The unique shape of the helical beater described herein not only achieves higher mixing performance but also power efficiency. By using high strength plastics instead of metal, the improved helical beater design described herein will lower or fix material and manufacturing costs and will provide a better method of controlling the geometry of the beater body.

Preloading a plurality of feed types of a feed mix for livestock in a mixing plant. Feed types are conveyed towards a mixer. Bunkers selectively discharge one of the feed types on a loading conveyor. A controller controls a preloading weight of the feed types to be discharged onto the loading conveyor. Feed types are individually discharge onto dump spots of the loading conveyor at the bunkers and terminate when a predetermined total weight is reached or interrupt when a maximum preloading capacity is reached or feed reaches the end of the loading conveyor. Feed types may be individually discharged from the bunkers onto the dump spots and the main component loaded into the mixer by a loading vehicle, such that the weight of the main portion and the weight of the supplemental portion add up to a programmed total weight of the main component.

The invention provides a feed mixer for mixing feed including a mixing container for receiving feed, wherein the mixing container has a bottom and a wall extending upwardly from the bottom, wherein the mixing container includes at least one mixing auger rotatably arranged in the mixing container, wherein the at least one mixing auger is rotatably drivable about a vertical axis, characterized in that the pitch of the at least one mixing auger increases upwardly.

Systems and methods of producing a frozen food product include dosing ingredients with a liquefied gas while mixing the ingredients using self-cleaning interlocking beaters. The beaters are optionally also disposed to clean a container in which the ingredients are frozen. The rate and amount of cooling is controlled by measuring the quantity of liquid nitrogen, measuring viscosity of the frozen food product, measuring temperature, and/or the like.

A liner element for lining a vertical grinding mill agitator including one or more primary mounting portions configured to releasably mount the liner to a shaft of the agitator; and one or more secondary mounting portions configured to releasably mount one or more wear members to the liner. A liner segment including the liner element and at least one wear member is also disclosed.

A slurry mixing device includes an installation frame, a slurry mixing tank, a slurry feeding tank, a cooling mechanism and a slurry discharging mechanism. The slurry feeding tank is movably arranged under the slurry mixing tank, the cooling mechanism and the slurry discharging mechanism. A mass scale is arranged under the slurry feeding tank. A stirring cavity is formed in the slurry mixing tank, and a stirring paddle is arranged in the stirring cavity. A stirring motor is arranged on the slurry mixing tank. An outlet is arranged on the bottom of the stirring cavity. An oil bath cavity is formed between the slurry mixing tank and the stirring cavity. The cooling mechanism includes a lifting cylinder and a lifting base. The lifting base is provided with a rotating paddle and a rotating motor. The lifting cylinder is arranged on the installation frame.

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.
