Coal pulverizer

Coal is primarily used as a solid fuel to produce electricity and heat through combustion. World coal consumption was about 7.25 billion tonnes in 2010. When coal is used for electricity generation, it is usually pulverized and then combusted (burned) in a furnace with a boiler.
 
CLIRIK coal pulverizer, which is designed by our engineers and technicians on the basis of multiple innovation, test and experience over two decades, has absorbed many advantages of home and abroad mill manufacturing technique. It has been proved by thousands of customers that our machine has outstanding features and stable quality. CLIRIK coal pulverizer can upgrade its production and the additional value which is suitable for our customer to use. It is the ideal equipment for fine milling.
           
Advantages and Features of coal pulverizer:
l、 High efficiency
Under the same finished final size and the same motor power, the capacity of coal pulverizer is twice as much as jet mill, mixing grinder and ball mill.
2、Long lifecycle of spare parts
The ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is 2-3times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate.
3、High safety and reliability
As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.
4、 High fineness and flexible adjustment
The final fineness of the grinding materials can be adjusted between 325 meshes and 3000 meshes, and the product fineness can reach D97≦5um.
5、Environment-friendly
The application of pulse deduster and muffler greatly alleviates dust pollution and noise.
 
How does coal pulverizer work?
1) After crushed by hammer crusher, the large materials become smaller pieces and are sent to the coal pulverizer.
2) When the coal pulverizer is at work, the granulated materials are crushed and grinded by the rollers into particles below 47micron.
3) The high-pressure air blower constantly inhales air within the coal pulverizer.
4) Along with the high speed airflow, micronized materials are brought to the classifier.
5) The qualified particles are screened and driven into the cyclone powder collector, finally exit from the discharging valve at the bottom;
6) A small proportion of the fine powders, with airflow, moving to the dust cleaner. Filtered clean air will be emitted from the air outlet of muffler in the end.
