Contrary to the teachings of U.S. 3,647,718, regarding the use of raw kaolin clay as the sole clay material, the slurry is flocculated, not deflocculated, before spray drying.
Indirect rotary drum heaters can be used to supply a more uniform heating to the contents of a drum dryer, and may also be used where it is desirable not to contact the material being processed with combustion gases so as to avoid contamination of the processed material. Indirect rotary drum dryers, however, are limited in efficiency. It is more difficult to make the gases in the oven flow in counterflow to the material inside the drum, as the gases in the oven or manifold surrounding the rotating drum have a tendency to rise to the top and generally to be churned by the moving drum surface, thus preventing the heating gases from moving in uniform counterflow to the material inside the drum. Further, because the heating takes place through the drum, a significant temperature differential must be maintained between the external gases and the material moving through the drum to cause significant amounts of heat to flow from the gases into the materials, thus the exhaust gases of an indirectly heated drum necessarily carry with them considerable wasted energy.

The sintered ore, coke, and limestone are then poured into the stack where it burns at 1,800 degrees Celsius. Coke burns as a source of heat and, along with oxygen that is shot into the furnace, helps to form the reducing gas carbon monoxide. The limestone mixes with impurities in the iron to form slag. Slag is lighter than molten iron ore, so it rises to the surface and can easily be removed. The hot iron is then poured into molds to produce pig iron or directly prepared for steel production.

The microwave drying is used in a few coal-drying studies [5, 53]. It has some advantages such as the higher heating rates compared to the conventional heating and the more uniform heat supply [5, 60]. The microwave drying directly uses the electricity as the energy source, so it seems so expensive for the LRC drying. However, it can be used by integrating with a conventional drying system due to the advantages of the microwave drying in removing water inside the coal, which is difficult to evaporate with the other drying technologies (Figure 11) .
The non-electronic hearing aid dryers are usually called dehumidifiers and are very inexpensive. They are either disposable or can be reactivated for continued use without the need for electricity, making them great for travel.
