What is Dolomite


Dolomite is a carbonate mineral, there are iron dolomite and manganese dolomite respectively. Its crystal structure resembles calcite, and it is often rhombohedral. It will slowly bubble when exposed to cold dilute hydrochloric acid. Some dolomite emits orange-red light under cathode ray irradiation. Dolomite is the main mineral component of dolomite and dolomitic limestone. Dolomite crystals belong to the trigonal system of carbonate minerals, which are white when pure; gray when they contain iron; brown after weathering, with vitreous luster, and are the main minerals that make up dolomite.

The use of dolomite

Dolomite can be applied in construction material, ceramic, glass, refractory material, chemical, agriculture, environmental protection and energy saving fields. Dolomite can be used as basic refractory material, blast furnace flux,calcium magnesium phosphate fertilizer, and the material of cement and glass industry.

Dolomite milling process


The composition of dolomite raw materials


Remarks: Often contains impurities such as silicon, aluminum, iron, and titanium.

Dolomite Powder Making Equipment Selection Program

Product fineness(mesh)Fine powder(80-400 mesh)Ultra-fine deep processing(400-1250 mesh)Micro powder(1250-3250 mesh)
ModelRaymond mill,vertical millUltra-fine mill, ultra-fine vertical mill

Stage 1: Crushing of raw materials

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

Stage 2: Grinding

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

Stage 3:Classification

Through classification, the coarse powder will return to main mill to grind again.

Stage 4:Collection of finished products

The powder that meets the fineness enters the dust collector through the pipeline with the air flow for separation and collection, and the collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then is packaged uniformly.
