摘要： A roller mill for comminuting bulk material may include a first grinding roller and a second grinding roller that are arranged opposite one another and can be driven in opposite directions. A grinding gap exists between the grinding rollers. A floating bearing unit may be configured to receive the first grinding roller, and a fixed bearing unit may be configured to receive the second grinding roller. The floating bearing unit includes two bearings, each of which receives one end of the first grinding roller. Hydraulic actuators are mounted on the floating bearing unit for applying a force to the floating bearing unit. The bearings of the floating bearing unit are connected to one another via a synchronization device that includes a coupling element, which in a coupling position prevents a relative movement of the bearings and in a free position permits a relative movement of the bearings.

摘要： A supporting device includes first and second supporting flanges coupled with first and second transmissions, respectively, and a support via which a supporting force is transmittable from the first supporting flange to the second supporting flange. The support includes a lever element which is coupled in an articulated manner with an attachment element on the first supporting flange and thus articulated with the first supporting flange, and a supporting element which is coupled in an articulated manner with the lever element and connected to the second supporting flange and which includes two spaced-apart supporting parts. The lever element is arranged partly between two spaced-apart attachment parts of the attachment element and partly between the supporting parts of the supporting element and is coupled in an articulated manner with the attachment element via the attachment parts and in an articulated manner with the supporting element via the supporting parts.

摘要： A grinding roll including a roll body having a cylindrical outer surface extending axially between a pair of opposite ends and a side groove formed at each end of the roll body. The side groove includes a support shoulder recessed from the cylindrical outer surface and/or from surfaces of the opposite ends of the roll body. The grinding roll includes an edge ring including a plurality of spaced receiving cavities and a plurality of wear members. Each wear member is received and retained in at least one of the receiving cavities of the edge ring. The wear members are positioned along the edge ring to define an edge of the grinding roll, and the edge ring is received within each side groove. The wear members are arranged to provide a wear protecting surface which is angled in relation to the cylindrical outer surface of the roll body. The angled wear protecting surface prevents excessive build-up of material on the grinding roll and reduces the need for maintenance.

摘要： The invention relates to a method for monitoring a high-pressure roller press in the course of comminuting, compacting, or briquetting material. The roller press has two rotationally driven press rollers, between which a rolling gap is formed with a gap width that can be modified during operation. During operation, operational data of the roller press is ascertained by one or more measurement value sensors and is stored on a computer. The method is characterized in that the operational data is stored as raw data on an edge computer, as an analysis computer, which is stationed locally in the region of the roller press and is connected to the measurement value sensors, and the raw data is evaluated on the analysis computer using an analysis algorithm so that characteristic data of the roller press is generated and stored on the analysis computer, wherein the characteristic data is transmitted from the analysis computer to at least one terminal via a wireless network and is displayed on the terminal.

摘要： The invention relates to a high-pressure roller press (1), in particular a material bed roller mill or a compacting machine, comprising two press rollers (3, 4) which are rotatably mounted in a press frame (2) and are driven in opposite directions and between which a pressure zone (5) is formed with a rolling gap (S) arranged at the height of the roller axis (X, X′), the gap width (W) of said rolling gap being variable during the operation of the roller press (1), wherein the pressure zone (5) between the press rollers (3, 4) is delimited at the roller end faces by delimiting plates (8) arranged laterally next to the press rollers (3, 4), and the delimiting plates (8) are secured to the press frame (2) in a movable manner and under the application of a force such that the delimiting plates (8) can be pushed back against the applied force during the operation of the roller press (1). The invention is characterized in that an individual roller (10) is secured to each delimiting plate (8) at the height of the rolling gap (S), said roller being rotatably mounted about the roller axis (Y) of the roller and laterally delimiting the rolling gap (S).

摘要： An actuator is configured to couple with a controlled member and includes first and second pistons disposed in respective internal chambers. The first piston may be moveable between first and second positions. The second piston may be moveable between third and fourth positions. The second piston may be configured not to engage the first piston when the second piston is disposed at the third position. The second piston may be configured to move the first piston to the second position as the second piston moves from the third position to the fourth position. A resilient member may be disposed to resiliently urge the second piston toward the fourth position.

摘要： A roller press device for milling input material may include a fixedly mounted fixed roller having a roller shaft mounted at least approximately in a fixed position, a loosely mounted loose roller having a roller shaft that can be arranged in a variable position, a frame supporting at least the fixed roller and optionally also the loose roller, and a force application unit acting on the loose roller at a force application point. The fixed and loose rollers can be mounted and positioned relative to one another for applying a milling force. The loose roller may be mounted so as to pivot about a pivot axis in a manner of a one-sided lever such that the relative position of the loose roller relative to the fixed roller can be defined by said pivot movement. The one-sided lever may be formed between the pivot axis and the force application point.
