Powdered Coal Injection Machine and Coal Pulverizer Grinding Machine for Sawdust Rotary Dryer

Brief Introduction of Powdered Coal Injection Machine

Coal injection machine is used for crushing the lump coal to some certain particle size and further grinding,finally will 

get the pulverized coal after grinding, which is the important auxiliary equipment for the furnace using the pulverized 

coal as fuel. Coal grinding process is the process of coal being crushed and increased the surface area. 

To increase new surface area, must overcome the binding force among the solid molecules,thus need to 

consume energy. 

Coal injectionmachine researched and developed by our company can save 30%-40% of the amount of coal than the

traditional stoves.   

Coal Pulverizer Grinding Machine is a new generation hot air furnace, special structure, more than 95% heat effciency, steady high temperature, which has the outstanding advantage are as follows:

1. Uniform heating, special structure, long lifetime, low repair

2. Steady fire, high temperature, temperature of hot air can add up to 1300-1400 degree

3. Sufficient burning fuel, high burning rate be more than 95%

4.Uniform temperature, steady heating, increase 50-70% of rotary drier capacity, save more than 50% 

    of coal compare with others

5. easy to fire and conduct, full automatic

6. suitable for most kinds of coal, such as bituminous coal, lignite and so on.

       7. wide range application: new type rotary dryer, vertical dryer, wind-swept mill, old type rotary dryer
