Raymond mill is mainly composed of main unit, analyzer, fan, dischargeing cyclone separator, powder cyclone separator and air duct. Among them, the main unit consists of frame, blow shell, shovel, grinding roller and grinding ring. Working principle of Raymond mill The rollers tightly rolled on the ring under the effect of centrifugal force.
In ironmaking, limestone and dolomite are used in the production of sinter, pellets, and directly in blast furnace as fluxing materials. In case of steelmaking limestone and dolomite are used as lime or calcined dolomite both in the primary steelmaking (basic oxygen furnace, electric arc furnace), and in the secondary steel making processes.

Working principle of Dolomite powder raymond roller mill The rollers tightly rolled on the ring under the effect of centrifugal force. Shovel sends material between the roller and ring and the material is grinded into powder under the high pressure.Then the fan blows the power up into the analyzer.
results reflected the effect of this joint opening. Nicholls and Duvall Q]) studied the effect a charge diameter has on explosive performance. A recent study {14) showed horizontal bedding without or with conspicuous jointing, folds, faults, caves, and filled joints influence blasting and mining in lime stone and dolomite quarries.
La 2 O 3 on dolomite surface occupies active sites, so carbon filaments are not suitable for accumulation and carbon deposition is inhibited. Carbonate (La 2 O 2 CO 3 ) in the catalyst can react with carbon to slow down the carbon deposition on the surface and improve the activity and service life of the catalyst.
