Ceramic liner coal hopper feeder

 

Coal hopper feeder is the main equipment of the boiler pulverized-coal system in coal power plant , With the function of continuous and symmetrical conveying of coal to the coal miller according to the required output. It is also applicable to Coal, Metallurgy, and Chemical industries as feeding materials equipment. Usually ,the coal feeder are generally suffering serious abrasion and strong impact.

 

According to the abrasion ,impact and temperature, we select suitable abrasion resistant 

ceramic lining/liner to install on the inner wall of the equipment, like the coal feeder ,coal hopper ,

material silo, So that the equipments can prolong the lifetime at least 6 times than before.

.

 

Applied industry:

The abrasion&impact resistant ceramic liner coal hopper feeder are widely used in the cement ,steel ,chemical ,mining milling,smelting,port ,coal fired thermal power plant .

 

The alumina ceramic lining coal hopper feeder are a ideal wearresistance material for delivering the coal,sand,mine,slag ,ash ,dregs in Pneumatic ,hydraulic material handling and feeding system.

 

Advantages:

 

1. Superior wear resistance

2. Chemical and impact resistance

3. Erosion, acid, alkali resistance

4.Smooth inner wall

5. Easy installation

6. Longer service lifetime

7. Competitive and reasonable price

8.Saved maintenance time and expenditures
