An adapter method and system includes a first side deflector, a second side deflector, and a top deflector coupled to the first side deflector and the second side deflector. The system may further include an internal deflector coupled to the first, second, and top deflectors. A first leg is coupled to the first side deflector and a second leg is coupled to the second side deflector. The legs are adjustable between a first position and a second position. The first, second, and top deflector define an entrance region for channeling wood-based debris into the chute of a woodchipper. Each side deflector may include a coupling mechanism for attaching to a woodchipper. Each coupling mechanism has an aperture. Each leg may telescope within a respective side deflector.

The present invention discloses a device for pulverization and explosion suppression of low carbon gas hydrate (LCGH). A feeding chamber connects with a pulverizing chamber, and the chambers communicate through a feed port. A pulverizing air pipe and the feeding chamber communicate through a feeding air pipe; two ends of a venturi connect with an entrainment chamber and a disperser respectively; and a gas-solid separation membrane (GSSM) is disposed on a discharging port and used for preventing LCGH powder from entering the entrainment chamber from the pulverizing chamber. When an explosion is triggered, the GSSM is opened to make the LCGH powder enter the entrainment chamber. The device can store and pulverize the LCGH and spray LCGH powder to achieve combustion and explosion suppression.

A gyratory crusher hydraulic pressure relief valve includes a hydraulic fluid vestibule arranged to be fluidly connected to a hydraulic fluid space. A logic element is arranged to dump hydraulic fluid from the hydraulic fluid space, which includes a plunger having a first plunger surface and a second plunger surface, and a control pipe arranged for fluidly connecting the second plunger surface to the hydraulic fluid vestibule. A supply orifice restricts the flow of hydraulic fluid from the vestibule towards the second plunger surface to make the time TC it takes for the logic element to switch from open position to closed position exceed the time TF it takes for a closed side setting position of the crusher to make one full round.
