we can make the crushed grain size as customer need, 
there is different analysis
Uses
Dolomite is used as 
*- an ornamental stone, 
*- a concrete aggregate, 
*- a source of magnesium oxide and in the Pidgeon process 
*- for the production of magnesium. 
*- It is an important petroleum reservoir rock, 
*- a flux for the smelting of iron and steel. 
*- Large quantities of processed dolomite are used in the production of float glass. 
*- production of frit for glaze. 
*- added to soils and soilless potting mixes to lower their acidity and as a magnesium source. 
**- the substrate in marine (saltwater) aquariums to help buffer changes in pH of the water. 
**- one of the basic raw materials in the manufacture of flat glass, which are added by *2% as magnesium oxide helps add to the speed of the glass melting process. 
**- in the manufacture of refractories due to the high melting temperature to ***0 ° C and therefore is used in the ovens foundries in Tlies containers. 
**- used in the steel industry as well as used in furnaces making steel oxygen and furnaces arcs electric  
**- is also used in furnaces smelting to reduce the melting temperature of slag
