Environmental desulphurization limestone mill  production line

LM Series Vertical Mill

Feed size：38-55mm
Production Capacity：15t/h

Brief Introduction:

The large industrial limestone mil of Liming Heavy  is mainly used for milling, crushing and screening of limestone, limestone desulphurization aspect of the thermal power and steel companies.

Introduction:

Coordinated with environmental desulfurization equipment manufacturers and R＆D institutions in Japan, Germany, the United States, Finland etc., Henan Liming LM Vertical Mill achieved good export performance, and has been successfully applied to enterprises such as Datang, Yulian, Shendong, Tiantie, Zheng Aluminum, Wuhan andSteel ,Huaneng, China Electric Power etc.

The desulphurization limestone mill process plant of Henan Liming heavy industry is also widely used in the limestone, Quartz, feldspar , calcite and so on.

Features:

1、This production line is a combination of crushing, drying, grinding, and classifying.

2、Low Investment Cost, low Operation Cost

3、Its products have stable chemical composition

4、Simple and reliable operation

5、High Drying Ability,

6、Environment Friendly.

Structure:

The desulphurization limestone mill process plant is consist of Hopper, feeder, Jaw crusher, MTW series Trapezium Mill, powder collector device.

Working Principal:

The vertical mill manufactured by Henan kefid participate in is to add a humidifier to improve the efficiency of desulfurization in the rear of the boiler. The process’s absorbent is limestone powder, limestone powder is injected into the pneumatic chamber 850 to 1150 ℃ temperature zones, limestone thermal decomposition of calcium oxide and carbon dioxide, calcium oxide and the reaction of sulfur dioxide in the flue gas to produce calcium sulfite. When the calcium sulfur ratio control in the 2.0 to 2.5, the system desulfurization rate can reach 65 ~ 80%. Humidifier water, flue gas temperature decreased, the general control of exports of flue gas temperature is higher than dew point temperature 10 ~~ 15 ℃, the humidification water temperature of the smoke heating by rapid evaporation, the unreacted absorbent, the reaction product was dried state with flue gas discharged by the dust collection down.
