The BPU comprises a transformer having an input and an output and configured to receive electrical power via the input at a first voltage to output electrical power via the output at a second voltage; a motor power bus coupled to the output of the transformer; a motor starter bus; at least one motor soft starter having an input coupled to the motor power bus and having an coupled to the motor starter bus; a plurality of electric power relays coupled to the motor power bus and configured to supply electric power from the motor power bus to a load when in a closed state; and a plurality of start electric power relays coupled to the motor starter bus and configured to supply electric power from the motor starter bus to a load when in a closed state.

A technique facilitates mixing of fluids for use in well treatment operations. According to an embodiment, a dry powder material, e.g. a friction reducer, may be thoroughly mixed into fluid or fluids associated with a well treatment operation. The powder material is combined with liquid, e.g. water, via a series of Venturi mixers arranged to thoroughly mix the materials. In some applications, the Venturi mixers are mounted on a modular unit which is readily moved to a desired wellsite. Additional modular units may be added to increase the amount of product being mixed according to the demands of a given well treatment operation, e.g. a hydraulic fracturing operation.

The disclosed apparatus, systems and methods relate to devices, systems and methods for mixing particulate matter such as salt with moisture. In various implementations, the mixer is transportable. In various implementations the mixer comprises a hopper, at least one auger, and a mixing housing. Various implementations, additionally include at least one liquid tank.

A method includes the step of receiving a first weight value from a sensor associated with a feed mixer. A first rotation speed associated with the first weight value is monitored. A second weight value is received from the sensor associated with the feed mixer and a second rotation speed associated with the second weight value is monitored. A mixing profile is generated based on the first weight value, the second weight value, the first rotation speed, and the second rotation speed. In one embodiment, a first feed ingredient is associated with the first weight value and a second feed ingredient is associated with the second weight value.

A mixing drum includes a body defining a discharge aperture, a head coupled to the body opposite the discharge aperture, and a mixing element. The body includes an inner layer defining an interior surface of the body and an outer layer defining an exterior surface of the body. The head includes a connecting flange extending between the inner layer and the outer layer of the body. The head and the body define a volume. The mixing element is positioned within the volume and coupled to the body.

The invention refers to field of preparation to agriculture works, more specifically to the helping operations, before seeding and fertilizing the soil.

The method of preparation to agriculture works includes in it: placement of a few types of seeds and/or fertilizes in mobile capacity, which have at least one separating wall, which separates this capacity to at least two capacities for separating storage of content, moving of mobile capacity to the agriculture work area moving the content of at least two aforementioned capacities with the help of apertures with adjustable closing in to movement device that working, located in lower part of aforementioned capacities, moving of mobile capacities content in to destination point and mixing of the content while moving.

Declarant invention provides automation of process in mixing process of seeds and/or fertilizes, reducing time, needed for preparation to sowing and/or fertilizing the soil, increasing functional abilities while preparing to agriculture works.

The system, in one aspect, includes a first bulk storage container for holding a first bulk dry flowable material having a first dispensing assembly coupled with a first outlet, and a second bulk storage container for holding a second bulk dry flowable material having a second dispensing assembly coupled with the second outlet. The system, in one aspect, may further include a mixed storage vessel, as well as a controller in communication with the first dispensing assembly and the second dispensing assembly, the controller programmed to cause the first dispensing assembly to discharge the first amount of the first dry flowable material to the mixed storage vessel and cause the second dispensing assembly to discharge the second amount of the second dry flowable material to the mixed storage vessel over a comparable time period based upon weight based readings the controller receives from first and second load cells.

The invention provides a mixer feeder (1) comprising a mobile chassis (3), a tub (4) provided on the chassis (3) and at least one auger provided for rotation about a respective vertical axis of rotation. in the tub (4). Seen in vertical cross-section, the wall (12) of the tub (4) extends at least substantially upright from the bottom (6) of the tub (4). The wall (12) of the tub (4) curves inward at the upper side of the tub (4), sloping up and then extending downward.
