<p>A pelletizer comprising an annular drivable press mold (5) mounted in the frame (3) and press rollers (6) mounted in bearing journals (16,22) and drivable by said press mold (5) the shafts (13) of said press rollers (6) being eccentric relatively to said bearing journals (16,22). The pelletizer further includes an adjustment device for varying the position of said press roller shaft (13) consisting of at least one hydraulic adjustment cylinder (8) whose ends engage with adjustment cranks (39) connected to the bearing journals (22) of the press roller shafts (13). The oil supply and discharge pipes (9) of each hydraulic adjustment cylinder (8) extend through the main shaft (2) of the pelletizer. Adjustment of press roller (6) can take place in a controlled manner when the pelletizer is in operation, i.e. when the press mold is rotating.</p> |
