Active Lime Production Line
200tpd Quicklime Production Plant Complete Plants
Introduction
Active lime production line refers to the whole process of active lime production. Our production process adopt the rotary kiln with the vertical preheater and vertical cooler for the limestone calcination to achieve the production requirements of energy saving, environmental protection, the high activity. We can provide technological solutions and complete production equipment for 50-1200TPD quicklime (active lime) production line.
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.

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.
The Pilot Production Line of Henan Zhengzhou Mining Machinery Co., Ltd can imitate industrial production to calcinate dolomite materials. The specific operation is to crush the dolomite sample used in the calcination test with a particle size between 10mm-20mm and put it into a rotary kiln for calcination to control different calcination temperatures. The materials were calcined at 950 ℃, 1050 ℃, 1150 ℃, 1250 ℃, and then the materials calcined at different temperatures were collected to detect the loss on ignition, and the main chemical components were detected by X-ray fluorescence spectrometer and X-ray fluorescence spectrometer.
