Abstract: Aggregate processing systems, methods, and apparatus are described. In some embodiments, a plant is configurable in one of a plurality of configurations, e.g. by sliding one of a plurality of chutes, hoppers, or flumes into a frame and/or by modifying a height of the frame. In some embodiments, a roller floor assembly is in a maintenance configuration when a chute is in a maintenance position. In some embodiments, a flume includes one or more diverters for moving a subset of material from one side of the flume to another.

Abstract: Systems, methods and apparatus are provided for creating an at least partially desegregated stockpile. In some embodiments the stockpile comprises one or more windrows. In some embodiments an operating speed (e.g., belt speed) of the conveyor is varied to create windrows at various distances from the conveyor.

Abstract: Conveyor idler monitoring apparatus, systems and methods are provided. In some embodiments, one or more sensors (e.g., temperature sensors, load sensors, etc.) are supported by the shaft of a conveyor idler. In some embodiments, one or more sensors are in data communication with a wireless transmitter. In some embodiments, a power generator driven by rotation of the idler is in electrical communication with one or more sensors and/or a wireless transmitter. In some embodiments, a plurality of idlers monitoring systems are in data communication with a conveyor monitoring system and/or operational monitoring system.

Abstract: Aggregate washing systems are described including mechanisms for slurrying, washing and/or dewatering aggregate material.

Abstract: Vibratory screens and apparatus therefore are disclosed. In some embodiments, a damper is incorporated having a pin and pivot arm which cooperate to dampen high-amplitude vibratory motion of the screen. In some embodiments, a bumper is disposed transversely adjacent to a sidewall of the screen and mounted to a bracket supporting a damper. In some embodiments, one or more guards protect openings in a pivot arm of the damper.

Abstract: Systems for automatically leveling a base frame of a bulk material transport conveyor include radial travel wheels mounted on generally opposing sides of the base frame that can move from a raised position above the ground to a lowered position in contact with the ground to permit radial travel of the conveyor. Actuators normally used to raise or lower the radial travel wheels may be actuated automatically by a controller in response to a signal from an inclination and/or limit sensor mounted on the conveyor that represents a non-level orientation of the conveyor, to level the base frame.

Abstract: Systems, methods and apparatus are provided for leveling and/or supporting a plant chassis. In some embodiments, a first set of actuators carry out a leveling routine and a controller monitors a pressure in a second set of actuators as the second set of actuators is extended.

Abstract: A dewatering device for aggregate product can be used to retro-fit existing aggregate product dewatering facilities in order to more efficiently capture product. The dewatering device can be movable to allow for the portability of the device relative to existing dewatering facilities. The device is adapted to receive a slurry of aggregate product and water and to vibrate to dry the aggregate product. A recycle system is included to receive any fines that may otherwise be lost by the system. The recycle system captures the fines and redirects them back towards the vibrating process of the vibrating device to direct them towards an exit of the vibrating device in order to use said fines as well as the other dewatered aggregate product. The portability of the device allows the device to be used with the existing facilities without the need to completely replace existing components for dewatering aggregate product.

Abstract: Conveyors are disclosed having transport and operational configurations. Some embodiments include conveyor sections supportable on an upper support rail. Some embodiments are sized to be transported in a conveyor. Some embodiments include conveyor sections slidingly engaged with one another. Some embodiments include a reel for supporting a conveyor belt. Some embodiments include individually foldable conveyor sections.

Abstract: Systems, methods and apparatus are provided for crushing aggregate material. In some embodiments, in an operating configuration a recirculating conveyor deposits material previously crushed by a crusher into the feed inlet of the crusher. In some embodiments, the recirculating conveyor is pivoted inward about a vertical axis into the operating configuration.

Abstract: Vibratory classifier apparatus are provided, e.g., for classification of materials such as wet or dry aggregate materials. In some embodiments, a drive system of the vibratory classifier apparatus includes a housing that can optionally be modified to allow access to a belt or other components of the drive system.

Abstract: Radial conveyors and undercarriages therefor are disclosed. Some embodiments include a wheel assembly with transport and operational configurations. In some embodiments, a wheel of the wheel assembly is selectively aligned with a tail pivot of the radial conveyor.

Abstract: Classifying tanks, related systems and methods of operating the same are described. Some classifying tank embodiments facilitate the use of a control system and methods to perform one or more of the following tracking the product discharged, performing optimization routines, and determining new settings for a plurality of stations of the classifying tank.

Abstract: Vertical shaft crushers and control systems therefor are disclosed. In some embodiments a rotor of the crusher is reversible and/or autogenous. In some embodiments a crushing chamber of the crusher includes at least one anvil and at least one rock shelf chamber.
