Abstract
The invention relates to a method and apparatus of forming pellets and in particular spherical binderless pellets from lower rank coals. The method includes the steps of feeding a pelletizing means 10, with a lower rank feedstock, 1; rotating the coal in said pelletizing means, 10, to form pellets in the absence of any binder, wherein the pellets are formed by compaction and layering of coal fines. The moisture content of the lower rank coal is at a level so as to at least substantially fill the voids within the coal.
