Dolomite is a carbonate mineral composed of calcium magnesium carbonate CaMg(CO3)2. The term is also used to describe the sedimentary carbonate rock dolostone.

Dolostone or dolomite rock is composed predominantly of the mineral dolomite with a stoichiometric ratio of 50% or greater content of magnesium replacing calcium, often as a result of diagenesis. Limestone that is partially replaced by dolomite is referred to as dolomitic limestone.

Application IndustryApplication Industry

1. Dolomite is chiefly used as refractory, ramming, and fettling material in steel melting shop.
2. As fluxing material in blast furnace operation in secondary steel and ferromanganese manufacture. To a lesser extent it is used in the glass industry especially in sheet-glass manufacture. It also finds use in the manufacture of mineral wool.

Dolomite Processing EquipmentDolomite Processing Equipment

1. Crushing
For dolomite mining and crushing to required fineness, we usually use the Jaw Crusher as the first dolomite crusher equipment and the Impact Crusher or Cone Crusher is usually used as secondary or tertiary dolomite crushing machine. In the whole dolomite crushing line, we use Vibrating Feeder to transport the materials to specified machine. Vibrating Screen machine can separate the finished products.

2. Grinding
Dolomite grinding is usually the last part of dolomite mining process and so this part decides the quality of the final dolomite products. Our dolomite grinding mill includes trapezium grinding mill, vertical mill, high pressure grinding mill, coarse powder mill and ball mill machine.

1. Large Dolomite materials should be fed into the jaw crusher by vibrating feeder through a hopper for primary crushing.
2. After primary crushing, the material will be transferred to impact crusher by belt conveyor for secondary crushing.
3. The crushed dolomite materials will be transferred to vibrating screen for separating. After separating, the parts that can meet standard will be transferred away as final products, while the rest will be returned to impact crusher, thus forming a complete circuit.
4. Size of final products can be combined and graded according to your specific requirement.
