A padding machine for moving along a side of a ditch, scooping up excavated material from the side of the ditch, and sifting the excavated material into padding material for falling in the ditch comprises a frame comprising side frame members and frame rails spaced apart from the side frame members. A screening belt is driven around pulleys supported by the frame. The screening belt comprises a screen for collecting and conveying the excavated material upwardly. The screen comprises apertures for sifting the excavated material into padding material by permitting the padding material to fall through the apertures of the screen. The screen runs over the frame rails which support the screen. A discharge conveyor is mounted to the frame beneath an upper run of the screening belt. The discharge conveyor receives the padding material passing through the screen and discharges the padding material into the ditch.

A bucket with a vibrating screen is provided. The bucket includes a bucket member having an inner volume. The bucket member includes an first portion having a first opening to access the inner volume and a tapered second portion having a second opening to access the inner volume. The second opening is smaller than the first opening. The bucket includes a screen removably coupled to the bucket member within the inner volume in a location between the first portion and the second portion. The bucket includes a vibration generation device coupled to the screen.

A method for converting material within a vacuum tank that contains a mixture of liquid and solid material into a solidified batch of material. The method utilizes various devices to measure different features and properties of the tank and its contents to determine an amount of drying agent to be added to the tank. The method further utilizes various devices and methods for adding the drying agent to the tank and mixing the drying agent with the material within the tank. The method described herein may be completed automatically in response to human input on a handheld display device.

A dewatering system for separating water from solids in dredged slurries in real-time, parallel to the dredging of harbors, stream, and lakes. Water removed from the solids can be returned to the body of water from which it came. After the system removes debris and sand from the slurry, the system removes capillary water the remaining fines and filters out most toxic particles.

A material processing apparatus has as a power supply system comprising an electrical power supply and a hydraulic power supply. The electrical power supply comprises a battery pack and an electrical generator. The power supply system is operable in different power supply modes in which said at least one battery and/or said electrical generator supply electrical power to the electrically powered components of the system.

The process and practice of extracting and/or removing precious metals and/or other elements from landfills or other environments designated for the processing, storing, and final disposal of municipal solid or construction waste. This process applies to all landfill operations, when the intent is to recover precious metals (e.g. Gold, Silver, Platinum, Palladium, Rhodium, etc.) or other valuable soil materials (due to decades or centuries of decomposing trash), and includes the inadvertent discovery of such materials during land reclamation or remediation activities that require the use of earth moving equipment/machinery such as excavators, front end loaders, etc.

Hydro excavation vacuum apparatus that process spoil material onboard the apparatus by separating water from the cut earthen material are disclosed.

The present invention is directed to a drilling fluid reclaimer. The reclaimer has at least one adjustable screen assembly for providing a leveling filter for reclaimed drill fluid. Used drill fluid is placed at the screen assembly at the front the of the screen assembly. The at least one screen is vibrated to separate large particulate matter from liquid drilling fluid. A second screen is provided for additional filtering. Large particulate matter is expelled by a chute at the back of the screen assembly. Drilling fluid passing through the screen is “reclaimed” for use with a drilling system.
