coal comes from plants, and plants get their energy from the sun, the energy in coal also came from the sun. Th e coal we use today took millions of years to form. We can't make more in a short time. Th at is why coal is called nonrenewable. 300 million years ago Before the dinosaurs, many giant plants died in swamps. 100 million years ago

The Gebr. Pfeiffer coal mills are designed in such a way that no variable speed drive of the mill is necessary, thus reducing the investment costs, as no frequency converter is required when changing over from coal to pet coke. The commissioning of the mill is planned before the rainy season in 2022.

De-dusting bag filters needs to be installed at the top to vent air when material is fed to a hopper. Mill Feeders: Feeders for coal mill are generally installed directly under hoppers with rod gate in between. The feeders are generally 2 to 3 m long and discharge on to conveyor or feeding chute to mill.

To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.

Coal, lignite or petcoke are ground in the Pfeiffer vertical mill by using hot gases from a hot gas generator. The grinding plant can be inerted. The raw coal is dried while being ground in the mill even if feed moisture exceeds 25%. The feed size that can be handled is up to 100 mm, making two-step pre-crushing unnecessary.
