A device for sorting particulate material includes a main conveyor belt, a separation screen, a graded material conveyor, and an oversize material conveyor. The separation screen is configured to separate the material into a first portion and a second portion with a larger average particle diameter than the first portion. The graded material conveyor is positioned below the separation screen to receive the first portion of the material, and the oversize material conveyor is positioned at an end of the separation screen to receive the second portion of the material.

A screen drive for a mobile material processing screen which can be at a travel width without having to fold or disable the screen drive. The screen drive system includes a drive motor, which is tucked at least partially under the vibrating screen; a sheave, having a double row ball bearing being supported by a shaft; a belt, coupling sheave and drive motor; a drive shaft coupled to a first universal joint, and a second universal joint, which is coupled to an opposing end of the drive shaft and to sheave.

A compact modular mobile aggregate processing system configured with no stand-alone inter-plant conveyors for decreasing the footprint of the system and an infinitely adjustable flow diverter(s) for increasing the control of and variation of output characteristics of the system; the system further including specialized folding conveyors.

A vibrating screening system, made up of at least two screening machines configured in a row and that can be set into vibration, each screening machine having a resiliently supported screening material feed end and a resiliently supported screening material discharge end. All supports of the last screening machine, in the screening material conveying direction, are supported directly on the supporting surface. The support provided respectively in the region of the screening material feed end of any earlier screening machine in the conveying direction is likewise supported directly on the supporting surface. In each case, the support provided in the region of the screening material discharge end of any such earlier screening machine in the conveying direction is supported in the region of the screening material feed end of the screening machine that is subsequent in the screening material conveying direction, on this subsequent machine.

A process for preparing whitened fly ash includes the steps of: (a) subjecting fly ash to a size classification step to obtain size classified fly ash having a particle size such that at least 90 wt % has a particle size of from 44 μm to 250 μm; (b) optionally, contacting the size classified fly ash from step (a) with water to form a slurry, wherein the slurry has a solid content of less than 40 wt %; (c) subjecting the slurry obtained in step (b) to an exhaustive magnetic separation step to form magnetically treated fly ash, wherein the exhaustive magnetic separation step includes a first magnetic extraction step and a second magnetic extraction step, wherein the second magnetic extraction step is carried out at a higher magnetic field strength than the first magnetic extraction step; and (d) subjecting the magnetically treated fly ash obtained in step (c) to milling to form whitened fly ash.

A mobile machine for conveying and/or processing mineral aggregate material, includes a machine frame and a conveyor module supported on the machine frame so as to be displaceable relative to the latter. A conveyor line runs along a virtual conveyor path (FB), the conveyor module being designed at least for conveying the aggregate material along the conveyor path on the conveyor line. A component carrier in a working state of the machine runs in an elevation direction (H) at a distance from the conveyor line crosswise with respect to the conveyor path above the conveyor line. The component carrier supports at least one functional module which interacts with the aggregate material conveyed on the conveyor line. The conveyor module is displaceable relative to the machine frame with a displacement component in the elevation direction. The component carrier is movable both relative to the conveyor module and the machine frame.

A mobile machine for separation and recovery of spent shot, the machine including a drive unit to provide self-propelled mobility to the machine, a charged soil collection assembly mounted relative to the drive unit to collect soil charged with spent shot, and at least one separation assembly to separate spent shot from other collected material, the spent shot conveyed to a collection vessel for disposal.

Machine, especially a padding machine, (10) for the burying of pipes, in particular arranged in a respective excavation of the ground, quali gas pipelines, oil pipelines, aqueducts, or altri, in particular for la covering of said pipe with a corresponding material, in particular un treated material, preferably screened or frantumato, comprising a main support framework (12) of the apparatus, in particular which extends according to a respective longitudinal axis of the same machine (10), a cabin (24) for housing the driver of the machine (10), such a cabin is in the form of a cabin movable with respect to said main support frame (12). Said cabin (24) for housing the driver of the machine (10) can be positioned, in corresponding vertical positions, or placed at height levels different from each other, preferably moving vertically, or perpendicularly to said ground.

A build material recovery system for a three-dimensional (3D) printer can include a selective solidification device to create a 3D object using build material, a build processing device to separate the 3D object from unfused build material, a material separating and conditioning device to condition the unfused build material, and a material storage device to store the conditioned build material.

A mobile mineral material processing plant is adaptively coupled to a screen module using an elongated coupling base that has first and second adapters to respectively detachably attach together a screen module, one or more exit conveyors and to detachably attach the screen module and the one or more exit conveyors to the plant. The first adapter pivotably couples to the plant on laterally moving the plant to engage with a first connector of the first adapter. The second adapter allows an actuator to lift the screen module with the coupling base so that the screen module pivots from ground about the pivotable coupling to an inclined operating configuration. The coupling base is angled to horizontally align a reject conveyor in the inclined operating configuration.
