A method for measuring the displacement of a surface relative to a base reference. The method includes generating point cloud data between a reference point and a surface disposed distally from the reference point to define a three dimensional image of the surface. The method also includes determining the location and direction of key reference parameters of the object defined by the three dimensional image from the point cloud data. The method also includes obtaining base reference data in a prescribed co-ordinate system in respect of a base reference relative to the surface. Further, the method provides for processing the point cloud data and the base reference data, orientating the point cloud data relative to the key reference parameters defined by the base reference data and transforming the point cloud data into a co-ordinate system coinciding with the base reference data.

A drive arrangement for a roll crusher includes two rollers arranged in parallel, two trains, each for driving a roller. The two drive trains each has a gear transmission including a drive shaft which can connect to a motor and an output shaft which can connect with a roller. Each gear transmission includes an intermediate shaft arranged between the drive shaft and the output shaft. The intermediate shafts are connected to each other via a slip-free torque transmission device which allows an offset of the gear transmissions in relation to each other in combination with a torque limiting clutch which terminates the connection for a conjoint rotation of the intermediate shafts when an adjustable torque is exceeded.

A roller press arrangement, a connection device for movably attaching certain parts to the roller press and a method for more easily performing maintenance on such parts is disclosed. The roller press comprises a frame assembly and a force generation device. The force generation device configured to move so that it is removable when top members of the frame assembly are connected to the side members of the frame assembly and fixed in a closed horizontal position. The connection device for attaching a force generation device to the frame assembly comprises a mounting plate and a hinge. The hinge is rotatable so that the force generation device is removable when top members of the frame assembly are connected to side members of the frame assembly and the top members of the frame assembly are fixed in a closed horizontal position.
