A method for disposing of propellant containers containing a propellant, comprising submerging the propellant containers in a detonation suppressant liquid, shredding the propellant containers while submerged in the detonation suppressant liquid into shredded propellant container material reduced in size to provide release of the propellant from the propellant containers, and removing the shredded propellant container material from the detonation suppressant liquid. A system for disposing of propellant containers is also disclosed.

A shredding arrangement for shredding material to be shredded, such as household waste, industrial waste, plastics, wood, paper and/or biomass, comprising a shredding device, which is arranged on a machine frame, and a supply device having at least one infeed roller drivable to rotate using an associated drive device for supplying the material to be shredded to the shredding device. The shredding arrangement is distinguished in that the infeed roller is configured to accommodate the associated drive device, and the drive device has an electric motor, gearing, and a flexible coupling.

A material reducing machine includes a rotary reducing drum that is rotatable about an axis of rotation and defines a reducing boundary that extends at least partially around the axis of rotation. The material reducing machine includes an infeed conveyor for transporting material to a front portion of the rotary reducing drum and defines a conveyor plane. The material reducing machine includes a mill box at least partially surrounding the rotary reducing drum and including a mill box lid mounted generally above the rotary reducing drum. The mill box lid has an inlet edge positioned above a rear portion of the rotary reducing drum and an outlet edge positioned above the front portion of the rotary reducing drum. The mill box includes an infeed opening that is configured to receive material from a feed table and has an upper opening defined by the outlet edge of the mill box lid.

A hopper and a mineral material processing plant. The hopper includes hinged side walls configured to be pivoted into a first position and a second position and a connection wall attached between the hinged side walls. The connection wall includes a flexible member and is configured to fold together in response to the hinged side walls being pivoted from the first position to the second position.

A conveyor assembly for raising and feeding debris such as fallen branches from an orchard floor to a processor such as a wood-chipper is provided. The conveyor assembly comprises a body including a floor having a leading end for location adjacent ground level and a trailing end for location above the leading end in use. A ground contact arrangement is located toward the leading end extends beneath the leading end to thereby raise the leading end above ground level. A powered leading feed roller is disposed adjacent the leading end of the floor to direct members from ground on to the floor. A powered, primary infeed roller is located rearward the leading infeed roller and is arranged to move toward and away from the floor to accommodate members between said roller and the floor and urge the members, such as fallen branches rearward for entry into an inlet of the wood-chipper.

An infeed system is provided for a chipper or grinder having a processing portion wherein an item is processed into smaller pieces. The infeed system is upstream of the processing portion and includes a feed roller, a first hydraulic motor in communication with the feed roller for selectively actuating the feed roller, a second hydraulic motor in communication with the feed roller for selectively actuating the feed roller, and a hydraulic pump for providing hydraulic fluid to the first and second motors. A directional control valve and a relational control valve are between the pump and the motors. The directional control valve allows the hydraulic fluid to operate the first and second motors in a forward direction and in a reverse direction, and the relational control valve allows the hydraulic fluid to operate the first and second motors in series and in parallel.

A portable grinding/shredding/chipping system with a drive track assembly which is manipulatable to facilitate altering the orientation of the portable grinding/shredding/chipping system. This arrangement results in improved loading and processing, of both long and short materials, as well as facilitates connection of a transport dolly and a transport truck/tractor without requiring any additional lifting mechanism. A pivotable housing provides greater access to the rotor and has an over-center arrangement which prevents the pivotable housing from inadvertently moving or pivoting back into engagement with the rotor. The portable grinding/shredding/chipping system is provided with a belt drive assembly which facilitates modification of the rotational speed of the rotor by merely replacing a sheave of the belt drive assembly. Lastly, both head and tail pulleys are driven by a respective motor so that a catinary of the discharge conveyor is radiussed which shortens an axial length of the system.

A method for disposing of propellant containers containing a propellant, comprising submerging the propellant containers in a detonation suppressant liquid, shredding the propellant containers while submerged in the detonation suppressant liquid into shredded propellant container material reduced in size to provide release of the propellant from the propellant containers, and removing the shredded propellant container material from the detonation suppressant liquid. A system for disposing of propellant containers is also disclosed.

A material processing machine for material reducing operations. The material processing machine comprises an infeed system, a reducing system, and a discharge system. The reducing system comprises a rotor having processing tools to reduce the material within a reducing chamber. A colorizer system directs colorant from a colorant source towards the material reducing system within an outlet zone. The colorant colorizes the material being reduced within an inlet zone. The reduced material may be discharged through one or more screens within the outlet zone such that negligible colorant is applied directly to the reduced material. The material reducing operations may comprise a two-stage reducing operation in which the colorizer system is inoperable for the first stage and operable for the second stage. The screens may be selectively interchangeable between stages to incrementally reduce the material to provide substantially uniform colorizing and material size.

A mobile shredder for metal materials comprising a feeding device, a shredding mill with a plurality of hammers associated with a rotor, and a removal device and an actuating device are provided, wherein: the feeding device comprises a hopper and a shredder with a first toothed roller and a second toothed roller that rotates in the opposite direction to that of the first roller and at a greater speed. The actuating device comprises a single motor. A control system is also provided with a plurality of hydraulic pumps for moving the rollers and a hydraulic clutch with a variable flow for moving the rotor, the plurality of hydraulic pumps and the hydraulic clutch being joined to the motor. The control system is configured to modify the rotational speed of the toothed rollers based on the motor load associated with the shredding mill; and the devices are mounted on a frame.
