A HO scale model train layout plan, with Faller car system roadways. The layout is 9 ft X 25 inches pretty small for a HO layout and should fit in any average household. The whole layout is broken down in 3 equal sections of 36 inches X 25 inches, plus you would need a staging zone, possibly with sector plates.

Model equations. The mass of coal to be pulverized depends on the mass flow of the raw coal, wc, the return flow of the particles rejected by the classifier, wret, and the grinding rate which is proportional to the mass of raw coal on the grinding table, mc.
