Industrial Powder Ball Mill, Energy Saving Coal Slag Ball Grinding Mill 300tpd
Coal mills are used to grind and dry raw coal into fine powder, which is then used to burn in the boiler to generate heat. There are two main types of coal mills: pulverizer and raw coal mills.
Raw Coal Mill
Raw coal mills work by crushing the raw coal into small particles and then drying it in a hot air fan. The dried coal powder is then transported to the combustion chamber where it is burned to generate heat. The process of generating heat from raw coal is similar to that of pulverizer coal mills.
The main structure of coal ball mill includes the feeding part, discharging part and driving part. The main bearing is made of cast steel, and the rotating large gear is processed by casting hobbing. There are liner plates on the inner cylinder wall, with good wear resistance, and the liner can be replaced as needed.
1. Raw coal enters the coal ball mill through the feeding device. At this time, hot air with a temperature up to 300ºC enters the coal mill barrel from the intake pipe.
2. The raw coal falls on the lifting plate of the drying chamber and is continuously raised.
In the process of heat exchange between raw coal and hot air, water is continuously evaporated.
3. After the completion of the drying, the coal pieces are sent to the grinding chamber, and the grinding chamber is rotated to bring up the grinding media steel balls and throw them off.
4. After being ground for a period of time, the coal is turned into a powdery material, which goes into the separator.
After being classified by the separator, the coal powder with qualified fineness enters the coal powder warehouse, while the coal powder with unqualified fineness is re-fed into the coal mill for regrinding until the fineness reaches the standard.
