ABSTRACT:
Coking coal is pounded into a compacted cake of substantially uniform density in a pounding box by means of a plurality of punners mounted on carriages which can move to-and-fro lengthwise of the box. The punners are alternately raised and then allowed to drop under the influence of gravity onto the coal in the box. The raising and dropping is so timed that at any time preferably the foot of only one punner per carriage is in contact with the coal in the box, so as to leave as much as possible of the coal surface area exposed.
