A vibrator separator system has a vibrator separator position and a vibratory basket, a screen assembly positioned in the vibratory separator, and a vibration amplifier coupled to the vibratory separator. The vibratory basket has sides arranged in spaced relation to each other. The vibratory separator has at least one motor affixed thereto. The screen assembly extends between an inlet end and a discharge end of the vibratory basket. The motor is cooperative with the screen assembly so as to impart a vibration frequency to the screen assembly. The vibration amplifier is positioned beneath the screen assembly. The vibration amplifier is cooperative with the screen assembly so as to exert a force against a portion of an underside of the screen assembly.

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

Systems and methods for cryogenic separation of plant material are provided. A vessel is filled with cryogenic fluid having a temperature at or less than −150 degrees Celsius. Plant material is placed into the vessel via a basket and agitation is provided to the plant material in the vessel for a predetermined time period. Upon completion of the time period, the basket having at least a portion of the plant material is removed from the vessel. Plant particulates separated from the plant material during the agitation settle to the bottom of the vessel. The vessel is drained of the cryogenic fluid, including plant particulates separated from the plant material.

An apparatus for processing aggregate material includes a chassis, a trough mounted on the chassis at an inclined angle, and at least one shaft rotatably mounted within the trough and extending from a lower to an upper end of the trough. The at least one shaft has blades mounted thereon, the blades being angled so that they carry material within the trough towards the upper end of the trough when the at least one shaft is in a normal direction of rotation. A discharge opening is formed in a base of the trough adjacent the upper end of the trough, a weir being provided in the trough upstream of the discharge opening over which processed material must pass to reach the discharge opening.

Systems and methods are provided for separating seed from wet material. The method includes aerating raw, wet material comprising seed to provide an aerated material and aspirating the aerated material. The aspirating separates seed from liftings of the aerated material, and the separated seed can then be recovered.

A processing system for a slurry material. The system has a vibratory screen disposed atop an open-topped tank. A travel path for a vehicle is disposed directly above the screen and the tank. Slurry material dumped from the vehicle onto the screen is separated at the screen into a particulate-rich stream and a fluid-rich stream. The fluid-rich stream may be pumped to a cleaner so that it may be stored and re-used as drilling fluid. The screen may be a conveyor which removes the particulate-rich stream from above the tank.

A continuous sieving apparatus is described. The continuous sieving apparatus includes a sieve surface attached to a wall. A set of openings is formed in the sieve surface so as to define a set of pathways extending through the sieve surface. The set of opening are defined by a length dimension that is greater than a width dimension. An action system is configured to move the sieve surface in one or more directions (e.g., horizontally and vertically). Such movement causes a first pupa having a first cephalothorax width that is less than the width dimension to move through any one of the set of openings, and a second pupa having a second cephalothorax width that is greater than the width dimension to be prevented from moving through the set of openings.

A method of treating contaminated materials such as oil and gas production waste sludges to recover crude oil hydrocarbons. The method includes the inversion of water-in-oil emulsions, and subsequent separation steps. These may involve the separation and removal of asphaltenes, petroleum waxes and/or solid particles from the crude oil hydrocarbons. The treatment method uses the physical phenomena of hydrodynamic cavitation and hydraulic shock, which produce different effects upon a mixture of water and the contaminated material being treated. These are deployed either as single or combined stage(s) of treatment or as a repeated series of single/combined treatment stages, with or without additional processing operations between each single/combined treatment stage. The method may be implemented with suitable plant including hydrodynamic cavitation units (103, 106) and hydraulic shock units (104, 107), followed by separators (105, 108).

A sieving apparatus for separating insect pupa is described. In an example, the sieving apparatus includes a sieving device attached to an actuation system. The sieving device includes a set of openings sized to correspond to a cross-sectional cephalothorax width of a representative pupa of a population of insect pupae to be separated. The actuation system is configured to move the sieving device in a manner that causes smaller insect pupae to pass through the set of openings. Larger insect pupae remain within the sieving device. Such movement can include moving the sieving device with respect to a liquid held in a basin of the sieving apparatus.

A system for separating components from a slurry of drilling fluid and drill cuttings on a shaker screen having an upper side and a lower side within a shaker. The system also has a pressure differential generator to pull an effective volume of air through a section of the shaker screen to enhance the flow of drilling fluid through the section of the shaker screen and the separation of drilling fluid from drill cuttings and further maintain an effective flow of drill cuttings off the shaker. A method of separating components of a slurry of drilling fluids and solids has the steps of delivering the slurry to a shaker, flowing the slurry over a first screen and applying an effective amount of vacuum to a first portion of the first screen to remove the drilling fluids from the slurry without stalling the solids on the first screen.
