Product Description
Enverinomental Friendly Horizontal Rotary Kiln Production Of Quicklime
Analysis & Calcination Test of Dolomite
The chemical composition of dolomite is CaMg (CO3) 2, which is a kind of carbonate mineral of the crystal belongs to of trigonal system. Its Mohs hardness is 3.5-4 and the specific gravity is 2.8-2.9. It is not only the main raw material of magnesium production line, but also could be used for the refractory inner layer of the converter, slag making agent, cement raw material, glass flux, kiln industry, fertilizer, stone for construction and decoration, paint, insecticide and medicine, etc.
As the main raw material for silicon-based magnesium smelting in China, the chemical composition of dolomite is very important. Only if each component is correct, it could meet the requirements of silicon thermal smelting. Therefore, the analysis and calcination test of various components of dolomite and forging white in the early stage is particularly important.

Lime rotary kiln is a key equipment of lime calcination production process. It has the characteristics of wide combustion space and thermal field, which can fully burn the fuel, and has a uniform temperature field as a heat exchange device, which can meet the requirements of limestone calcination. And as a reactor can meet the heat, temperature and time requirements of lime formation.
Lime rotary kiln is a vertical preheater rotary kiln. The kiln cylinder is made of high-quality carbon steel plate and the cylinder is on the wheel support device. A large gear ring is fixed in the transmission part of the cylinder, and the cylinder rotation is realized by the frequency conversion speed regulating motor driving the reducer, the pinion gear, and the large gear ring.
