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.

A pulverizer apparatus includes a first rail assembly and a second rail assembly. The first rail assembly includes a first plurality of rails. Each of the first plurality of rails are separated from each other by first gaps. The second rail assembly includes a second plurality of rails separated from each other by second gaps. A first linear actuator is secured to the first rail assembly. The first rail assembly is movable along a first linear path via actuation of the first linear actuator. The first plurality of rails is receivable in the second gaps of the second rail assembly.

A crusher includes a housing having an inlet and an outlet at opposite axial sides, an impeller positioned proximate the inlet of the housing, and a shaft connected to the impeller and extending axially through the housing between the inlet and the outlet. At least two spaced apart support structures hold the shaft in the housing, where a plurality of dynamic blades extending outwardly from the shaft are alternatingly positioned between a plurality of fixed blades extending radially inward from an inner wall of the housing.

A hydraulic breaker without a back head, includes a main control valve, to which fluid is supplied from the outside of the polyhedron, and accommodating a pilot valve for controlling the main control valve, in the interior space of the polyhedron, and in which impact force is obtained by double-acting cylinders, operated by the main control valve, moving modules that are connected to piston rods backwards and forwards, thus moving an integrated impact ram and ram block module forward, and filled compressed gas rapidly pulling back the integrated impact ram and ram block module.

In one aspect there is provided a jaw crusher including a motor providing a primary power source to a primary hydraulic pump of the jaw crusher, a crusher frame supporting a fixed jaw and a movable jaw defining a crushing chamber therebetween, a cross beam transversely mounted in the crusher frame, a toggle plate extending between the cross beam and the movable jaw, and a hydraulic system having a primary pump line powered by the primary hydraulic pump for moving the movable jaw and clamping the toggle plate. The hydraulic system includes an auxiliary pump powered independently of the primary pump for effecting movement of the movable jaw.

A crusher apparatus includes a material crushing portion with a first crushing portion adapted for movement toward a second crushing portion. A linkage subassembly is connected to the first crushing portion and includes a first and second member operable about a pivot. A force inducing subsystem exerts a counterforce of a predetermined threshold amount to the first and second members sufficient to maintain the linkage subassembly in an unrelieved position until a crushing force exerted on the first crushing portion is sufficient to cause the linkage subassembly to move into a relieved position.

A medical waste treatment system, comprising: (1) A main treatment unit comprising: a waste receiver cover comprising a UV lamp; a waste shredding unit comprising a shredding bin and at least two rotating shredding blades; a compression unit to push the medical waste towards the shredding blades; a separator to allow the passage of shredded medical waste of a predefined shape and diameter; and a disinfectant delivery unit comprising a plurality of nozzles. (2) A disinfection unit which comprises a disinfectant mixing bin and a mixing unit. (3) A main liquid management unit comprising a disinfectant delivery unit that comprises a plurality of nozzles interconnected to the main treatment unit. (4) A separator unit to separate the liquid from shredded waste; and a centrifuge to further remove liquid from the shredded waste.
