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 device for separating material composites to be disposed of, including at least two material fractions with differing material properties, and a method for separating such material composites are provided. The device, in a region of an upper cover plate, has a bowl-shaped dispensing channel having at least one opening facing toward an impact chamber, and a dispenser arranged in the channel and designed to receive material fractions of a second type from the region of the chamber above a first separating screen and/or near the upper cover plate. Individual material fractions of a material composite, such as a material fraction of the second type to be comminuted and having a lower density than a first material fraction, may be separated in larger pieces from remaining material, to facilitate the transport of individual material fractions and further processing as part of raw material recovery.

Discharge grates and grate components of reducing equipment have reduced amounts of material to provide lower costs, lower weight, and less scrap while still providing adequate resistance to bending, deflection, and/or warping and suitable material discharge.

Discretizers that exhibit improved solid additive laden fluid flow emanating from the discretizers and methods of using same, particularly for making fibrous structures are provided.

The present disclosure relates to a rock processing apparatus (12) for crushing and/or sorting granular mineral material (M) according to size, comprising: a material feeding apparatus (22) including a material buffer (24), at least one working unit of: at least one crushing apparatus (14) and at least one screening apparatus (16, 18), at least one conveyor apparatus (26, 32) for conveying material between two apparatus components, at least one discharge conveyor apparatus (29, 42, 46) for conveying processed material onto a stockpile (30, 44, 48), a control unit (60), at least one stockpile sensor (96, 98) for detecting at least one state and/or a change over time of a size of the stockpile (30, 44, 48), the stockpile sensor (96, 98) being connected to the control unit (60), at least one output device (66) for outputting information, the output device (66) being connected to the control unit (60).

The control unit (60) is designed to ascertain, in an operation with a discontinuous reduction of the at least one stockpile (30, 44, 48), on the basis of the at least one detection signal, a piece of reduction time information about an execution time of a future reduction of the stockpile (30, 44, 48), wherein the output device (66) is designed to output the ascertained reduction time information.

The invention relates to a rock processing apparatus (12) for crushing and/or sorting granular mineral material (M) according to size, the rock processing apparatus (12) comprising as apparatus components: a material feeding apparatus (22) including a material buffer (24), at least one working unit of at least one crushing apparatus (14) and at least one screening apparatus (16, 18), at least one conveyor apparatus (26, 32) for conveying material between two apparatus components, a control unit (60) for controlling apparatus components, at least one sensor (72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98) for detecting at least one operating parameter, the sensor (72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98) being connected to the control unit (60) for transmitting a detection signal, at least one output device (66) for outputting information, the output device (66) being connected to the control unit (60) for transmitting information. The control unit (60) is designed to ascertain, in an operation with discontinuous material feed, on the basis of the at least one detection signal, a piece of time information about a future material feed, wherein the output device (66) is designed to output the ascertained time information.

A material processing machine having a reducing system for material reducing operations is disclosed. The reducing system comprises a rotor having processing tools to reduce the material within a reducing chamber. A colorizer system includes a manifold positioned adjacent a screen defining a plurality of apertures for directing colorant from a colorant source through the apertures towards the reducing system. The material reducing operations may comprise a two-stage reducing operation with selectively interchangeable screens that incrementally reduce the material to provide substantially uniform colorizing and material size.

An automatic cleaning device for a ring hammer crusher, and a ring hammer crusher having the automatic cleaning device are provided. The automatic cleaning device includes an automatic cleaning assembly at a back side of a feeding opening of a crushing chamber of the ring hammer crusher; the automatic cleaning assembly includes a material meeting disk and a cleaning blocking rod; the material meeting disk is connected to a drive member and is driven by the drive member to rotate, and the cleaning blocking rod is fixed to the crushing chamber and is cooperated with a material meeting surface of the material meeting disk for cleaning. The ring hammer crusher having the automatic cleaning device has a simple structure and convenient operation, thus improving cleaning effect.

A discretizer having a housing and a rotor movable within the housing, which discretizes a plurality of solid additives from a source of solid additives during operation are provided.

A discharge end wall system including a discharge wall assembly in which a number of pulp chambers are defined, and one or more plug elements at least partially occupying one or more of the pulp chambers.
