The present invention relates to apparatus for manufacturing at least one liquid, by dissolving or suspending powders in solvents. The apparatus may be arranged for inclusion in a pellet coating system to supply the liquid to a downstream apparatus such as a Post Pellet Liquid Application (PPLA, 44). The apparatus includes: a mixing system, comprising a mixing pump (27), a mixing vessel (33) and piping for mixing substances located in the mixing vessel (33) by liquid recirculation; solvent supply means, comprising a supply tank (37) arranged to supply solvent to the mixing vessel (33); a feeding system, comprising a Hopper (32) for storing a first particulate material, a ramp arranged above a weighing tray (34) and a hopper vibrator (3.1) for feeding a first particulate material to the weighing tray (34); a weighing system located above the mixing vessel (33), the weighing system comprising the weighing tray (34), a weighing tray loadcell (5) for weighting a first particulate material and a weighing tray vibrator (4) for feeding a first particulate material to the mixing vessel (33); a blending vessel (40) to which a liquid comprising the first particulate material is transferred from the mixing vessel (33) and to which additional solvent may be added to reach a desired concentration of the first particulate material in the liquid; optionally a day tank (39) to which a liquid comprising the first particulate material is transferred from the blending vessel (40.1) for storage; and a control system, wherein a Programmable Logic Controller (PLC) (25) is arranged to receive signals from the weighing system and to control operation of at least part of the feed system according to the signals received from the weighing system to deliver a target mass of first and at least a second particulate material to the mixing vessel (33). The apparatus for manufacturing at least one liquid according to the invention may be connected to system for coating pellets, such as feed pellets. The system for coating pellets may include: the apparatus for manufacturing at least one liquid; a pellet source; a pellet coating device; means for feeding at least one liquid from the manufacturing apparatus to the pellet coating device; wherein the pellet coating device is arranged to apply the or each liquid to at least some of the pellets received from the pellet source. The present invention includes a method for manufacturing a liquid, by dissolving or suspending powders in solvents.

Provided is a mixing apparatus. The mixing apparatus comprises a housing defining a primary chamber, an inlet for receiving material into the mixing apparatus, as well as an outlet for discharging material from the mixing apparatus. The housing provides within the primary chamber a plurality of rotating shafts, each rotating shaft having a plurality of flailing fixtures associated therewith.

The present invention provides a method and system for providing on-site electrical power to a fracturing operation, and an electrically powered fracturing system. Natural gas can be used to drive a turbine generator in the production of electrical power. A scalable, electrically powered fracturing fleet is provided to pump fluids for the fracturing operation, obviating the need for a constant supply of diesel fuel to the site and reducing the site footprint and infrastructure required for the fracturing operation, when compared with conventional systems. The treatment fluid can comprise a water-based fracturing fluid or a waterless liquefied petroleum gas (LPG) fracturing fluid.

A main extruder and a side arm extruder are used in the extrusion of plastics with small amounts of additives or other small substances to be admixed. A minor portion of the plastic material is premixed with small quantity additive substances in a side arm extruder. The premixed material is discharged from the side arm extruder into the main extruder and there mixed with a major portion of feed material.

An apparatus for continuously producing chemically-modified cellulose, the apparatus having a first mechanism for transporting a fine-powder cellulose fiber starting material and a hydrophobizing chemical substance, a specific extruder, a solvent tank connected to the extruder, and a dryer connected to the solvent tank, and a method for continuously producing chemically-modified cellulose, the method having a step of washing, in the solvent tank, chemically-modified cellulose having been produced out of the fine-powder cellulose fiber starting material and the hydrophobizing chemical substance in the extruder, and then drying the chemically-modified cellulose in the dryer, in order to remove any unreacted hydrophobizing chemical substance.

In an apparatus for feeding animals including one or more feed dispensing containers from which the animals can take feed which are fed by supply ducts from a supply a device is provided which includes a feed supply duct portion arranged such that the feed falls through the feed supply duct portion under gravity. A drive member is mounted at the duct and includes a plurality of paddle blades of a wheel mounted for rotation about an axis of the wheel such that falling feed in the duct acts to drive the blades to rotate the wheel about the axis and a driven component driven by the wheel. The driven component is in most cases a dispenser for feeding a liquid or particulate additive material from a supply cartridge, which is mounted on a common housing forming the duct and containing the wheel, to an injection opening on the bottom of the housing for addition to the feed passing through the duct portion.

A brine maker including a hopper having upper and lower ends with a receiving tank positioned below the hopper. The forward end of the receiving tank has an opening formed therein. An elbow fitting is positioned in the opening in the forward end of the receiving tank and is welded to the forward end of the receiving tank. The elbow fitting includes a vertically disposed hollow upper portion which is positioned in the receiving tank and a horizontally disposed hollow lower portion which is positioned in the opening in the forward end of the receiving tank. The horizontally disposed hollow lower portion of the elbow fitting is fluidly connected to a pump. A shield is secured to the inner side of the forward end of the receiving tank above the upper end of the vertically disposed hollow upper portion of the elbow fitting.

A blending apparatus for coating product in flavouring is provided. The blending apparatus comprises a product dispenser configured to dispense a falling stream of product, a flavouring dispenser configured to dispense a falling stream of flavouring, and a deflection surface. The deflection surface is configured to deflect at least one of the falling stream of product and falling stream of flavouring, thereby bringing the falling stream of product and the falling stream of flavouring together. A method for coating product in flavouring is also provided. The method comprises the steps of dispensing a falling stream of product from a product dispenser, dispensing a falling stream of flavouring from a flavouring dispenser, deflecting the falling stream of product and the falling stream of flavouring using a deflection surface so as to bring the falling stream of product and the falling stream of flavouring together, thereby coating the product in the flavouring.
