Systems and methods for downsizing tires, and an automated downsizing apparatus utilize a cradle, mandrel table, cutting apparatus, and a control unit. In various embodiments, a tire mounted on the cradle may be received by the movable and rotatable mandrel table, and positioned for engagement with the cutting apparatus. Users may customize one or more cutting configurations 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 configurations. During tire downsizing operations, one or more system parameters may be monitored to determine compliance with the selected configuration, and the automated execution may be manually overridden.

A resettable relief system for a crusher is provided. A first linkage member is connected to a material crushing portion of the crusher is connected to a second linkage member in a hinged manner. A hydraulic device exerts forces to the linkage members sufficient to maintain them in an unrelieved position, until forces exerted on the linkage members from the material crushing portion exceed a predetermined threshold, and then permit said first and second linkage members to move into a relieved position.

A mechanochemical reactor includes an outer shell. A first plate is slidably disposed within the tubular outer shell at a first end of the tubular outer shell and a second plate is slidably disposed within the tubular outer shell at a second end of the tubular outer shell, the second end being opposite the first end. A linearly-reciprocating mill is disposed within the tubular outer shell between the first plate and the second plate. A first electromagnet is operatively coupled to the first plate so as to establish a position and a holding force of the first plate within the tubular outer shell, and a second electromagnet is operatively coupled to the second plate so as to establish a position and a holding force of the second plate within the tubular outer shell.
