Abstract
A massive compacted coal charge body is made by pounding a particulate bed consisting of moist coal particles by a plurality of sequentially operated rams until the particulate bed is converted into a charge body the height of which exceeds its width by at least eleven times and the charge body having a specific density of at least 1.1 metric tons/m.sup.3. Each of the rams has a ram body and a ram rod extending upwardly from the ram body, the ram rod being engaged and clamped for joint lifting by one or a pair of lifting members. Each lifting member is pivotally mounted on a shaft and has an eccentric engaging surface which comes into engagement with the respective ram rod. When two lifting members are associated with each ram rod, both of them are pivoted in synchronism. In the upper position of the ram, each lifting member releases the respective ram rod to permit the respective ram to descend onto the particulate bed in a free gravitational fall. The individual rams are mounted on one or more carriages which are reciprocatable longitudinally of a mold in which the particulate bed is confined by such a distance that the entire exposed surface of the particulate bed is acted upon by the rams. The movement of the carriages and that of the rams are independent of one another.
