A high-pressure pump for the overload protection of a jaw crusher, with an actuator unit which adjustably receives an actuation element in a housing, wherein the actuation element has at least one piston, wherein at least one actuator, tensioning cylinder and a pressure accumulator are provided, wherein the actuator unit is in fluid-conveying connection with the actuator such that in one pump stroke of the actuator unit a transfer fluid is pumped into a second chamber of the actuator and of the tensioning cylinder and the quantity of transfer medium displaced from the actuator, and the tensioning cylinder during the pump stroke is temporarily stored in a pressure accumulator.

A rock crushing device includes a housing with a plurality of walls defining a chamber that has an upper inlet and a lower outlet. At least one of the walls is movable relative to another wall to define a primary compression assembly for crushing rocks within the chamber via mechanical force. There is an auxiliary crushing assembly connected with at least one of the walls to deliver a vibratory force to at least one wall for crushing rocks within the chamber. The auxiliary crushing assembly is operable together with the primary compression assembly or independent of it.

The present disclosure relates to a monitoring system for a hydraulic system in a comminution apparatus including at least one pressurized accumulator. The monitoring system includes at least one pressure sensor and a control unit, wherein the pressure sensor is connected to the control unit. The pressure sensor is arranged to measure a pressure in the at least one accumulator and the control unit is configured to determine that a pressure in the accumulator is outside of a predefined range. The control unit is further configured to control a pressure regulating system that is arranged to restore the pressure in the pressurized accumulator.

Disclosed is a fragmentation unit including: —a frame in which there extends a region for receiving a bag, the contents of which is to be fragmented, the region being delimited by the ground and by four virtual planar vertical faces, and divided into a front area and a rear area of equal dimensions by a vertical plane, —at least two pressure plates that are able to move towards each other and vertically, each having a front edge and a vertical planar pressing face, having a rear edge, the rear edge being situated behind a plane containing the virtual planar rear face, and the front edge being tangential to a vertical plane parallel to the plane and dividing the front area of the region into two sub-areas. Also disclosed is a fragmentation method.

Systems and methods for downsizing tires are disclosed. An automated downsizing apparatus comprises a cradle, mandrel table, cutting apparatus, and a control unit. A tire mounted on the cradle may be received by the movable and rotatable mandrel table, and positioned for engagement with the cutting apparatus. A user may customize a cutting configuration to be executed by the control unit. The control unit positions the mandrel table and cutting apparatus to remove portions from the tire, according to the cutting configuration. During operation, one or more system parameters may be monitored to determine compliance with the selected configuration, and the automated execution may be manually overridden.
