An arrangement and a method for mixing and handling industrial side-stream materials. The mixer (6) is arranged onto a movable work machine (5) and it is used for mixing at least two side-stream materials to form a geopolymer. The side-stream materials are processed between a waste pile (4) and a casting area (13) in the mixer (6). Cast paste is allowed to harden and after that it is crushed to obtain an earthwork material.

An all-in-one mobile wellsite service unit for providing equipment and services at an oil and gas well related to well abandonment is provided. The mobile unit comprises a water storage tank, at least one cement mixing barrel for mixing a cement slurry, a progressive cavity pump for pumping the cement slurry, and a hydraulic hose for connecting to a hydraulic power source to provide power to the cement mixing barrel and the progressive cavity pump. The mobile unit may also contain downhole tools needed for well abandonment, including a well cleaning tool, a cementing tool, a hydraulic packer, and more.

A mobile chemical mixing plant includes an inlet for receiving fluid; a fluid conduit for conveying the fluid from the inlet; a container for containing a chemical therein; a chemical pump for withdrawing the chemical from the container and directing the chemical into the fluid conduit for mixing with the fluid in the fluid conduit to form a chemical mixture; and a homogenization pump for pumping the chemical mixture in the fluid conduit out of the mobile chemical mixing plant. The fluid conduit connects the chemical pump to the homogenization pump. The mobile chemical mixing plant is fixed to a trailer that is attachable to a vehicle. Because the fluid conduit directly connects the chemical pump to the homogenization pump, the mobile chemical mixing plant does not need an intervening mixing tank for mixing the fluid and the chemical.

A proppant delivery assembly receives and supports a plurality of containers having proppant stored therein. A cradle has a top surface which receives and supports the plurality of containers when positioned thereon. The cradle enables the plurality of containers to dispense the proppant stored therein. A proppant mover is positioned to underlie and extend along the top surface of the cradle aligned with the plurality of containers to receive proppant from the plurality of containers. The proppant mover carries proppant away from the plurality of containers. A chute is coupled to the cradle for receiving proppant from the proppant mover and directing the proppant to a blender hopper. A hood assembly is disposed at an end of the chute opposite the proppant mover for directing a vacuum air flow that removes a volume of air containing proppant dust particles directed from the chute. The hood assembly includes a curtain extending about a perimeter of the hood assembly and downward therefrom to at least partially define the volume of air being removed by the hood assembly.

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 closed concentrated dry chemical dispersion system including a closed ingredient container having a volume of dry ingredient therein. The system provides a fluid container and a mixing chamber in which the dry ingredient and fluid can be mixed to form a formulation for delivery to a device such as agrochemical dispensing equipment. The system minimizes worker exposure to the chemicals and enables lower packaging and transportation costs.

A feed mixer and liner therefor. The feed mixer including: a container formed from two side walls, two end walls, wherein the end walls have a slope and curvature and are connected to the side walls to form an auger well, and a base connected with the side walls and end walls at a lower end thereof; and a liner configured to have a truncated conical shape that matches the slope and curvature of the end walls and fits within the auger well such that: a bottom of the liner contacts the base and has a diameter similar to a diameter of the path of the auger at the base; and a top of the liner contacts with the end walls and side walls. The auger well may include two auger wells and the liner may include two truncated conical shapes fitting in each of the two auger wells.
