A gyratory roller crusher in which the rollers have a corrugated profile and at least one of the rollers is eccentrically mounted to give a relative gyratory motion to the rollers. The arrangement in the gyratory roller crusher results in additional breakage mechanisms for the comminution of a very wide range of feed material, vastly improved crushing ratios and increased throughput.

The invention relates to a chain link for a support chain for supporting a compression belt in a separating device for separating materials of different flowability, the chain link having a support surface and an inner surface opposite said support surface and is characterized in that a protruding support element is arranged on at least one end face of the chain link so as to form an undercut. The invention further relates to a support chain for a support apparatus for supporting a compression belt in a separating device for separating materials of different flowability, the support chain being an articulated chain which has individual chain links connected to each other in an articulated manner, the chain links being threaded onto chain pins extending transverse to the conveying direction F with the chain links according to the invention. The invention also relates to a support apparatus having the support chain according to the invention.

A device for supporting a roller bearing housing of a double-roll crusher is provided, wherein each roller has a fixed bearing with a non-self-aligning design and a floating bearing with a non-self-aligning design, and wherein at least one load distribution element is arranged between the machine frame of the double-roll crusher and the housing of each roller bearing. The at least one load distribution element has at least two elastic, spatially separated individual elements, with at least one recess between the individual elements providing a spatial separation in the vertical direction.

A roller mill module with a fixed grinding roller with a first grind surface rotatably supported within a grind area between a first drive end and a second drive end of a support structure; an adjustable grinding roller with a second grind surface rotatably supported within the grind area; the adjustable grinding roller movable with respect to the fixed grinding roller to adjust a grind gap between the first grind surface and the second grind surface; a drive shaft of the fixed grinding roller and a drive shaft of the adjustable grinding roller extending from the first and the second drive ends of the support structure; and a sample port provided in a front side of the support structure; a sample passage coupled to the sample port extending to a position below the grind area and opposite a sampler stop surface.

The present invention relates to a machine frame for a roll crusher that has two side walls and two end walls, where the mentioned end walls accommodate the storage of the rolls. The end walls are split horizontally in the area of the mounting of the rollers, and vertically between the mountings of the upper part. One advantage is that to remove a roller, removal of the respective upper end wall is sufficient. In a preferred embodiment of the invention, the adjacent upper parts of the end walls do not touch. An advantage of this is that tilting of the end wall upper parts among each other or in contact with the side walls is prevented during removal. Furthermore, the gap resulting from the distance between the front wall upper parts in the preferred embodiment would be sealed, with the advantage that no material and dust can exit.

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 vehicle and method of use in subsea operations related to crushing concrete mattresses including at least one lift assembly, at least one crushing roller, at least one blow out pipe cable of blowing crushed concrete mattress fragments into a rubble container. In a preferred embodiment, the vehicle has at least one fork lift connected to the lift assembly, a digger chain assembly arrangement, treads, an interface connected to the vehicle and capable of engaging the rubble container, and each rubble container is detachable from the interface.

A 3D-slanted roll crusher includes a housing, a number of driving devices mounted to the housing, a base mounted to an end of the housing away from the driving devices, a number of groups of grinders, a number of grinding teeth mounted on each of the grinders, and a number of material obstructing bodies mounted on an inner wall of the housing. The grinders correspond to the driving members one-to-one. Each grinder is connected to the base and the corresponding driving device. The grinders are spaced equally apart within the housing around a central axis of the housing and slantedly mounted on the base facing the driving devices.

A carrying device (1) for the frontal removal of a roll body from a roll frame, comprising a main frame (2) and a receiving section (3) for the roll body. The receiving section (3) can be transferred from an introduction position (E) into a supporting position (S). The receiving section (3) has a profile which at least partially encloses the roll body in the supporting position (S), and the carrying device (1) can be pushed in below the roll body with the receiving section (3) in the introduction position (E), and the roll body is carried with the receiving section (3) in the supporting position (S).
