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.

A pulverizer for reducing a size of input material particles having a housing, a rotatable shaft with rotor arms and at least one airflow deflector cooperating with the rotor arms to deflect airflow within the pulverizer so as to form at least two overlapping vortices within the interior chamber such that input material particles in suspension in both overlapping vortices collide with each other to be thereby pulverized. The pulverizer also having a housing liner including a plurality of housing liner portions attached to and extending along a outer structural wall of the housing. The pulverizer also having a housing sidewall having an outer structural wall with a plurality of wall sections. The pulverizer also having canted rotor arms and rotor arms with removable wear pads. An anti-caking device for a vessel such as a pulverizer is also provided.

A pulverizer may have such features as an ability to detect wrapping as well as possibly deter wrapping. A processor may also adjust the speed of rotation of the arms within the pulverizer and/or the speed of feed of input for various considerations. In fact the rotation direction may be reversed for at least brief periods of time in an effort to remove wrapped material. Vibration may also be sensed and efforts to prevent damage may be instigated by a processor.

Apparatus (1) for homogenization and separation of substance mixtures composed of particles, having two or more material discharges, wherein a rotating drum (5) is provided, which comminutes and homogenizes the substance mixture, on the one hand, and accelerates the particles in a predetermined direction.

A method and related apparatus for liberating particles with specific dimensions from a moist Municipal Solid Waste Incinerator ash (MSWI ash) material comprising particles with differing dimensions. In an aspect, the method comprises feeding an amount of the material in a particle stream, striking the particle stream with a striking body to impart a sudden change in direction of the particle stream, receiving at least a part of the stricken particle stream on a moving surface, and transporting the received particle stream to an outlet beyond the receiving area where the particle stream is divided in a first fraction rich of particles of a first group of particle dimensions, and at least a second fraction rich of particles of a second group of particle dimensions, which second fraction is substantially depleted of particles of the first group of particle dimensions.

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 portable system and method for processing waste to be solidified and placed in an active cell of a landfill. A portable pugmill is moveable adjacent an active cell of a landfill; and portable devices, which may be mounted on sleds or trailers, may be used for feeding the pugmill with waste to be solidified into a landfill-ready state. The waste may be fed to the pugmill without the need for long-term waste storage devices, and avoiding substantial delays between discharge of the waste from trucks to the pugmill-feeding steps.
