Coal powder plant
As a fossil fuel, coal is abundant in the earth and widely distributed. It can be summarized into two major uses according to the purpose of use: thermal coal and coking coal. For example, coal for power generation, steam locomotives, building materials, industrial boilers, metallurgy, and daily life is thermal coal; coking coal is mainly used for coking, and coke is mostly used for steelmaking.
The first stage: Crushing
Large pieces of coal are crushed by the crusher to the feed fineness of the mill ( 80% below 20mm)
The second stage: Milling
The crushed small lump coal is sent to the silo by the hoist, and then sent to our grinding mill chamber for grinding evenly and quantitatively by the vibrating feeder.
For samller capacity, use MTW European Type Grinding Mill because lower investment, for higher capacity , our LM Vertical Roller mill is more suitable because of its automation, safety and higher working efficiency.
The third stage: Grading
The pulverized coal is classified by a classifier, and the unqualified powder is classified by the classifier and returned to the host for re-milling.
The fourth stage: Collecting
Fine powder complies with the fineness with airflow go through the pipe into the dust collector for separation and collection. The finished powder collected by the delivery device is delivered to the finished product bin, and then packed uniformly with the powder tanker or automatic packing machine.
