Finely ground calcium carbonate, milled to 250 mesh — a fast-dissolving calcium source for premix and concentrate.
Ground and screened to a fine 250-mesh powder, this grade of limestone dissolves quickly — suited to premix, feed concentrate and industrial powder applications where particle size needs to be small and consistent.

Coarse-granulated calcium carbonate for layer feed, where slower dissolution supports overnight eggshell calcification.
Mid-grade limestone at 80 mesh, sized between our powder and granular grades.

Feed-grade phosphorus and calcium supplement, granular form for even mixing.
