摘要

The press rolls for treatment by pressure or compaction of granular material and method for centralizing the gap of roll of a press roller.The invention relates to a press roller (100) for treatment by pressure or compaction of granular material, comprising at least two rolls (110120) configured as movable rollers, which are mancalizados, in each case, alternately in a machine structure (171) through D And an axis (11111 2121122)Are driven in counter rotation and are separated from each other by means of a gap roller (115), in which the axes (11111 2121122) of the rollers (110120) are accommodated in the accommodation of the bearing (130140150160) mancalizados as mobile in the machine structure (171) and in which in each case. S bearing housing (130140150160) arranged on one side of the rollers (110)120) and belonging to different rolls (110120) are connected to each other by means of at least one cylinder pressure (210210 39, 220, 220, 230, 230 39 , 39 240240 , 39 ). According to the invention, the connection between the housings of the bearing (130140150160) in each case has at least a balance of torque (250250 39 260260 , 39 ).In this way, the structure of a press roller comprising a centering roller is simplified when compared with the state of the art and can be produced in a more economical.
