Figure 4 compares a conventional vertical table type pulverizer with a ball tube mill pulverizing system with crusher dryer. The table type pulverizer allows high temperature air to reach the coal charge. The ball mill system with crusher dryer normally reduces the inlet temperature to less than the auto ignition point of the coal charge.

Arsenic in coal a review ScienceDirect. The ash of the Silesian bituminous coal contained 0.050.01% As (500100 ppm) and the ash of low-ash coal from Newcastle (England) contained 0.8% As 2 O 5 (8000 ppm). Arsenic was found in lithotypes of the Silesian coals (durain and bright clarain) and up to 0.05% (500 ppm) in the ash of the forest bedding.
