Briquetting press

Piston or ram type briquetting presses are operated as follows. The material to be briquetted is placed into a forming die which is closed on all but one side face. A close fitting ram or piston then enters into the die s open side and exerts the force required to produce the briquet. The briquet is then ejected or stripped out of the die. The ram or piston (which is also sometimes referred to as the stamp or punch) which enters into the die can be actuated either mechanically or hydraulically. A typical installation has the following characteristics ...

The difference in behavior between single- and multirow briquetting presses Above, the different behavior of wide roll compactors as compared to narrow rollers has been discussed. Roll-type briquetting presses feature even more pronounced differences if single-row designs are compared with multirow applications (i.e. two or more pockets across the face of rollers).
