcium and consistent product sizing is required.

Shell-Mix® is dedusted below 850um and is available in bulk, 1000kg+ sacks and 25kg paper bags.

Shell-Mix® products are tested regularly to ensure they meet Graymont specifications.


Shell-Mix® is available from our Havelock plant in Nova Scotia, Canada and is broadly distributed to various other locations. Please contact our sales team to discuss application guidelines and dosage rates.

After processing, products derived from limestone can eventually revert to their original chemical form by reacting with carbon dioxide in the atmosphere or from industrial processes.
