Dolomit

About dolomite

Dolomite is a carbonate rock composed mainly of calcium and magnesium carbonates. It is generally soft to medium-hard and is processed into construction aggregate, industrial mineral feed and mineral powder.

Composition, density and strength vary by deposit. Hardness, abrasiveness, moisture and chemical composition should be confirmed before equipment is selected.

Recommended process

Vibrating feeder → Jaw crusher → Impact crusher → Vibrating screen → Finished fractions

The jaw crusher performs primary crushing of large pieces. The impact crusher reduces the material and improves particle shape, while the screen separates finished fractions and returns oversize in a closed circuit.

A VSI crusher may be added for 0–5 mm manufactured sand or improved shape. Mineral-powder production requires drying where necessary, followed by milling and classification.

Recommended equipment

Vibrating feeder — stable feeding

Jaw crusher — primary crushing

Impact crusher — secondary crushing and shaping

Cone crusher — alternative for harder or more abrasive dolomite

VSI crusher — manufactured-sand production

Vibrating screen — fraction separation

Mill and classifier — mineral-powder production

Belt conveyors — material transfer

Dust collection — control during crushing and milling

Typical products

0–5 mm — manufactured sand and fine material

5–10 mm — fine aggregate

10–20 mm — concrete and asphalt aggregate

20–40 mm — road-base material

Mineral powder — industrial applications

Important selection factors

Confirm maximum feed size, hardness, moisture, clay and fines content, chemical composition, required capacity and finished products. Quartz or other hard inclusions can increase abrasiveness and may change the recommended crusher.
