Dolomite powder production line - rotary kiln calcining dolomite
Re-fired dolomite: Because the calcination temperature is high and the kiln temperature is uniform, the resulting dolomite sand has high purity, high structure density, uniform composition, and hydration resistance is relatively light. It is suitable for the production of dolomite bricks, magnesia-calcium bricks, and amorphous refractory insulation materials with high calcium elements. Calcination temperature 1600-1800℃
Calcination equipment: cement rotary kiln Material: pulverized coal
Crushing (10-38mm) - calcination of cement rotary kiln - screening - finished product
Making dolomite powder: magnesite-picking-crushing-grinding into powder (325-1250 mesh), which can be used for plastics to replace light calcium powder and lithopone.
Iron ore mining - screening - crushing - calcining - crushing - packaging - dolomite powder
Magnesium salt production: Dolomite is calcined-crushed-mixed with hydrochloric acid--separated to obtain magnesium-containing saturated solution and calcium-containing precipitation--saturated solution is used to produce magnesium-containing chemical substances, and the precipitate is reacted with ammonium bicarbonate to produce ammonium sulfate saturated solution and calcium bicarbonate.
Key processing machinery and equipment Dolomite milling is generally divided into dolomite coarse powder processing (0-3MM), stone powder processing (20 mesh-400 mesh), and dolomite ultrafine powder processing (400 mesh-1250 mesh) and silicon micropowder processing. (1250 mesh - 3250 mesh) four types.
