in replying to your message left on this forum, the answer is yes there is a system which can dry raw coal of +40% moisture content. The system itself can transport coal up to 500m vertical and horizontally, as well as drying the material itself. The key is the size of the particle. The finer the particle the better performing our system is.

Abstract: The low rank high moisture coal have a great tendency to drain out moisture from their pores under suitable ambient atmospheric conditions. The influence of rain has a negative impact which needs to be protected all round. Stage processing of coal with time gap confirms an enhanced rate of moisture loss in low rank coal.

Decomposition moisture is produced from the thermal decomposition of organic constituents of coal. Water of hydration of mineral matter is the water that is incorporated into the crystal lattices of the clay and inorganic minerals in coal. The moisture content of coal ranges from 6% by weight in anthracite coals to 45% by weight in lignite.
Get priceThe results demonstrated that inherent moisture in Collie coal had a significant influence on the char yield and reactivity, depending on the pyrolysis conditions. Under slow-heating conditions in the fixed-bed reactor, moisture was swept out of the reactor during the long heating process, leading to little influence on char yield and reactivity.

Moisture Retention • Moisture retention within the freshly placed grout should be extended when the in-place grout is below 50°F. This is important because the rate of hydration is slower at low temperatures. • In order to assure optimum curing below 50°F, leave clean, moist rags on the exposed positions of the fresh grout for 24 h or more.

It's no different - you need to measure wet and dry weight in both cases (to calculate the amount of water that has exited the specimen), it's just the normalising parameter which is different (dry for soil, wet for coal).
