A piston assembly for a gyratory crusher that contains designed wear parts comprising an upper piston bushing, a lower piston bushing, a piston wear ring and a hydraulic seal. All the wear parts can be replaced without access to the underside of the crusher
摘要:
A gyratory crusher, which includes a bowl, a head assembly and a cylindrical eccentric assembly. The bowl is shaped as a cone and has a wider opening approaching a top portion of the crusher, and an inner shell, which is backed by a concrete outer shell. The head assembly is shaped as a cone, and is centrally located within the bowl. The head assembly also includes a central mainshaft which is located on an inclined axis within the bowl. The cylindrical eccentric assembly includes an eccentric central volume in which the main shaft is held so that, as the eccentric assembly rotates, the mainshaft gyrates, with the eccentric assembly rotating about a center hole within a central hub of the crusher. A method of making or retrofitting a crushing device such as, for example, a cone crusher or other gyratory crusher, is also provided.
摘要:
The apparatus is a gyratory crusher in which all the wear parts can be removed and replaced from the top of the crusher, thus eliminating the need to remove large, heavy parts from below the crusher. This is accomplished by constructing the crusher so that the eccentric and the piston assembly can be lifted up and out sequentially. The piston assembly then includes all the wear parts within the lowest assembly, the hydraulic support, so that those parts can be replaced without access to the underside of the crusher. If necessary, the hydraulic support within which the piston assembly is held can also be removed from above the crusher.

A system for billing hotel guests for playing visual content in a hotel room may be utilized by a hotel. The system may include a display system located in the hotel room. A computing system may be in communication with the display system and include a processor and memory. Software may be executed by the processor for displaying a menu on the display system to enable a hotel guest to select visual content to play on the display system. The software may further enable the hotel guest to select a payment option to apply charges for playing the visual content on a separate bill from a regular bill, where the regular bill includes hotel room rental charges.
摘要:
A method, or corresponding apparatus, for controlling deformation of a structure, in part, includes applying a command signal at a first signal level to at least one actuator mechanically coupled to a structure, the first signal level known to produce an energy level in the actuator(s) substantially the same as an energy level currently stored by the actuator(s). The method enables the actuator(s) to respond to the command signal by applying an electrical reference to the actuator(s). The method drives the command signal from the first signal level to a second signal level, changing the actuator(s) in at least one dimension as a function of the command signal, which results in a corresponding deformation of the structure. The method electrically disables the actuator(s) by removing the electrical reference, which results in maintaining deformation of the structure defined by energy stored by the actuator(s).

An electronic device comprises a face with a multi-level surface characteristic that reduces the surface area in contact with a user of the device, thereby attenuating the heat transfer between the device and the user, and therefore also attenuating the touch temperature of the device surface.
摘要:
A method of measuring one or more motion parameters of a main shaft in a gyratory or cone crusher is disclosed. Signals are directed from a stationary sensor means located apart from the main shaft to one or more signal reflective surfaces situated on a target located on or adjacent to an upper portion of the main shaft. The target rotates and otherwise moves in unison with the movement of the main shaft. From the elapsed time the distances from the sensor the reflective surfaces on the target are determined. Analyzing the distances over time will yield information on the movement of the main shaft.
