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.
Coal is an organic rock (as opposed to most other rocks in the earth's crust, such as clays and sandstone, which are inorganic); it contains mostly carbon (C), but it also has hydrogen (H), oxygen (O), sulfur (S) and nitrogen (N), as well as some inorganic constituents (minerals) and water (H2O).
Coal is Australia's second biggest export earner, and a huge employer in regional areas. Burning it is also about the very worst thing we can do for our atmosphere.

By 1850, at the apogee of its power, Britain had 1.8% of world population. The area of the British Isles is only about 0.16% of the world land mass. Yet Britain then produced two-thirds of world output of coal and one half of world production of cotton textiles and iron. Output per worker was higher in Britain than in any other country.
We have been collecting coal stocks or inventory data and establishing sampling sites for a long time. Our sampling system now covers not only coal mines, but also transfer areas (e.g. distribution centers and loading/unloading ports) and end users (e.g. power plants and steel mills).
