Disclosed is a deflection distributor refitting kit for a roller crusher. According to the disclosure the deflection distributor refitting kit comprises a deflection distributing shaft, thrust rods each having first and second ends and mounts for attachment of the deflection distributing shaft at a frame of the roller crusher, wherein a first end of each of said thrust rods is attached to the deflection distributing shaft via a lever, wherein a second end of each of the thrust rods is arranged to be attached to a movable bearing housing of the roller crusher, and wherein the deflection distributor refitting kit further comprises a preload arrangement which induces a bias to parts of the deflection distributor refitting kit. Also disclosed is a method for mounting the deflection distributor refitting kit, as well as a roller crusher comprising a deflection distributor.

A shredding device is provided comprising two shredding shafts arranged parallel to each other with shredding elements arranged thereon, wherein the shredding shafts are preferably rotatable mechanically synchronized to each other. A shaft-side coupling element is connected to a respective first end of the shredding shafts. The shredding device includes a housing with a housing-side coupling element is provided that can be coupled to the shaft-side coupling element. The shredding device includes a displacement device enabling displacement of the shredding shafts for decoupling and coupling the shaft-side coupling element from or to the housing-side coupling element.

Roller packages (IO) for grinding devices (70), comprising a first roll (11), which is maintained by at least one first bearing body (13), and a second roll (12), which is maintained by at least one second bearing body (14). The first bearing body (13) and the second bearing body (14) are prestressed against each other and comprise stop elements (17,19) with stop surfaces (18, 20), the contact of which counteracts a contact of the rolls (11, 12). The rotational position of the first stop element (17) determines the minimum width of the grinding gap. Also disclosed are grinding devices (70), methods for operating a roll assembly (10) and methods for determining the radial force acting between the rolls (11, 12) of a roll assembly (10).

A roller press machine capable of applying an electric field includes a base, a frame, press rollers, a distance adjusting device, a speed adjusting device, a voltage applying device, a feeding baffle, and a discharging device. The press roller has a roller surface made of conductive material, and an electric field is created when a charge is applied to the press roller. In the roller press, an alternating or direct current electric field is applied between the press rollers to create an electrochemical action, such that particles or a solution in a system is induced to undergo a physical or chemical change, thereby enhancing interaction therebetween, and accordingly increasing grinding and dispersion efficiency of a solid-liquid dispersion system.

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.
