Limestone Chips & Grit

Mechanically screened calcium carbonate chips and coarse grit supplied for poultry layers, livestock feed blends, terrazzo flooring, asphalt aggregates, and chemical fluxing.

Available Forms in this Mineral:

Powder & Micronized Limestone Chips & Grit Limestone Lumps

Product Overview

Limestone chips are produced by crushing selected natural limestone lumps and screening them across multi-deck vibrating sieves to remove both oversized rocks and fine sub-sieve dust.

In animal feed, coarse limestone grit is consumed by layer birds to aid mechanical digestion in the gizzard while slowly dissolving in the digestive tract to provide a steady release of ionic calcium during nocturnal eggshell synthesis. In civil construction, it provides sound mechanical interlocking in terrazzo and road asphalt.

Typical Industrial Applications

  • Poultry & Bird Grit: Essential dietary calcium for layer birds and broilers to support strong skeletal structure and eggshell thickness. (Learn more)
  • Terrazzo & Cement Flooring: Economical angular aggregate for precast mosaic tiles and exposed aggregate concrete. (Learn more)
  • Asphalt Pavements: Mineral aggregate and chip seal fraction improving frictional macro-texture on road surfaces.
  • Water Treatment: Coarse alkaline filter bed material neutralizing acidic raw water streams.
  • Chemical & Metallurgical Flux: Sized feed for cupolas and smelting kilns where coarse carbonate is required.

Frequently Asked Questions

What sizes of limestone grit are best for poultry? expand_more
For poultry layer feeds, 2–4 mm and 3–5 mm grit sizes are commonly preferred as they remain in the gizzard longer, releasing calcium gradually during the dark eggshell calcification cycle.
How is dust separated from limestone chips? expand_more
The material undergoes screening on vibrating decks with bottom fines discharge to minimize fine powder content, ensuring clean, uniform stones.
What packaging formats are supported? expand_more
Standard supplies are in 50 kg HDPE woven bags or 1 MT heavy-duty jumbo bags (FIBC). Loose bulk tippers can be arranged for nearby industrial sites.
Can custom size fractions be screened? expand_more
Yes, screen decks can be adjusted at our plant to match specific millimeter apertures requested on your purchase order.
