In a discharge portion liner attachment structure for a vertical shredder including a sweeper supported below a rotor in such a manner as to be coaxial with a rotation shaft, a discharge ring disposed on a circumference portion of the sweeper, and a discharge portion through which a shredding target object that has been swept out through an opening formed on a circumference wall of the discharge ring by a sweeping operation performed by the sweeper is discharged to outside, discharge portion liners are attached in such a manner as to protrude from a side of the discharge portion to a side of the discharge ring in such a manner as to cover edge portions of ones of the discharge ring liners on a side of the opening.

Disclosed is an underwater crushing mechanism for an aluminum housing battery, including a crusher, where the top end of the crusher is provided with a feed port, and a crushing mechanism is arranged inside the crusher below the feed port; a water body is stored in an inner cavity of the crusher, and the crushing mechanism is immersed in the water body; the crusher is provided with a spray mechanism; the crusher at the side of the spray mechanism away from the feed port is provided with a channel communicated with the inner cavity of the crusher, an opening is provided at the side of the channel away from the spray mechanism, and at least two crushed material collection chambers are arranged in the crusher at the side of the opening; and a collection frame is movably arranged in the channel.

Reflective luminescent markings on a road or sign surface are formed by applying onto the surface a base material which is liquid in an initial state for application and sets or cures to form a solid layer after application where the base material contains a fine/medium filler material of glass ground from recycled materials in a rotary mill. Coarse material from the grinder is separated out and supplied as a separate material to be applied onto the surface of the layer of base material and fine ground glass. The base material is connected or impregnated with a luminescent material such as photo luminescent 2 4 6 trichlorophenyl in a binder such as polyurea.

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.

A system and mechanism for bottom ash flow turndown from a hopper, through a crusher, and to a conveyor, the system including a fixed flow restrictor and a variable speed side discharge crusher to modulate bottom ash flow in the absence of gate or valve flow from a hopper, the conveyor providing a signal corresponding to an overfeed condition to enable a controller to operate the crusher and/or the conveyor to eliminate overfeed conditions.

Provided is a non-belt automatic mechanized sampling system for a train, including: a working platform provided with a slide rail; a sampling mechanism slidably arranged on the slide rail and configured to collect materials from the carriage of the train; an integrated sample preparation component including a discharging mechanism and a feeder, a crusher, a constant mass dividing machine and a sample retention barrel arranged from top to bottom. The feeder transports the material to the crusher. The crusher crushes the material and transports the crushed material to the constant mass dividing machine. The constant mass dividing machine divides the crushed material into samples to the sample retention barrel, and the discarded material to the discharging mechanism. The discharging mechanism transports the discarded materials to the carriage.

A system and mechanism for bottom ash flow turndown from a hopper, through a crusher, and to a conveyor, the system including a fixed flow restrictor and a variable speed side discharge crusher to modulate bottom ash flow in the absence of gate or valve flow from a hopper, the conveyor providing a signal corresponding to an overfeed condition to enable a controller to operate the crusher and/or the conveyor to eliminate overfeed conditions.

A rock processing apparatus is provided for crushing and/or sorting granular mineral material according to size. The rock processing apparatus comprises a material feeding apparatus including a material buffer, at least one working unit of at least one crushing apparatus and at least one screening apparatus, at least one conveyor apparatus for conveying material between two apparatus components, a control unit for controlling apparatus components, at least one sensor for detecting at least one operating parameter, the sensor being connected to the control unit for transmitting a detection signal, at least one output device for outputting information and connected to the control unit. The control unit is designed to ascertain, in an operation with discontinuous material feed, and based on the at least one detection signal, time information about a future material feed, wherein the output device is designed to output the ascertained time information.

A rotary impact separator is provided for separating a material. The rotary impact separator includes a body portion comprising one or more walls. The one or more walls define a substantially hollow chamber, an inlet opening, a first outlet opening, and a second outlet opening. The rotary impact separator includes an impact device extending at least partially into the hollow chamber. The impact device includes a shaft that extends within the hollow chamber. The shaft rotates within the hollow chamber. One or more blades are attached to the shaft and contact the material. A diverter is attached to an interior surface of one of the one or more walls. The diverter extends along the shaft and projects from the interior surface toward the shaft. Methods for recovering two or more co-products from a material are provided.
