<p>The rear end of a rotary drying drum (1) is provided with a peripheral channel (10) in which dried material to be briquetted, such as green crops, wood flakes or peat, is accumulated and carried along. The bottom of the channel (10) is formed by the inner periphery of a ring of dies (18), in which the formation of briquettes takes place by means of a pressure roller (17) operating in the channel (10) and compressing the material against the frictional resistance in the dies. The material has previously been precompressed by an endless band (19) likewise operating in the channel (10), which band preferably runs at the same peripheral speed as the pressure roller (17) and the inner side of the die ring (18). </p> |
