blast furnace crushing

Unasylva

High compression strength is desirable in order to avoid crushing in the furnace which reduces the possible working height of blast furnaces as well as the specific production per unit of volume. Most metallurgical charcoal produced in the Northern Hemisphere has been of low density, produced from softwoods or from medium-density hardwoods.
