Provided is a solid fuel pulverizing device (100) provided with: a ventilation unit (30) configured to ventilate an interior of a housing (11) with primary air for supplying a solid fuel pulverized by a roller (13) to a classifier (16); a pressure detector (50) configured to detect an internal pressure of the housing (11) relative to a reference pressure; a flow rate detector (60) configured to detect a flow rate of the primary air blown into the interior of the housing (11) by the ventilation unit (30); and a controller (40) configured to perform control and transition the solid fuel pulverizing device (100) to a stopped state upon the internal pressure detected by the pressure detector (50) being a predetermined pressure or higher and the flow rate of the primary air detected by the flow rate detector (60) being a predetermined flow rate or less.

An equipment for shredding various meats, cooked and/or pre-cooked, deboned, whether of ox, chicken or other animals, equipped with a meat striping system to shred it without crushing it, with simple and resistant structure, motorized and coupled directly to the motor shaft for productivity gain, and also, with components of modern and functional design, which provide efficiency and safety for the operator during handling. The present meat defroster is constituted by a rectangular-shaped bench (1), provided with four legs, with motor and shaft mounted horizontally.

Disclosed is a data logging apparatus comprising a mixer grinder which includes a tub configured to hold a product, a rotatable shaft, at least one mixing blade connected to the rotatable shaft, a grinding chamber, and a feed screw leading to a grinding head. The data logging apparatus includes a first temperature sensor attached to the tub, a second temperature sensor attached to the grinding chamber at an outlet downstream from the grinding head, a memory storing a predetermined temperature threshold, and a processor. The processor is configured to receive temperature data transmitted from the first temperature sensor and the second temperature sensor, determine whether an abnormality has occurred based on received temperature data and the predetermined temperature threshold, and issue an alert indicative of machine malfunction or maintenance issues.

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.

A jaw crusher assembly comprises a jaw crusher a jaw liner clamping tool for clamping a jaw liner to a jaw of the jaw crusher. The clamping tool comprises a clamping head pivotably coupled to a shaft, and a releasable fastening mechanism. The shaft passes through the jaw and its free end is fastened to the jaw by the fastening mechanism, which is tightened to cause the clamping head to exert a clamping force to hold the jaw liner in place. The clamping tool facilitates safe installation of the jaw liners.

A grinding mill for pulverizing material includes a platform having an upper surface and defining a recess having a floor, the recess configured to seat a dish in which the material is disposed, and a movable securing frame that is movably connected with the platform, the frame including a lift support having an upper surface that is movable along a path from a first location that is beneath the floor of the recess, through the recess, to a second location that is coplanar with the upper surface of the platform. A motor configured to cause oscillation of the platform and the movable securing frame can be used. A method of using the grinding mill can include placing a dish above a recess defined by an upper surface of a platform, and lowering the frame with respect to the platform, thereby seating the dish within the recess.
