SBM Solution On Dolomite Powder Production

What Is Dolomite

Dolomite is a carbonate mineral, including iron dolomite and manganese dolomite. Its crystal structure is like calcite, often rhombohedral. Bubbles will slowly appear when exposed to cold dilute hydrochloric acid. Some dolomites emit orange-red light under cathode ray irradiation. Dolomite is the main mineral component of dolomite and dolomitic limestone. Dolomite crystals belong to the carbonate minerals of the trigonal crystal system. The pure ones are white; gray when containing iron; brown after weathering, with glassy luster, and are the main minerals that make up the dolomite.

Uses Of Dolomite

Dolomite can be used in building materials, ceramics, glass and refractory materials, chemical industry, agriculture, environmental protection, energy saving and other fields. It is mainly used as a flux for alkaline refractory materials and blast furnace ironmaking; production of calcium magnesium phosphate fertilizer and preparation of magnesium sulfate; and ingredients for the production of glass and ceramics. In other applications, it can be used as a flux in the glaze.

Mill Recommendation

Coarse powder( 30-400 mesh) Fine powder (600-2000 mesh)
Vertical mill or Raymond mill  Super fine mill

Remarks: Choose different types of hosts according to the output and fineness requirements.

The First Stage: The Crushing Of Raw Materials

The large dolomite material is crushed by the crusher to the fineness (15mm-50mm) that can enter the mill.

The Second Stage: Milling

The crushed dolomite pieces are sent to the storage hopper by the elevator, and then sent to the grinding chamber of the mill evenly and quantitatively by the feeder for grinding.

The Third Stage: Classification

The ground material is classified by the classification system, and the unqualified powder is classified by the classifier and returned to the main engine for re-grinding.

The Fourth Stage: The Collection Of Finished Products

The powder that meets the fineness is separated and collected in the dust collector through the pipeline through the airflow. The collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then is packaged by a powder tanker or an automatic baler.
